A cross-sectional descriptive research design was adopted by the researcher through the use of a structured questionnaire designed for this purpose. The study population comprises the employees of five (5) selected deposit money banks within the FCT metropolis in Abuja, Nigeria, which totaled 135 employees. The study adopted the use of census since the population was relatively minimal. Statistical Package for Social Sciences (SPSS Version, 22) was used to run the results of the multiple regression analysis to achieve the objectives of this study. Findings from this study showed that the adoption of Artificial Intelligence positively and significantly enhances efficiency, effectiveness, and productivity, improves customer satisfaction, and enhances the overall performance of the selected deposit money banks in FCT, Abuja, Nigeria. Hence, the study concluded that deposit money banks have the potential to bring significant benefits to their firms and customers by leveraging (AI) to improve customer experience, better understand customer needs, enhance competitiveness, and manage risk. The study recommended appropriate digital education for customers and employees of the selected deposit money banks in FCT, Abuja, Nigeria to enjoy some of the gains brought about by the use of Artificial Intelligence to enhance competitive advantage and outperform their competitors.</p> EO Okoliko, AO Ayetigbo, IJ Ifegwu, NU Chidiebere Copyright (c) 2023 EO Okoliko, AO Ayetigbo, IJ Ifegwu, NU Chidiebere https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/153 Mon, 25 Dec 2023 00:00:00 +0000 Geo-electric Ground Earthing Investigation in Basement Complex Environment https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/167 <p>The ground earthing investigation was carried out in the vicinity electrical transformer within the Iyana-emirin community, Ado Ekiti to understand the causes of incessant facility damage due to thunder strike and eventual explosion. Profiling measurement using the dipole-dipole electrode configuration was employed for three traverses around the facility while eight points along these traverses were sounded. The sounding data identified four lithologic layers (lateritic topsoil, clay, sandy clay, weathered layer, and basement) in the study area. 2D resistivity images were generated along four traverses with respect to depth. Results from the VES and 2D resistivity image indicated that the layer within the earthing medium is resistive. The study reveals that the facility damage experienced in the area is due to the high resistivity values across the study area getting above the recommended earthing standard (2 - 5 ꭥm)/(5 – 25 ꭥm) for substation installation. There is a need to carry out artificial enhancement by introducing conductive materials (like lime, salt, charcoal, and ashes) into the subsurface to reduce the resistivity thereby making it suitable for the intended purpose. Also, the identified low resistivity portion could be targeted for burying earthing/grounding material and further enhanced for better performance.</p> TE Oni, AO Falade, ST Akomolafe Copyright (c) 2024 TE Oni, AO Falade, ST Akomolafe https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/167 Mon, 25 Dec 2023 00:00:00 +0000 Characterization of Partially Purified Polyphenol Oxidase from Rhizome of Turmeric (Curcuma longa L.) https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/165 <p>Turmeric, a common spice with nutritional and nutraceutical applications undergoes brown reactions during harvest or post-harvest operations. This could possibly be due to presence of polyphenol oxidase (PPO) in the plant. In this work, isolation, partial purification and some characterization of PPO from rhizome of turmeric were described. The crude enzyme was purified using aqueous two phase partitioning. The partially purified PPO from turmeric was thereafter characterized. Aqueous two phase partitioning gave percentage yield and a final purification fold of 41% and 4.0 respectively. The optimum pH and temperature for the purified enzyme were 9.0 and 50 <sup>o</sup>C respectively. The enzyme was activated in the presence of some water-miscible organic solvents (DMSO&gt;acetone&gt;methanol). In contrast, the enzyme was inactivated in the presence of chloroform, butanol, petroleum ether and ethanol. In conclusion, the enzyme may find uses in several industrial and biotechnological applications.</p> OS Ilesanmi, VA Olagunju, AB Kayode Copyright (c) 2024 OS Ilesanmi, VA Olagunju, AB Kayode https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/165 Mon, 25 Dec 2023 00:00:00 +0000 Studies on the Physicochemical Properties of Amylases Obtained from Digitaria Exilis (White Fonio, Acha) and Digitaria Iburua (Black Fonio, Iburu) Under Optimized Conditions https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/164 <p>The need for indigenous cereals as a substitute to popular ones such as barley and wheat has necessitated the search for unpopular cereals like fonio. This study investigated the most appropriate conditions for the induction of amylases from acha and iburu using response surface methodology in water which is of traditional practice and water containing phosphate salts (10 mM sodium phosphate buffer, pH6.5). Malted grains as a function of days of germination produced the highest amylolytic activities on second day of germination with 24337 U/mgprotein when steeped in water and 15794 U/mgprotein for iburu steeped in water containing phosphate salt. However, white fonio produced lesser amount of amylases when steeped in water with 17948 U/mgprotein and 12046 U/mgprotein in water containing salt. These were purified using Concanavalin A Sepharose and were further purified on Bio-gel P100 gel filtration technique for a pure homogenate. The physicochemical properties of these homogenates were studied and white fonio was optimum at pH 6.0 while black fonio was pH 6.5. Similarly, both were stable to temperature at above 65<sup>o</sup>C. CaCl<sub>2</sub>.2H<sub>2</sub>O and MnCl<sub>2</sub>.4H<sub>2</sub>O activated activities of amylases from two grains but NaCl and KCl led to a reduction in activities while CuSO<sub>4</sub> and MnCl<sub>2</sub> absolutely inactivated activities of these enzymes. Physicochemical properties of these amylases are similar to that obtained from other grains, hence fonio can be used to totally replace amylases from other grains and as such promote the utilization of these local grains and as such improve the economy of our nation Nigeria.</p> OA Adefila, OV Ekundare Copyright (c) 2024 OA Adefila, OV Ekundare https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/164 Mon, 25 Dec 2023 00:00:00 +0000 Blockchain Technology: A Smart System Framework Towards Providing Human Immunodeficiency Virus (HIV) Patients in Nigeria, the Required Confidentiality https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/163 <p>Stigmatization in Nigeria has been for a long time.

In this work, we synthesized zinc oxide nanoparticles (ZnO NPs) from scent leaf, characterized the synthesized nanoparticles and established its antioxidant and photocatalytic activities. The biosynthesized <em>O. gratissimum</em> zinc oxide nanoparticles (<em>Og</em>ZnO NPs) were analyzed. Thermal gravimetric analysis transition shows a loss of 12.65% up to 650°C, indicating that the <em>Og</em>ZnO NPs is thermally stable after 650°C. The patterns indicated crystalline orthogonal shape with a particle size of 15.5 nm. The Fourier transform infra-red spectroscopy of the synthesized <em>Og</em>ZnO NPs revealed different bands. The peak in the region of 650 cm<sup>−1</sup> is assigned to Zn-O stretching vibration confirming formation of ZnO NPs. scanning electron microscope coupled with energy dispersive x-ray images and spectra revealed triangular crystalline shapes and presence of carbon and oxygen respectively. The percentage elemental compositions of the synthesized nanoparticles were 17.86%, 21.75%, 58.28%, 0.62% and 0.48% for carbon, oxygen, zinc, silver and nitrogen respectively<strong>. </strong>Strong absorption bands of the biosynthesized samples observed from UV-visible spectra at 350–400nm was characteristic band of ZnO nanoparticles. Free radical scavenging activity of the synthesized <em>Og</em>ZnO NPs revealed that it possesses high antioxidant property in a concentration dependent manner. The photocatalytic activity of <em>Og</em>ZnO NPs had absorbance degradation at 600 nm for methylene blue dye discoloration after 1 h, with a degradation maximum of 85%. In conclusion, the synthesized <em>Og</em>ZnO NPs could be used in several pharmaceutical and biotechnological applications.</p> OS Ilesanmi, OF Elijah, AB Kayode Copyright (c) 2024 OS Ilesanmi, OF Elijah, AB Kayode https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/162 Mon, 25 Dec 2023 00:00:00 +0000 Phyto-Constituents in White Butterfly (Clerodendrum volubile P. Beauv) Leaf Extract Demonstrated Antioxidant Activity and Inhibited Key Enzymes linked to Hyperglycemia and Hypertension https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/161 <p>Chlorogenic acid is bioactive phenolic compound found in medicinal and nutritional plants, linked to several therapeutic relevance, making it a highly commercialized phenolic compound responsible for the acceptability of the popular green tea. The aim of this research is to isolate chlorogenic acid from the white butterfly leaf and determine the antioxidant, hypoglycemic and angiotensin-1 converting enzyme (ACE-1) inhibiting potentials as a rider to further studies on the chlorogenic acid fraction. The chlorogenic acid isolate of white butterfly leaf (MLECS) was evaluated using biochemical analyses to determine its antioxidant properties, and inhibition of α-glucosidase and α-amylase activities, and ACE-1 activity. The characterization of the polyphenolic compounds revealed the presence of chlorogenic acid as the most predominant compound, while quercetin, ellagic acid, salicylic acid, p-hydroxybenzoic acid, and caffeic acid are in high amount. The chromatogram of the chlorogenic acid fraction showed a single high peak and the purity level of the chlorogenic acid isolate. The chlorogenic acid isolate demonstrated antioxidant properties, inhibited α-glucosidase, α-amylase and ACE-1 activities in a concentration dependent manner with varying IC50 values. The white butterfly leaf is nutritional and therapeutic with respect to the starch hydrolysis and angiotensin-II anabolism. The predominance of chlorogenic acid could increase the economic value as a commercial source of chlorogenic acid.</p> MC Oladipo, GO Oladipo, EO Ibukun, E Olorunfemi, T Elijah-Afolabi, DIA Ibiyemi, OO Oyebiyi Copyright (c) 2024 MC Oladipo, GO Oladipo, EO Ibukun, E Olorunfemi, T Elijah-Afolabi, DIA Ibiyemi, OO Oyebiyi https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/161 Mon, 25 Dec 2023 00:00:00 +0000 Acceptability of Quilt Bedspread Made from Textile Scrap for Wealth Creation https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/160 <p>Fabric waste in the garment manufacturing industry is one of the major issues facing manufacturing companies.

Ethanolic leaf extract of Okra plant (ELEOP) was prepared and administered to male and female WIstar rats in the following doses-10, 100, 1000, 2900 and 5000 mg/kg BWT to initially observe within 24 hours the autonomic, behavioral and neurological changes, and more importantly the lethality of the extract (LD<sub>50</sub>), followed by sub-chronic evaluation within 28 days. The spectrophotometric procedures to determine the activities of ALT, ALP and AST was conducted to evaluate effects on the liver function. And the effect on kidney functions was evaluated by the determinations of the concentrations of blood urea nitrogen and creatinine in female and male rats. The effects of the treatment on the histology of the kidney and liver tissues were examined. Also determined were the extent of the inhibition of lipid peroxidation using concentration of MDA generated and degeneration of protein mass using assay of total protein determination in the liver and kidney. Ethanolic extract of Abelmoschus esculentus Moench L leaf had an LD50 of 1250 mg/Kg BWT in female Wistar rats and 2333.33 mg/Kg BWT in male Wistar rats. The quantitative evaluation of phytochemical composition of the leaf extract revealed caffeic acid as the most predominant, other phytochemicals included coumarin, quercetrin, quercetin, kaempferol, gallic acid and chlorogenic acid. These are phytochemicals of antioxidative importance but that are required endogenously in limited amounts.</p> FB Borokini, GO Oladipo, OY Komolafe, MC Oladipo, KF Ajongbolo Copyright (c) 2023 FB Borokini, GO Oladipo, OY KomolafeMC Oladipo, KF Ajongbolo https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/159 Mon, 25 Dec 2023 00:00:00 +0000 Comparative Analysis of Wireless Signal Propagation: RS and GIS Approach https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/158 <p>Mobile network systems have become an integral part of daily life, facilitating communication and access to information. However, they are not without their challenges, particularly in the urban areas where signal strength can be affected by factors such as distance, vegetation, and building density. In this study, four different cellular networks signal strength was determined near their respective base stations in an ancient town of Osogbo, Nigeria exploring the free space method. The investigation of the signal strength was carried out mainly around built-up areas and vegetation/forest areas using a Blackberry 7290 wireless handheld receiver. The GPS and EM data obtained were fed into GIS to locate the cellular towers and to create the NDVI and digital elevation pattern map of the study area using the satellite images obtained for the study. Signal strength predicted by integration of Normalized Difference Vegetation (NDVI) methodology was compared with the four different cellular networks obtained. The comparative analysis reveals that values remains almost similar. The study found that RS and GIS approach can provide an effective means of analyzing cellular signal strength, useful for network planning and development in urban areas.</p> OB Daramola Copyright (c) 2023 OB Daramola https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/158 Mon, 25 Dec 2023 00:00:00 +0000 Antibacteria and Larvicidal Activities of Three Selected Botanicals https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/156 <p>Diseases have been part of man existence since time immemorial. The present scenario for controlling these diseases is aimed at application of target, cost-effective and biodegradable phytochemical products. Therefore, in the present study the larvicidal activities of <em>Gliricidia sepium, Azadirachta indica </em>and<em> Hyptis suaveolens </em>leaf extracts against anopheles mosquito was studied. Qualitative phytochemical screening was carried out while standard scientific protocols with minor modifications were adopted for the larvicidal bioassay. The results show that the plants contain all the phytochemicals screened with tannins, flavonoid and saponin being the most abundant. Also, <em>A. indica</em> exhibited the highest larvicida activity of 65% followed by <em>G. sepium</em> (60 %) and the control (water) was found to have lowest larval mortality percentage of 0% after 24 hrs. The calculated LD<sub>50</sub> were 0.48 mg/ml, 0.65 mg/ml and 3.18 mg/ml for <em>G. sepium, A. indica </em>and<em> H. suaveolens</em> respectively. These suggest that <em>G. sepium </em>and<em> A. indica</em> may be exploited for the production of antibiotics and biolarvicides. However, further investigations are needed to identify the active ingredient (s) of the extract responsible for the observed bioactivity in this study.</p> A Ogundare, AM Oyetayo Copyright (c) 2023 A Ogundare, AM Oyetayo https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/156 Mon, 25 Dec 2023 00:00:00 +0000 Biocontrol of Mosquitoes using Biocoil Produced from Cola millenii Extracts https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/154 <p>Malaria is one of the major causes of mortality and morbidity among various population in the tropics. Mosqiutoes are the vectors of this important disease. Presently, due to the resistance of insects to synthetic chemicals, there are ongoing efforts by researchers to develop biological substances for controlling the vectors in a bid to eradicate the disease. This research investigated <em>C. millenii </em>for its insecticidal potential against Anopheles mosquito. The leaf extracts of <em>C. millenii </em>were obtained using ethanol and n-Hexane. The extracts were screened for bioactive substances using standard analytical protocols. Biocoil was developed from the extract and the insecticidal efficacy was evaluated in the laboratory against larvae and adults of <em>Anopheles stephensi</em>. The qualitative results revealed that the plant contained alkaloids, saponins, tannins, glycosides, flavonoids and terpenoids in varying amounts. Furthermore, the leaf extract had a significant (<em>P</em> &lt; 0.05) lethal effect on mosquito larva at very low concentration recording a median lethal concentration (LC<sub>50</sub>) of 1.71 ppm in ethanol extract, while the pulp extract had LC<sub>50 </sub>of 792.34 ppm. The biocoil produced from the leaf extracts of the plant gave highly promising results in the control of the adult mosquito. These suggest that <em>Cola millenii</em> leaf contain bioactive substances that may be exploited in the control of mosquito.</p> BL Adewumi Copyright (c) 2023 BL Adewumi https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/154 Mon, 25 Dec 2023 00:00:00 +0000 Annona muricata (Soursop) Mitigated Testicular Toxicity and Prostatic Impairment in Testosterone-Propionate-Induced BPH in Male Rats https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/140 <p>Benign prostate hyperplasia (BPH) is an age-associated prostate gland enlargement in men that can lead to urination difficulty. The exact etiology of BPH is unknown. Several unscientific reports with few documentations, supporting <em>Annona muricata</em> (soursop) fruit against benign prostatic hyperplasia (BPH). This study aims to evaluate the mitigating mechanisms of <em>A. muricata</em> fruit phytochemicals on prostatic indices in BPH-induced male Wistar rats. The fruits of soursop were processed to obtain juice extract and lyophilized. A preliminary trial was conducted with six doses of the soursop fruit juice (10, 100, 1000, 1500, 2900 and 5000 mg/kg) to determine the LD<sub>50</sub>. The experiment involved forty male rats divided into five groups of eight animals each; groups 3 – 5 had 3mg/kg body weight of testosterone propionate (TP) intravenous for two days. Groups 3 and 4 had 1600 and 2900 mg/kg body weight of soursop fruit juice, while the effects finasteride was tested against BPH in the 5<sup>th</sup> group. The effects of the treatments were evaluated on body weight, prostatic weight, testicular weight, testosterone, DHT, prostate-specific antigen (PSA), testicular glycogen, testicular cholesterol, testicular zinc, 3β-hydroxysteroid dehydrogenase concentration and 17β-hydroxysteroid dehydrogenase levels. The soursop fruit juice significantly (p ≤0.05) decreased prostate weight and modulated indices of testicular functions positively. This study suggests that soursop fruit ameliorated prostatic hyperplasia in rats and may be considered as an affordable and non-invasive management option for benign prostatic hyperplasia in men.</p> OE Ibukun, LO Ogunlade, GO Oladipo Copyright (c) 2023 OE Ibukun, LO Ogunlade, GO Oladipo https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/140 Mon, 25 Dec 2023 00:00:00 +0000 Household Water Consumption Patterns in Ondo State, Nigeria https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/152 <p>The study was conducted in Ondo State using multi-stage sampling procedure.

In Nigeria, the consumption and sales of meat products are increasing. The aim of this work was to determine the microbial loads cow meat obtained from different market sources and antibiotic resistance of the isolates. Cow meat samples were randomly collected from local markets in five (5) different LGA in Ibadan, Oyo State, Nigeria and were subjected to microbial isolation and identification procedures using the serial dilution and pour plate methods and were identified using the colonial, microscopic, cultural, morphological and biochemical characteristics. The isolates were subjected to antibiotic susceptibility testing using the Kirby- Bauer disk diffusion method.&nbsp; Results obtained revealed that the predominant bacterial pathogen isolated was <em>Escherichia coli</em> followed by <em>Staphylococcus aureus, Salmonella</em> spp<em>, Campylobacter jejuni, Clostridium perfringes, Yersinia enterocolitica, Aeromonas </em>spp<em>, Pseudomonas aeruginosa and Shigella flexneri.</em> <em>S. aureus </em>and <em>Salmonella </em>spp were resistant to 80 % of all the antibiotics<em>. C. jejuni, </em>and <em>S. flexneri</em> showed resistance to 60% of the antibiotics while <em>C. perfringes</em> and <em>P. aeruginosa</em> showed resistance to 50 % of the antibiotics whereas, <em>E.coli</em> and <em>Aeromonas</em> spp. showed resistance of 40%. The lowest resistance of 30 % was recorded in <em>Y. enterocolitica. </em>The multiple antibiotic resistance index (MARI) of the isolates recovered in the present study indicates multidrug resistance in nature. The result of the study showed contamination of cow meat probably due to poor sanitary environment and dirty places during slaughtering, transportation and processing.</p> OT Jolapamo, OO Osatoyinbo Copyright (c) 2023 OT Jolapamo, OO Osatoyinbo https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/148 Mon, 25 Dec 2023 00:00:00 +0000 Resistance Evaluation, Gene Sequence and Plasmid Profile of Salmonella typhi Isolated from Human Anal Swab https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/146 <p>Antibiotic resistance in Enterobacteriaceae are of great global concern. <em>Salmonella</em> Sp. is widespread in the environment, but the main reservoir is the intestinal tract of livestock animals and particularly pig, poultry, and cattle and can be transmitted to humans through the food chain. Ten rectal swab samples were collected from five (5) male and five (5) females.&nbsp; One organism of clinical importance amongst the isolates was identified as <em>Salmonella typhi</em> through colonial, morphological and biochemical tests carried out following standard procedures. The identified isolate was investigated for its antibiotic resistance profile, Multiple Antibiotic Resistance index (MARi), pathogenicity status and its resistance genes were determined through molecular means using plasmid amplification and primers. Primers used include. <em>ermB, BlaTem, qnrB</em> genes. Result obtained showed <em>Salmonella typhi</em> to have α heamolysis. It was sensitive to 25% of the tested antibiotics, especially to all classes of Cephalosporin used. The Multiple antibiotic resistance index (MARi) was 0.66. The plasmid profiling revealed<em> Salmonella</em> to have low molecular weight plasmid and the molecular investigation using gene primers <em>ermB,&nbsp; BlaTem</em>,&nbsp; and&nbsp; <em>qnrB</em> genes showed <em>Salmonella typhi</em> to have resistance genes for macrolides (<em>ermB </em>gene) and betalactam (<em>BlaTem</em>) but no resistance gene quinolones (qnrB gene). The high antibiotic resistance of <em>Salmonella typhi</em> to antibiotics is a cause for concern and alternative means of intervention into the treatment of Salmonella associated infection should be investigated as a matter of urgency. Identifying and monitoring resistance in Salmonella isolates from human-related environments are of clinical and epidemiological significance in battling antimicrobial resistance.</p> AO Daniels, GV Iluyemi Copyright (c) 2023 AO Daniels, GV Iluyemi https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/146 Mon, 25 Dec 2023 00:00:00 +0000 Comparative Study of Nutritional Profile of Wild and Domesticated Oyster Mushroom (Pleurotus ostreatus) https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/145 <p>This study was carried out to determine the nutritional profile of wild and domesticated oyster mushroom. The wild mushroom was collected from forests around Owo and identified while the domesticated sample was grown on wood substrate prepared in the laboratory. Thereafter, the proximate composition and the mineral content were determined using standard techniques. The result of the proximate composition of the wild and domesticated <em>P. ostreatus</em> mushroom revealed that the moisture content and the Nitrogen free extract of the wild (8.96 % and 52.50 %) and the domesticated (8.59 % and 52.16%) mushrooms were comparable whereas, crude protein (32.11 %) and crude fibre (13.51 %) were significantly higher in the wild type than the domesticated samples. Also, lipids (0.42 %) and ash content (4.17 %) were significantly higher in the domesticated sample compared with the wild type. In the mineral content assay, nitrogen was found higher in the wild mushroom than the domesticated sample while potassium, calcium and magnesium were found to be higher in the domesticated samples than the wild types. Only phosphorus was found in comparable amount in both the wild and domesticated type of the mushrooms. Overall, there appears to be no significant (p&lt;0.05) differences in the nutritional content of both the domesticated and wild-collected test mushroom.</p> AR Jose, AM Oyetayo Copyright (c) 2023 AR Jose, AM Oyetayo https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/145 Mon, 25 Dec 2023 00:00:00 +0000 Design and Construction of a Tray Dryer for Groundnut Drying https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/144 <p>Drying is one of the oldest method of preserving food. Drying implies the removal of water from a product to an acceptance level for marketing, storage or for further processing. The numerous ways of usage of groundnut and its products has led to increase in its demand. However, the traditional method of drying involving exposing the groundnut seeds to sunlight and constantly spreading it to enhance uniform drying is associated with drudgery, unhygienic, time consuming, ineffective and results into high percentage seed losses. A tray dryer was constructed with the aim of improving on the traditional methods commonly used in Nigeria. The dryer can be used to measure drying rates of different varieties of groundnut at different initial moisture contents, drying air temperatures, drying air velocities of grain beds. The effects of different drying temperature, air velocity, can be investigated with the dryer. The dryer shows drying efficiency ranging from 77.54% to 79.32%. Also, the dryer is capable of reducing the moisture content of groundnut seeds of different varieties from 20% to average moisture content of 9% within average time of 7hrs.</p> OS Lawson, LAS Agbetoye, OO Olabinjo, OG Olajide Copyright (c) 2023 OS Lawson, LAS Agbetoye, OO Olabinjo, OG Olajide https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/144 Mon, 25 Dec 2023 00:00:00 +0000 Assessment of Some Quality Identities of Crude and Processed Oils Extracted From Snake Tomato (Trichosanthes Cucumerina) Seeds. https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/143 <p>Analysis of crude and processed oil extracted from Snake tomato (<em>Trichosanthes cucumerina)</em> seeds were carried out to establish the effect of processing on identity and quality characteristics of the oils. The crude oil was subjected to refining processes: Degumming, Neutralization and bleaching. There was no remarkable difference in the specific gravity, refractive index and moisture content of the crude and processed oils. However, there exists slight increase in Smoke point (<sup>0</sup>C): (82.00±0.01 - 87.00±0.33), Flash point (<sup>0</sup>C): (236.00±1.01 - 245.00±1.30), Fire point (<sup>0</sup>C): (285.00±2.41 - 296.00±1.58) and Iodine value (g/100g): (83.26±2.01 - 89.30±2.50) of the oil samples. The qualities of the oils improved by showing gradual decrease in Colour (Lovibond unit): (10.00 - 4.00), Free fatty acid (% Linolenic): (1.21±0.01 - 0.64±0.01), Acid value (mgKOH/g): (2.43±0.04 - 1.26±0.21), Peroxide value (meq peroxide/Kg) :(2.08±0.10 - 0.61±0.01), Saponification value (mgKOH/g Oil): (281.27±2.18 - 277.98±1.90) and increase in the values of Linoleic acid (38.10 – 41.98%), Oleic acid (35.74 – 37.50%), Palmitic&nbsp; (11.68 – 12.80%) and Stearic acid(3.79 – 4.66%) as the crude oil was processed to bleached oil. The oil's high proportion of unsaturated fatty acids, high iodine value, and low free fatty acid content are all attributes that qualify the oil to be safe for consumption. The oil's quality will be further enhanced if it is processed to the deodorization.</p> JO Alademeyin, AO Jide Copyright (c) 2023 JO Alademeyin, AO Jide https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/143 Mon, 25 Dec 2023 00:00:00 +0000 Antioxidative Effects of Sweet Potato (Ipomoea Batata) Tuber Peels and Leaves on Crude Groundnut Oil https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/142 <p>The aim of the research is to examine antioxidative effects of solvent extracts of potato leaves and tuber peels on groundnut oil stored under accelerated conditions. Sweet potato tuber peels (orange specie) and leaves were obtained, washed, dried, ground, and sieved with 40 mm mech and separately extracted with three different solvents (acetone, ethanol, ethyl acetate) for 72 hours. The efficiency of each solvent was determined as percent extractive value. The first two highest solvent extracts for potato peels and leaves were added as additives to the crude groundnut oil (CGO) at varying proportions (200 - 1000 ppm). A sample of oil containing no additives and sample with butylated hydroxyltoluene (BHT 200 ppm) were set aside for comparison. The progression of oxidation was followed by measuring the free fatty acid (FFA), acid value (AV) and peroxide value (PV) of the oils fortnightly for a period of eight weeks. Ethanol had the highest extractive values of 4.1667 &nbsp;and 6.4667 &nbsp;for leaves and peels respectively. The FFA, AV, and PV of the CGO with plant extracts were 1.952, 3.885 and 0.613 while CGO with BHT were 2.14, 4.476, and 0.736 respectively at P . This study showed that potato tuber peels and leaves had good antioxidant potential and therefore recommended to be utilized in our edible oil industries as an alternative to synthetic antioxidants.</p> JO Arawande, IA Adenegan Copyright (c) 2023 JO Arawande, IA Adenegan https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/142 Mon, 25 Dec 2023 00:00:00 +0000 Isolation, Purification, and Characterization of Gums from the Bark of Terminalia mantaly and Khaya senegalensis https://achieverssciencejournal.org/ajosrojs/index.php/ajosr/article/view/141 <p>This study investigates the physicochemical, mineral, proximate, FTIR, and SEM analysis of the gums obtained from the bark of <em>Terminalia mantaly </em>and <em>Khaya senegalensis</em>. The physicochemical analysis for <em>Terminalia mantaly</em> gum (TMG) gave values of 30.76 %, 4.50, 0.10 g/cm<sup>3</sup>, 0.142 mg/cm<sup>3</sup>, 8.78 %, and 10.55 % for percentage yield, pH, bulk density, tapped density, swelling index and water absorption capacity respectively while 29.50 %, 4.80, 0.12 g/cm<sup>3</sup>, 0.105 mg/cm<sup>3</sup>, 8.45 %, and 10.27 % for percentage yield, pH, bulk density, tapped density, swelling index and water absorption capacity respectively were recorded for <em>Khaya senegalensis</em> gum (KSG). The results of the proximate analysis showed that TMG had a higher percentage of moisture content, crude fat and ash content than KSG, and KSG had a higher percentage of crude fibre, crude protein, and carbohydrate content than TMG. Elemental analysis for <em>Terminalia mantaly</em> gum (TMG) gave values of 58.50 mg/kg, 42.0 mg/kg, 11.30 mg/kg, 38.50 mg/kg, 2.58 mg/kg, 1.53 mg/kg, and 0.33 mg/kg for potassium, magnesium, sodium, calcium, zinc, iron, and copper respectively while 58.00 mg/kg, 41.60 mg/kg, 39.00 mg/kg, 10.50 mg/kg, 1.50 mg/kg, 2.34 mg/kg, and 0.30 mg/kg for potassium, magnesium, calcium, sodium, iron, zinc, and copper respectively were recorded for <em>Khaya senegalensis</em> gum (KSG).
