Embodiment 1

[0027] A method of preparation based on soyphenol hydrogel based on soybean separation protein and karawick, the specific steps are as follows:

[0028] (1) Preparation of soy protein separation protein solution: It is called 0.84 g of soy separation protein (SPI) in 9 ml of ultra-pure water, and magnetically stirred overnight, so it is sufficiently hydrated;

[0029] (2) Preparation of soy separation protein aggregates: Place the hydrated protein solution obtained in step (1) at an 80 ° C constant temperature water bath heating for 30min, cooled to room temperature with water, placed at 4 ° C refrigerator;

[0030] (3) Preparation of mixed solution of soybean separation protein aggregates - taking: 52.5 mg of linen phenol powder is dissolved in 10 ml of ultra-pure water to obtain a 5.25 mg / ml of phenol solution, take 1 ml of wood phenolin solution The syringe is added dropwise to the protein aggregation solution (about 10 mL) obtained by step (2), and the magnetic force is stir...

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...
