However, the trade raises public health concerns particularly due to the likely breaches of food safety standards. Thus, this study investigated the food safety practices of hawkers of cooked foods in Tharaka Nithi County. A cross-sectional study design was used to collect data from 151 respondents using a questionnaire. The other data collection tools included a key informant interview guide and an observation checklist. The mean age of hawkers was 40.25 ± 9.226 years, with 71.5% of them aged between 35 and 59 years. The majority of hawkers were females (77.5%), married (51.7%), had attained secondary level education (55.6%), and earned a daily profit of between Ksh. 501 and 1,000. The hawkers were largely (91.1%) not trained on food safety, did not have a food hygiene license (92.7%), did not wear outer garments (58.9%), and did not have a medical certificate (89.5%). Almost half (54.2%) of the hawkers prepared their foods at home and transported them to hawking sites using public means (52.6%). The majority (86.8%) of hawking sites were makeshift stations and 40.4% of them had reportedly been infested with rodents. Generally, the hawkers did not comply with most of the food safety standards. County government of Tharaka Nithi should therefore design and implement interventions to promote the safety of cooked foods hawked in the county.","PeriodicalId":7509,"journal":{"name":"African Journal of Food Science","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79073479","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 evaluated effects of processing methods on the nutritional and sensory attributes of a ready to eat snack bar developed from sorghum supplemented with sesame and baobab fruit pulp powder. The moisture content ranged between 6.38 and 10.28%, total fiber content ranged between 5.59 and 10.455 g/100 g while protein and fat content ranged between 11.28 and 16.74 g/100 g and 9.65 g/100 g and 18.58 g/100 g, respectively. The carbohydrates content in the snack bars ranged between 46.37 and 60.31 g/100 g, while energy content averaged 426.33 kcal/100 g for raw materials and 414.38 kcal/100 g for formulated snack bars. Concentrations of iron, calcium and zinc ranged between 5.46 and 14.611 mg/100 g, 82 and 246 mg/100 g, and 1.377 and 4.98 mg/100 g, respectively. Sensory evaluation of the bars formulations was based on a 5-point hedonic scale and revealed significant differences (p<0.05) in color, taste and overall acceptability. The aroma and crunchiness of the snacks were not significant. The study found underutilized crops have the versatility to improve the range of products and spur innovation in new product development.","PeriodicalId":7509,"journal":{"name":"African Journal of Food Science","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75561324","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}

Simultaneously, recent research highlights the importance of processing highly nutritious but underutilized African leafy vegetables (ALV) for lowering post-harvest losses and bridging off-season gaps. Combining both goals, it seems promising to utilize neglected ALV for enhancing conventional food items that are already well accepted in consumer diets but low in nutritional value. Therefore, this study analyzes consumer demand for maize (Zea mays L.) and millet (Eleusine coracana (L.) Gaertn) porridges combined with cowpea leaf powder (Vigna unguiculata L.Walp) (CLP) in Kayunga, Uganda. The study relies on combining sensory analysis with a binding Becker-DeGroot-Marschak auction to analyze consumer demand. Results show that consumer acceptance of CLP-enhanced porridges is predominantly shaped by sensory perception (p < 0.05). Although adding CLP lowers consumers’ sensory appreciation, the study still identifies a reasonably large group of consumers, nearly 50% of the participants, who valued CLP-enhanced porridges as much as plain ones. This justifies the conclusion that adding CLP is not without risks but is accepted among many consumers and can thus help to promote the consumption of locally available plants. For future product development, we recommend that priority is given to sensory attributes, and special focus is placed on consumers who barely incorporate fresh vegetables into their diets.","PeriodicalId":7509,"journal":{"name":"African Journal of Food Science","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89264336","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}

While compliance with food safety standards and regulations in FSEs is often viewed by the number of non-compliances or inspection violations cited during inspections, non-compliance with inspection recommendations may be an indication of continued non-compliance to the food safety standards. Using a cross-sectional study design, we assess the factors that influence compliance of FSE with inspection recommendations in Mansa Municipality, Zambia. This involved extraction of inspection process details from inspection reports for FSEs inspected was analyzed, followed by the administration of a questionnaire to FSE managers or owners on management and socio-economic factors. The data collected was subjected to both descriptive and inferential analysis. Importantly, the study results revealed that administrative enforcement, follow-up inspections, and reasonable time limits to make corrections are necessary factors to be considered in inspection processes for food establishments to comply with inspection recommendations. FSE owners compared to assigned managers exert more influence on the establishment’s compliance to inspection recommendations when actively involved in the daily operations. Well-operated inspecting institutions and FSE owners play key roles in facilitating FSEs' compliance with inspection recommendations as this ultimately facilitates compliance with food safety standards.","PeriodicalId":7509,"journal":{"name":"African Journal of Food Science","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81133134","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}

A total of 72 fresh M. caschive and O. niloticus were purchased, of which 24 were iced for reference and the other 48 were divided into two groups for pit and chorkor smoking. Experimental smoking of fish samples was conducted twice in a randomized design. Fish samples were analyzed for nutritional values using standard methods of the association of official analytical chemists and levels of PAHs using gas chromatography-mass spectrometry. Results revealed; the two smoking methods concentrated crude protein, fat and ash contents. However, fish smoked using chorkor had significantly higher nutritional values than fish smoked using pit kiln. About seven types of PAHs comprising of low and medium molecular weight were recorded from the two smoked fish species. Naphthalene and fluorene were the two dominant PAHs with fish smoked using pit kiln having significantly higher concentration levels of naphthalene (5.86±4.16 μg/kg) and fluorene (3.83±0.10 μg/kg) than fish smoked using chorkor oven. The study concluded that chorkor oven has better quality smoked fish than pit. Hence, its utilization and adoption for artisanal fisheries in South Sudan is recommended.","PeriodicalId":7509,"journal":{"name":"African Journal of Food Science","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90582909","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}
