Abstract

The invention discloses secoisolariciresinol diglucoside hydrogel based on soybean protein isolate and carrageenan and a preparation method of the secoisolariciresinol diglucoside hydrogel, and belongs to the technical field of food processing. The method comprises the following steps: (1) dissolving soybean protein isolate powder in water to obtain a hydrated protein solution, then heating to obtain a protein aggregate, and cooling for later use; (2) mixing a secoisolariciresinol diglucoside solution with the protein aggregate, and then adding carrageenan to obtain a pre-gel solution; and (4) adding gluconic acid-delta-lactone into the pre-gel solution to obtain the lignan hydrogel based on the soybean protein isolate and the carrageenan. The gel prepared by the method disclosed by the invention has good water binding capacity, viscoelasticity and capability of controlling the release of lignan.

Description

Technical field

[0001] The present invention relates to a hydrogel and preparation method thereof based on soybean separation protein and karamis, belonging to the field of food processing technology. Background technique

[0002] Linen phenol is a class of biological active ingredients in flaxseed, and the study shows that linen phenol needs to be converted into animal oriented with intestinal microbial metabolism to be absorbed by human body, with anti-cancer, prevention of osteoporosis, prevention Cardiovascular disease, anti-aging, etc. Many bioactive molecules include wood phenol, due to factors such as environmental conditions (e.g., light, temperature and oxygen) or gastrointestinal (digestive enzymes, pH, etc.) during the food processing, There is a problem after oral administration, and there is a problem of stability and low bioavailability.

[0003] The hydrogel is formed by crosslinking by hydrophilic macromolecules in aqueous solution, with a characteristic of a thre...
