Abstract

In this paper, potato peel were used as raw material. Taking water-insoluble dietary fiber as index, the effects of acid-alkali extraction time, concentration of acid extraction and alkali extraction on water-insoluble dietary fiber in potato peel were investigated by acid-base chemical method. The optimum process conditions for extracting dietary fiber were determined by neutral detergent method. The results showed that the yield of water insoluble dietary fiber could reach 12.6% when the acid-alkali extraction time was 35 minutes, the acid extraction concentration was 1.5%, the alkali extraction concentration was 1.6%.
