title: Modification of deoiled cumin dietary fiber with laccase and cellulase under high hydrostatic pressure.
abstract: In this study, we evaluated the effects of high hydrostatic pressure (HHP) and enzyme (laccase and cellulase) treatment on the structural, physicochemical, and functional properties and antioxidant activity of deoiled cumin dietary fiber (DF). HHP-enzyme treatment increased the contents of soluble dietary fiber (SDF) (30.37 g/100g), monosaccharides (except for glucose), uronic acids, and total polyphenol. HHP-enzyme treatment altered the honey-comb structure of DF and generated new polysaccharides. DF modified by HHP-enzyme treatment exhibited improved water retention capacity (10.02 g/g), water swelling capacity (11.19 mL/g), fat and glucose absorption capacities (10.44 g/g, 22.18-63.54 mmol/g), α-amylase activity inhibition ration (37.95%), and bile acid retardation index (48.85-52.58%). The antioxidant activity of DF was mainly correlated to total polyphenol content (R=0.8742). Therefore, DF modified by HHP-enzyme treatment from deoiled cumin could be used as a fiber-rich ingredient in functional foods.
