Dehulled sesame seeds were roasted for 7-13 min at 185 – 200 0C, defatted and milled into flour and tagged as DSDSF , African yam bean was toasted at 125 0C for 40 min, dehulled, milled into flour, and tagged as TDAYBF while Moringa leaf was sundried, milled into flour and tagged as MLP. All these flour samples were then blended into 18 ratios and tagged as LMDTM1-18. The  ratios of DSDSF:TDAYBF:MLP were  100: 0:0(LMDTM1), 0: 100: 0(LMDTM2), 95: 0: 5(LMDTM3), 95:5:0(LMDTM4), 90: 5:5(LMDTM5), 90:10:0(LMDTM6), 80:15:5 (LMDTM7), 80: 20:0(LMDTM8), 70:25: 5(LMDTM9), 70:30: 0(LMDTM10), 60: 35: 0(LMDTM11), 60: 40: 0(LMDTM12), 50: 45: 5(LMDTM13), 50: 50: 0(LMDTM14), 40: 55: 5(LMDTM15), 40: 60: 0(LMDTM16), 30: 65: 5(LMDTM17), and 30: 70: 0(LMDTM18). The flour blends were studied for physicochemical, functional and anti-nutrients properties. After blending, the formulated samples had proximate composition of  3.37 -9.21 % moisture, 18-27.5 % protein, 0.18-3.95 fat, 1.31 – 3.9 % ash, 3.2-8.88 % crude fiber and 52.75-65.45 % carbohydrate. Each proximate component varied significantly (p<0.05) between samples. While LMDTM13 had significantly(p<0.05) the highest moisture content, protein, and fat LMDTM6 had the highest ash content, LMDTM2 had the highest crude fiber and LMDTM1 had the highest carbohydrate. The control sample LMDTM1 had the highest bulk density (0.711), water absorption capacity (165.52 %), oil absorption capacity (94.5 %), protein solubility (13.4 %), foaming capacity (8.0 %), but lowest swelling power (3.5 %), emulsion capacity (46.2 %), phytate (16.29 mg/100g), tannin (4.64mg/100g) and Trypsin inhibitor (1.20 mg/100g) compared to other samples.  Blended flour mainly from plant sources of high-quality value can be blended when processed, giving the opportunity to increase its nutrition, consumption, and acceptability for biscuit- like production. In this study, sesame seeds were incorporated into African yam bean and moringa leaf powder to increase the quality and flavor replacing wheat flour in biscuit production.","PeriodicalId":8518,"journal":{"name":"Asian Food Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84687824","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}

Analyses of possible migrants from the packaging materials were carried out using standard methods. Raw ‘moi-moi’ paste and cooked ‘moi-moi’ samples were analysed for migrants from associated packaging material on day zero and day 3 of frozen storage.

The proximate compositions showed that the ‘moi-moi’ cooked in plantain leaf had the highest value in ash (9.14%), fibre (3.95%) and protein (21.41%) followed by that in aluminium foil with 6.47% in ash and 1.34% in fibre.

Fresh ginger rhizome was processed to flour by oven drying (OD), sun drying (SD) and ambient drying (AD).The ginger flour were incorporated into processed soymilk at 1 g and 2 g levels, respectively to obtain ginger spiced soymilk, which was stored for 21 days. The chemical composition and microbiological load of the soymilk were determined. The pH ranged from 6.6 to 4.7. The values decreased as storage time progressed. Total titratable acidity (TTA) ranged from 0.0015 to 0.0698 % and increased with storage time. Total soluble solids (TSS) decreased from 26.60 to 3.99 oBrix as storage time increased. Total solids (TS) decreased from 7.76 to 0.31 % during storage. The total viable counts of the control sample increased from 4.0×103 to 71×103cfu/mL while those of the treated samples increased from 0 to 33×103 cfu/mL, Coliform was not detected. Yeast and mould growth did not occur from day 0 to day 7 but increased from 2.0×103 to 5.0×103 cfu/mL on day 14 and 21, respectively.

The samples of saffron were purchased from different hyper-markets and local markets in Muscat, Oman. Saffron’s commercial value is determined according to the ISO standard which include moisture, ash, acid insoluble ash, extract %, sulfuric test, artificial colors, spectrum, Flavor, aroma and color. The saffron samples were in line with standard in terms of moisture, ash, acid insoluble ash and extract %.  The two powder saffron samples failed in sulfuric, spectrum and flavor tests. From the 19 samples of saffron filament, three samples were failed to achieve the flavor and color limits required by the standard. This failure to standard quality could be due to poor processing condition such as drying and packaging or due to adulteration. The standard parameters could not distinguish between low quality and adulteration due to its limited and unspecific parameters.

High density lipoprotein increased and the values ranged from 26.00 -50.34 mg/dl while cholesterol, very low-density lipoprotein, low-density lipoprotein, and triglyceride levels reduced and the values ranged from 16.17 to 42.28, 8.17 -9.16, 13.35 – 21.44 and 40.84 – 46.64 mg/dl, respectively in the rats fed experimental malt drink. \u0000Conclusion: Rats fed samples containing 50% unroasted finger millet malt, 25% of cucumber and 25% carrot drink had more weight gain (15.30%) and fasting blood glucose reduction (87%). Malted drinks from unroasted finger millet enriched with cucumber and carrot juice can be used in diabetes management.","PeriodicalId":8518,"journal":{"name":"Asian Food Science Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84849063","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}
