 Abstract
This study was conducted for the production of water-soluble dietary fiber (SDF) from buckwheat hulls by using Celluclast or Viscozyme. The functionality of this SDF, including antioxidant activity, glucose- and bile acid-retardation effects in vitro, was measured. SDF yields from cellulose and hemicellulose fractions were 60.5 and 123.7 g/kg dry matter, respectively. Analysis of molecular weight distribution of SDF by using gel chromatography showed that SDF degradation increased with increase in reaction time. The antioxidant activity of SDF obtained by enzymatic hydrolysis was higher than that of dietary fiber without enzyme treatment. SDF showed higher retardation effects on glucose and bile acid than the sample without dietary fiber did. The results of this study suggested that SDF produced from buckwheat hull by enzymatic hydrolysis is a good source of functional food material because of its high antioxidant activity and glucose- and bile acid-retardation effects.
