酶解法提取甘薯茎叶中可溶性膳食纤维的研究
Extraction of soluble dietary fiber from sweet potato leaves and stems in the enzyme solution
摘要
Abstract
Through the single factor and orthogonal test of adding,amylase and papain effect of soluble dietary fiber on the extraction of sweet potato stem and leaf,and orthogonal optimization of extraction process on the basis of sin-gle factor were studied.The optimum condition of enzymatic extraction were as follows:adding amount of lipase was 0.015 g·100 mL-1 ,adding amount of amylase was 0.035 g·100 mL-1 ,and adding papain 0.075 g·100 mL-1 ,inclu-ding the impact of orthogonal experiment factors for amylase>protease>lipase.The best extraction rate of water-soluble dietary fiber was 1.285%.The extraction of sweet potato leaves and stems of soluble dietary fiber in high pu-rity,water holding capacity was 787%,the swelling force was 4.10 mL·g-1 ,the product had good quality.关键词
