Abstract

The invention discloses a method for reducing starch digestibility and application thereof, and belongs to the technical field of enzyme engineering. The invention provides a method for reducing the starch digestibility, and the method can be used for preparing resistant starch and has very high production efficiency. By utilizing the method, a glycogen branching enzyme ChlGBE is added into a starch solution to be modified for 6 hours, so that the content of resistant starch in the starch solution can be as high as 35.06% and is increased by 9.75% compared with that of an unmodified starch solution. By utilizing the method, a glycogen branching enzyme HosGBE is added into a starch solution to be modified for 8 hours, so that the content of resistant starch in the starch solution can be ashigh as 47.36% and is increased by 22.05% compared with that of an unmodified starch solution. By utilizing the method, a glycogen branching enzyme VvGBE is added into a starch solution to be modifiedfor 10 hours, so that the content of resistant starch in the starch solution can be as high as 51.4% and is increased by 26.09% compared with that of an unmodified starch solution.

Description

Technical field

[0001] The invention relates to a method and application for reducing starch digestibility, and belongs to the technical field of enzyme engineering. Background technique

[0002] Starch is the main carbon storage and energy storage polysaccharide in nature. It can provide 70-80% of the energy for the human body and is the most important source of dietary energy for the human body. According to different digestibility, starch can be divided into three types, namely fast digestion starch (RDS), slow digestion starch (SDS) and resistant starch (RS). Among them, fast-digestible starch (RDS) refers to the starch that is completely digested and absorbed in the small intestine, slow-digested starch refers to the starch that is completely digested and absorbed in the small intestine 20 to 120 minutes, and resistant starch refers to the starch that cannot be digested and absorbed by the small intestine after 120 minutes. starch.

[0003] Studies have shown that due to its...
