Abstract

This study was conducted with an aim to produce a novel water-soluble fiber (WSF) by enzymatic hydrolysis of perilla seed meal (PSM), which could be used as a functional food material. The cellulose fraction (CF) and hemicellulose fraction (HF) derived from PSM were hydrolyzed using Celluclast 1.5 L and Viscozyme L, respectively. Although WSF produced from PSM had low acetylcholinesterase inhibitory activity, WSF exhibited excellent antioxidant, antidiabetic and anti-dementia activities, and effectively delayed the diffusion of glucose and bile acid from the dialysis membranes. In particular, WSF produced from CF showed a significantly higher bile acid retarding index than pectin, and WSF obtained from HF had low IC50 values for radical scavenging activity and reducing power. Thus, these results suggest that the WSF derived from PSM by enzymatic hydrolysis can be used as functional carbohydrate source such as additive and a dietary supplement in the food industry.
