The study investigated the effect of supplementation leaf powders Telfairia occidentalis , Amaranthus viridis and Solanum macrocarpon on chemical composition quality characteristics wheat bread. bread samples were supplemented with each vegetable at 1%, 2%, 3% during preparation. assayed for proximate composition, mineral physical, sensory, antioxidant properties using standard methods. addition significantly increased protein (9.50 to 13.93%), fibre (1.81 4.00%), ash (1.05 2.38%), fat (1.27...

Isoelectric precipitation was used to produce protein isolates (>90% contents) from three edible vegetable leaves. Amaranth (ALI), eggplant (ELI) and fluted pumpkin (FLI) leaf were isolated study their conformational structures. Intrinsic fluorescence indicated a loose structural conformation for ELI at all the pH values, whereas FLI ALI had more compact structures 3.0 9.0. The surface hydrophobicity showed greater distribution of hydrophobic amino acid groups basic than acidic regions....

Solanum macrocarpon (eggplant) leaf protein isolate (ELI) was hydrolyzed using four different enzymes to produce hydrolysates from alcalase (AH), chymotrypsin (CH) pepsin (PH) and trypsin (TH). CH had an overall stronger antioxidant property separated ultrafiltration membranes into <1, 1–3 3–5 kDa peptide fractions. Gel-permeation chromatography confirmed conversion of the ELI (average 22 kDa) that contained smaller peptides (<6 kDa). A total 23 consisting tri tetrapeptides were...

Amaranth leaf protein isolate (ALI) was hydrolyzed using four different proteases (alcalase, trypsin, pepsin, and chymotrypsin) followed by fractionation of the pepsin hydrolyzate (PH) into sizes ultrafiltration membrane. Gel permeation chromatography showed that all hydrolyzates had smaller size peptides (<7 kDa) than (>32 kDa). The chymotrypsin higher contents hydrophobic amino acid (44.95%) compared to alcalase (42.72%), (43.93%), trypsin (40.95%) hydrolyzates. PH stronger DPPH, hydroxyl...

Abstract The need to feed the increasing world population with high quality protein and enormous post-harvest losses of okra fruits necessitated research on seeds in this study. Whole flour (WF) matured seed was processed obtain defatted (DF), concentrate (PC) isolate (PI), followed by hydrolysis three different proteases; pepsin (PHp), pancreatin (PHc) trypsin (PH T ) produce hydrolysates. flours, proteins hydrolysates were analyzed for changes functional groups using Fourier, Transform...

Optimization of the yield, total phenolic content (TPC), and antioxidant activities (TAA) polyphenol concentrates extracted from Solanum macrocarpon leaves was studied using response surface methodology. The process variables investigated included extraction temperature (30, 50, 70°C), time (2, 4, 6 h), dried leaf powder : water ratio (1 10, 1 20, 30 w/v). Box–Behnken design resulted in 15 experimental runs. results showed following optimum conditions: temperature, 49.05°C; time, 243 min;...

The need to ensure availability of locust beans when off-season forms the basis this study. study investigated drying characteristics, nutritional composition and some anti-nutritional contents dried beans. Fermented were at 50°C, 60°C, 70°C 90°C. moisture fermented seeds determined different time intervals between 0 480 min. Lower content was achieved in a shorter higher temperature. bean samples had lower (12.36–12.76%) compared control sample (38.76%). Higher temperature resulted low ash...

Legumes and cereals stand a great chance as remedies to overcome incidences of protein malnutrition oxidative stress. Cereal grains such wheat (WT), millet (ML), maize (MZ) acha (AC) were blended with cowpea (CP), peanut (PN) soybean (SO) at varying levels produce four different blends. Protein contents the cereal-legume blends determined found be higher inclusion level legumes increased in Amino acid profiles antioxidant properties flour evaluated. Results showed that leucine was most...

Balanites aeqyptiaca (BA) seeds were toasted at 70 °C, milled and the oil expelled to resolve meal which defatted balanites protein concentrate respectively. These subjected analysis using standard methods. There exist marked trend between meal, incidences of diabetes. This work investigated anti- diabetic effects supplemented diets in streptozotocin (STZ)-induced rats. The rats fattened for two weeks with high fat diet (HFD) introduce Hyperglycemia then made by intraperitoneal...

Abstract Designing a good vehicle for functional ingredients is the major focus of this study. Small molecular weight peptides (&lt; 1 kDa) extracted from amaranth leaf protein (ALP), eggplant (ELP) and fluted pumpkin (FLP) were incorporated into freshly prepared orange juice at an effective inhibitory concentrations peptides. The rate degradation ascorbic acid was more in control (140.06 to 18.43 mg/mL) when compared with containing both storage conditions (140.08 32.32 mg/mL). However,...

The degree of hydrolysis (DH), proximate composition, functional properties and anti-oxidative characteristics enzymatic kariya seed hydrolysates were evaluated with a view to increasing the utilisation as food ingredient.Protein obtained from fermented unfermented protein isolate using two proteolytic enzymes: Pepsin pancreatin obtain hydrolysate (FPcKPH), (UPcKPH), pepsin (FPsKPH) (UPsKPH).The results showed that Original Research Article had higher (FPcKPH; 65.20% UPcKPH; 50.50%) than...
