Study on extraction of water soluble dietary fiber from malus asiatica

摘要

In order to obtain the preparation technology of water-soluble dietary fiber, malus asiatica was used as raw materials by enzymatic and chemical methods in this paper. Optimum conditions for extracting the water-soluble dietary fiber in the raw materials were confirmed through orthogonal tests. The results showed that optimum condition of the malus prunifolia was as follow: 0.5% glucoamylase with reaction temperature of 60°C, hydrolysis time 60min, pH 12 alkali with hydrolysis temperature of 70°C and hydrolysis time of 90min.
