摘要:
Enzymatic digests of whey protein concentrates were prepared using animal, bacterial and fungal proteases, and evaluated for antihypertensive activities. The highest ACE-inhibitory activity was obtained with the purified peptide β-1g (f142–148) obtained by chemical synthesis, for which an IC50 value of 0.04 mg powder.ml−1 was found. The hydrolysates derived from BiPRO™ whey protein isolate and β-1g both gave higher antihypertensive activities (IC50 values of 0.29 to 0.90 mg powder.ml−1) than the other hydrolysates tested (IC50 values of 0.96 and 1.30 mg powder.ml−1). The recovered hydrolysate can be used to treat hypertension in mammals such as humans and domestic pets such as dogs and cats.
