Additionally, many people today are increasingly focused on healthy eating and seeking nutritious food options. The purpose of this study was to prepare gluten-free cookies using sorghum flour, sweet potato powder, and chickpea powder, while also assessing their physicochemical and sensory qualities. \u0000Methodology: Five gluten-free formulations were developed: control-100% sorghum flour as control, S1- 90% sorghum flour and 10% sweet potato, S2-80% sorghum flour + 10% sweet potato and 10% chickpea powder, S3-70% sorghum flour + 10% sweet potato and 20% chickpea powder, S4-60% sorghum flour + 10% sweet potato and 30% chickpea powder.  The physicochemical properties and sensory evaluation of cookies were carried out. \u0000Results: Results showed the inclusion of 10% sweet potato powder led to a significant increase in ash and fiber and carotenoids content in cookies furthermore, the increase of chickpea powder in cookies led to the increased proportion of crude fat, crude protein in cookies. Results also show an increase in mineral content with the increase in substitution with chickpea powder the addition of different levels of chickpea powder had a significant impact on the diameter and thickness of the cookies. As the chickpea powder level increased, there was a consistent decrease in cookie diameter and thickness. \u0000Conclusion: These findings suggest that the replacement of sorghum flour with up to 20% chickpea and 10% sweet potato powder was the most acceptable for the sensory characteristics of the gluten-free cookies.","PeriodicalId":8518,"journal":{"name":"Asian Food Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141374617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was aimed at evaluating the quality of biscuit produced from wheat, African almond and pawpaw flour blends. From the flours, blends were made and six (6) samples, A to F formulated. Sample A (100 % wheat flour) was used as the control, B (60 % Wheat flour: 0 % Almond Flour: 40 % Pawpaw Flour), C (60 % Wheat flour: 10 % Almond Flour: 30 % Pawpaw Flour), D (60 % Wheat flour: 20 % Almond Flour: 20 % Pawpaw Flour), E (60 % Wheat flour: 30 % Almond Flour: 10 % Pawpaw Flour), F (60 % Wheat flour: 40 % Almond Flour: 0 % Pawpaw Flour). The physical, proximate, anti-nutrients, vitamins, minerals, antioxidants and sensory properties of the biscuits were evaluated using standard methods. For physical parameters of the biscuit, the weight ranged from 8.86 g-10.60 g, diameter from 6.60 mm- 6.80 mm, the spread ratio from 0.58-0.61, breaking strength from 0.25 kg- 0.29 kg and thickness ranged from 11.08 mm- 11.43 mm. The anti-nutrients content of the biscuits were considerably low and within safe limits. The results showed an increase in ash, fibre, fats and protein content while the carbohydrate content of the biscuit reduced upon substitution of wheat flour with almond and pawpaw flours. The vitamin content of the biscuit was also improved especially the vitamin A content upon addition of pawpaw flour. The result for mineral composition showed a significant increase from 46.00-89.35mg/100g for sodium, potassium from 323.44-486.95 mg/100g, calcium from 189.46-356.88mg/100g, magnesium from 44.34-132.88 mg/100g and phosphorus from 155.33-428.45mg/100g.6. Antioxidant activity also increased from 2.12-3.69mgAAE/g. The biscuit samples were all rated high in terms of their sensory attributes especially samples with high proportion of almond flour.

This study aimed to evaluate the potential of bitter kola in weight management and prevention of obesity. \u0000Study Design: An experimental full 3×3 factorial design was used for this study, with the main responses being the anthropometric and biochemical parameters of the albinos Wistar rats. \u0000Place and Duration of Study: The study was carried out at the Food Science Laboratory of the Department of Nutrition, Food and Bioresource Technology of the College of Technology, The University of Bamenda, Cameroon, between February and July 2023. \u0000Methodology: Three bitter kola cultivars (Bafia, Penja, Widikum) were collected from their production areas, and their phytochemical content and antioxidant activity were analysed. The effect of their dry powder consumption on body weight and lipid profile was investigated on male Wistar rats consuming a high-fat diet. The rats were allocated to 10 groups of 6 rats including one control with the feed containing 0 g/kg of bitter kola powder, and 3 test groups per cultivar having 5 g, 10 g, and 15 g of bitter kola powder per kg of feed respectively. \u0000Results: Results revealed that antioxidant activity varies with cultivars and Widikum cultivar has the highest antioxidant activity and the highest phytochemicals content. Consumption of Penja and Widikum bitter kola powder induced the highest fat excretion in rat faeces. The effect of bitter kola consumption on body weight varies with cultivars and incorporation rate, and the highest anti-obesity effect was observed with the consumption of the Widikum cultivar at 10 g/kg of rat feed. The increase in bitter kola powder proportion in rat feed was negatively correlated with the atherogenic index of plasma and atherogenic coefficient. \u0000Conclusion: From the overall results, the consumption of feed with 15 g/kg of Widikum bitter kola cultivar had the best anti-obesity activity and hypolipidemic effect. Thus, bitter kola powder can be used to prevent obesity and cardiovascular diseases in high-fat diets.","PeriodicalId":8518,"journal":{"name":"Asian Food Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141125235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Even though good manufacturing practices are vital systems in food safety and is associated with minimum sanitary and processing requirements for the food industry, only a few studies have reported GMP implementation by small milk processing companies. Therefore, the present study was undertaken in milk processing firms to evaluate the implementation of good manufacturing practices for control of microbial contamination in milk and milk products. Purposive, random and stratified sampling techniques was used to identify milk processing companies. Ten processing facilities were purposively sampled for the study. The representatives were interviewed, using a pretested questionnaire and data was collected and analyzed. All the processors had qualified personnel handling milk and milk products with a daily processing capacity of 20000-30000 litres. It was observed that the processors complied with all regulatory and licensing requirements and had in place critical process controls with majority indicating pasteurization at temperatures ranging from 80-90oC as the most common method. The processors had several food safety management systems such as ISO 22000, GMPs, and HACCP which were handled by trained and competent staff. It was observed that all the processors tested for total viable counts (TVC), and E. coli while only 50% and 33.3% of the processors tested for S. aureus and L. monocytogenes respectively. Furthermore, the processors (33.3%) reported E. coli as the main contaminant while L. monocytogenes were not detected. A majority (83.3%) had well-documented cleaning programs and had a system of controlling cross contamination which was enforced through different colour codes (66.7%), memos and notices (16.7%) and through colour coding of processing equipment (16.7%).

Various preservatives are used to extend its shelf life, and among them, salt (NaCl) has generated controversy due to potential health risks associated to exposure to elevated concentrations of salt. The present study aims at assessing the effect of oyster shell powder on the quality changes of Afitin during storage at 30°C. Methodology: Oyster shell powder was added to the condiment just before the natural fermentation at concentrations of 0.5%, 1% and 2%. At the end of the 24 h natural fermentation, the product was stored at 30°C. Afitin samples which did not receive the oyster shell powder served as controls. Samples were taken for microbiological, pH, water activity, and sensory analyses just before the fermentation, at the end of the fermentation, and at days 2 and 4 during storage. Results: Oyster shell powder had a significant effect on the growth of microorganisms, on pH and water activity during the storage of Afitin. The average Total Viable Count (TVC) in the control samples was 8.9 Log CFU/g, whereas in the Afitin with 2% oyster shell powder, this load was 6.9 Log CFU/g after 2 days of storage. At the same time, the enterobacteria load in the control Afitin was 7.7 Log CFU/g, whereas in the Afitin with 2% oyster shell powder, it was below the detection limit. There was also a significant difference between the samples inoculated with 1% oyster shell powder and the control. From the sensory analysis, the control Afitin was rejected by the panellists after 48 h of storage, whereas the Afitin with 1% or 2% oyster shell powder was not rejected until the end of storage (4th day), indicating a notable prolongation of the product's shelf life by at least 100%.
