The chemical composition, functional and pasting properties of acha, cowpea and carrot flour blends and sensory properties of the couscous prepared from acha, cowpea and carrot flour blends at ratios of 100:0:0; 90:5:5; 80:10:10; 75:15:10; 70:15:15; 65:20:15; 60:20:20; 55:25:20 and 50:25:25 were analyzed using standard methods. The moisture, crude protein, crude fat, ash and crude fiber contents increased from 9.38 to 14.49, 8.40 to 9.75, 1.59 to 2.62, 3.89 to 5.85 and 2.77 to 3.31%, respectively with increase in the addition of cowpea and carrot flours. While the carbohydrates decreased from 73.97 to 63.98% with increase in the addition of cowpea and carrot flours. The sodium, potassium, calcium, magnesium, zinc, iron and phosphorus contents of the couscous samples content ranged from 13.51 to 33.78, 89.10 to 128.44, 23.20 to 40.72, 1.80 to 4.44, 3.71 to 14, 125.72 to 196. 35 and 91.53 to 118.91 mg/100g, respectively. The average mean scores for mouth feel, texture and flavor increased from 5.75 to 6.88, 6.00 to 7.18 and 6.68 to 6.94, respectively, with increase in cowpea flour up to 20% and decreased with further increase. The most acceptable and preferred couscous blend was that with 20% cowpea and 15% carrot flour with corresponding improvement of 12.38% protein and 44.18% fiber content. The acceptability of acha-cowpea-carrot flour blend couscous could greatly improve the nutritional intake of the consumers and as well reduce importation of wheat flour and encourage commercial growth of cowpea and carrot in Nigeria.","PeriodicalId":504250,"journal":{"name":"Asian Food Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139842161","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}

Thirty samples of vegetable salads (i.e., Kachumbari), along with 30 swabs from hands and chopping boards, were collected and analyzed. High contamination levels exceeding acceptable limits were observed with total bacterial counts, S. aureus, and E. coli ranging from 3.6 to 6.7 log CFU/g. All Kachumbari samples (100%) were unsatisfactory, and 17 (56.7%) had unsatisfactory E. coli levels. Moreover, 22 samples (73.3%) had unsatisfactory S. aureus levels, and 10 samples (33.3%) showed unsatisfactory Salmonella spp. contamination. Further, Kachumbari from street food vending sites had a significantly (p < 0.05) higher TBC mean value (6.5 ± 0.3 log CFU/g) than the one from restaurants (5.2 ± 0.6 log CFU/g). On the other hand, chopping boards and hands had high total counts ranging from 3.5 to 4.7 log CFU.cm-2. Also, the type of chopping board was significantly related to the S. aureus contamination levels in the Kachumbari salads (p < 0.05). The presence of both hygiene indicator microorganisms and pathogens indicates a potential public health risk associated with the consumption of Kachumbari.
