Functional properties and biological activities of perilla seed meal protein hydrolysates obtained by using different proteolytic enzymes

다국어 초록 (Multilingual Abstract)

In this study, we aimed to determine the potentialfunctional properties and biological activities of thehydrolysates of perilla seed meal (PSM), which is a byproductof perilla seed oil extraction. PSM protein washydrolyzed independently by using five proteases, and theirfunctional and biological properties were analyzed. PSMprotein hydrolysate exhibited high solubility at most of thetested pH values, and the trypsin-treated hydrolysateexhibited the highest water and oil absorption capacity.
The neutrase-treated hydrolysate was most effective inscavenging the 1,1-diphenyl-2-picrylhydrazine radicals,whereas the pepsin-treated hydrolysate showed the highestangiotensin I-converting enzyme inhibitory effect, andanti-inflammatory activity. Trypsin-treated hydrolysateexhibited the highest scavenging activity against of 2,20-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid radicalswith the IC50 of 109.72 lg/mL. The results of the presentstudy suggest that the type of protease used for the treatmentsignificantly influences the functional properties andbiological activities of the resulting PSM proteinhydrolysates.
