Abstract
The process and elements of extraction of dietary fiber from water chestnut pericarp by zymochemistry method were studied in this paper.The optimum conditions of enzymolysis of α-amylase were determined by single factor test, then NaOH concentration, NaOH consumption, the affected time of NaOH, the affected temperature of NaOH as factors of single factor test and orthogonal test. Extraction of dietary fiber from water chestnut with 0.2mL/g α- amylase and 1.5h, then 2％ NaOH,4mL/g NaOH,50℃, and 1.5h lead to the highest extraction yield, 29.45％ dietary fiber, the purity was 93.30％ .Compared with chemistry method, zymochemistry method must be better.关键词
