Study on Production of High Activity Dietary Fiber from Soybean Dregs

Abstract

Abstract: The technics of using soybean dregs as the raw material with microorganism fermentation and high-pressurehomogenization to process high amount of dietary fiber was introduced in this study. Effects of fermentation conditions and homogenization pressures on SDF content were studied. The results showed that the amount of SDF is increased by 15% through fermentation and by more than 20% through high-pressure homogenization. The pretreatment of fermentation is propitious to increase SDF in high-pressure homogenization, and the contents of SDF can reach 30% when homogenized at 40MPa pressure.

Key words: , soluble dietary fiber(SDF)； fermentation； high-pressure homogenization；
