The aim of this work was to produce antihypertensive protein hydrolysates through different forms enzymatic hydrolysis (2% pepsin, 4% 1% alcalase, 2% papain, and pepsin + pancreatin) hemp seed proteins (HSP). (HPHs) were tested for in vitro inhibitions renin angiotensin-converting enzyme (ACE), two the enzymes that regulate human blood pressure. HPHs then administered orally (200 mg/kg body weight) spontaneously hypertensive rats systolic pressure (SBP)-lowering effects measured over a 24 h...

ABSTRACT The nutrient and antinutrient composition of raw extruded blends acha soybean was evaluated. Acha grains were cleaned milled into flour separately sieved to pass 0.75–1.00 mm mesh. moisture content the flours determined. Soybean added at 25% levels substitution. adjusted levels. blend using a Brabender laboratory single-screw extruder (Duisburg DCE-330 model, Duisburg, Germany). Amino acid profile, proximate composition, minerals some water-soluble vitamins extrudate samples...

Thermoase-digested flaxseed protein hydrolysate (FPH) samples and ultrafiltration membrane-separated peptide fractions were initially evaluated for in vitro inhibition of angiotensin I-converting enzyme (ACE) renin activities. The two most active FPH their corresponding subsequently tested vivo antihypertensive activity spontaneously hypertensive rats (SHR). produced with 3% thermoase digestion showed the highest ACE- renin-inhibitory Whereas membrane resulted significant (p < 0.05)...

Abstract This study investigated short‐term (24 h) and long‐term (5 wk) systolic blood pressure (SBP)‐lowering effects in spontaneously hypertensive rats (SHR) of a 5 kDa membrane pea protein hydrolysate permeate (PPH‐5) produced through thermoase hydrolysis isolate (PPI). Amino acid analysis showed that the PPH‐5 had lower contents sulfur‐containing amino acids than PPI. Size‐exclusion chromatography indicated mainly low molecular weight (<10 kDa) peptides but not The renin angiotensin...

Extracts of the leaf, stem bark and fruit cashew plants were investigated to determine their phytochemical, antioxidant antimicrobial properties. Cashew leaves, barks fruits Brazilian Jumbo variety processed, extracted analyzed for activities. The results showed that phytochemical contents varied significantly between sample extracts. Carotenoids content extracts are 88.86, 125.93 100.33 mg/g respectively. extract highest tannin (2.01 mg/g) compared (1.56 leaf (1.19 mg/g). Total phenolic...

Peels of 3 varieties mango (Julie, Peter and Paparanda) were evaluated to determine the effects varietal differences on nutritional, phytochemical antioxidant properties peels selected varieties. from moderately ripe fruits processed into peel flour analyzed for their properties. The results showed that significantly differ each other in nutritional compositions. variety had highest values both vitamins A (β-carotene) C while Paparanda lowest values. Beta-carotene content ranged 9.14 11.98...
