Problems solved by technology

[0002] Dietary fiber is a kind of plant edible part or similar carbohydrates that cannot be absorbed by the small intestine of the human body, but can be completely or partially fermented in the large intestine. Potato residue, accounting for about 10%-14% of the raw material, is a good resource for the production of dietary fiber. However, at present, the chemical method is the main method for extracting dietary fiber at home and abroad. This process is simple and the input cost is low. The physical and chemical properties and physiological functions of fiber products are significantly affected. The extracted dietary fiber has poor physiological activity and low purity, which affects the function of dietary fiber products.

Embodiment Construction

[0020] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0021] The technological method in extracting sweet potato waste residue comprises the following steps:

[0022] (1) Preparation of potato residues: After crushing potatoes, filter them with 6 layers of gauze and wash repeatedly to remove starch to obtain potato residues.

[0023] (2) Cleaning and removing impurities: washing the filtered potato residues to remove impurities in the potato residues.

[0024] (3) drying.

[0025] (4) Ultra-fine grinding: Carry out colloid milling on the potato residue twice, the first colloid mill fineness is 80 mesh; The feed liquid is subjected to high-pressure homogenization operation to further refine the feed liquid, and the pressure of the homogenizer is 25-30MPa.

[0026] Ultrafine pulverization breaks the larger incompatible dietary fiber molecular chains to form soluble...

Abstract

The invention discloses a method for extracting high-activity sweet potato dietary fibers, which comprises the following steps of: removing impurities, drying, crushing, adding water and blending, and then adopting a process of combining a physical screening process, an enzyme extraction process and a superfine grinding process, so that the high-concentration low-calorie high-activity sweet potato dietary fibers can be successfully prepared from sweet potato starch processing waste residues, and the sweet potato dietary fibers are good in mouth feel, low in calorie and high in activity. The purity is high.

Description

technical field [0001] The invention relates to the field of dietary fiber processing, in particular to a method for extracting high-activity sweet potato dietary fiber. Background technique [0002] Dietary fiber is a kind of plant edible part or similar carbohydrates that cannot be absorbed by the small intestine of the human body, but can be completely or partially fermented in the large intestine. Potato residue, accounting for about 10%-14% of the raw material, is a good resource for the production of dietary fiber. However, at present, the chemical method is the main method for extracting dietary fiber at home and abroad. This process is simple and the input cost is low. The physical and chemical properties and physiological functions of fiber products are significantly affected. The extracted dietary fiber has poor physiological activity and low purity, which affects the function of dietary fiber products. Contents of the invention [0003] The purpose of the inven...
