A kind of multi-enzyme modified microcrystalline yam powder with laxative effect and preparation method

Abstract

The present invention discloses multi-enzyme-modified microcrystalline Chinese yam powder for relaxing bowel and a preparation method thereof. The preparation method includes the following steps: (1) weighting whole Chinese yam powder, adding acetic acid-sodium acetate buffer (with pH being 5.2) into the whole Chinese yam powder and evenly mixing the mixture; and stirring the mixture to obtain suspension; (2) adding alpha-amylase into the suspension and stirring the suspension; adding pullulanase into the suspension and stirring the suspension; cooling the suspension to 4 DEGC and standing; and heating the suspension in boiling water bath to inactivate enzymes to obtain enzymatic hydrolysate; and (3) washing the enzymatic hydrolysate with aqueous ethanol solution until the supernatant is clear and transparent, filtering the enzymatic hydrolysate, and drying, crushing and sieving precipitates. Through the preparation method, the Chinese yam powder is modified by two biological enzymes, and the Chinese yam powder has significant changes in the aspects of micro-morphology and physical and chemical properties of. The multi-enzyme-modified microcrystalline Chinese yam powder can prevent and relieve constipation, and pharmacological experiments prove that the multi-enzyme-modified microcrystalline Chinese yam powder can improve the intestinal propulsion, and has a significant effect in relaxing bowel.

Description

Technical field [0001] The invention belongs to the field of health food, and particularly relates to a preparation method of multi-enzyme modified microcrystalline yam powder with laxative effect.
