preparation example Construction

[0021] A rich vitamin B 12 The preparation method of instant bean powder, the method comprises the following steps:

[0022] (1) Take commercially available soybeans and add distilled water at a ratio of 1:5, soak for 12 hours, refine the pulp, and put them in a water bath for enzymolysis. The enzymolysis conditions are: enzymolysis temperature 55°C, enzymolysis time 2h, pH value maintenance At 9.0, the amount of flavor protease added is 0.2-0.6%, and after the enzymolysis is completed, boil for 5 minutes to kill the enzyme and sterilize;

[0023] (2) Weigh 1~5% (w / v) vitamin B 12 Powder, added to the soymilk after enzymatic hydrolysis, and then added konjac powder, functional oligosaccharides, maltodextrin, and modified chitosan in equal proportions to prepare;

[0024] (3) Use a cavitation jet homogenizer for processing, the processing conditions are: temperature 25°C, pressure 0.1MPa, processing time 20-40min;

[0025] (4) Add 0.3-0.9% modified soybean lecithin in the so...

Abstract

The invention discloses a preparation method of instant bean flour rich in vitamin B12, and belongs to the field of food processing. The preparation method mainly comprises the following steps: (1) performing soybean soaking, performing grinding, performing enzymolysis and performing enzyme deactivation; (2) adding vitamin B12 powder into soybean milk, adding konjaku flour, functional oligosaccharide, maltodextrin and modified chitosan in equal proportion, and performing blending; (3) performing treating by using a cavitation jet homogenizer; (4) adding modified soybean phospholipid; and (5) performing spray drying treatment to obtain the instant bean flour rich in vitamin B12. The solubility and beany flavor of the bean flour are improved by utilizing enzymolysis, soybean lecithin and cavitation jet flow, the vitamin B12 is contained, and the bean flour rich in vitamin B12 is prepared. The bean flour prepared by the method is pure in taste, good in solubility and free of caking, and can be eaten by people needing to supplement vitamin B12.

Description

technical field [0001] The invention belongs to the field of food processing, and mainly relates to a vitamin B-rich 12 The preparation method of instant soybean powder. Background technique [0002] Numerous nutraceutical compounds (vitamins and phenolic compounds) have some beneficial effects on reducing the risk of chronic diseases and promoting human health. However, most nutraceuticals have low oral bioavailability due to their short residence time in the gastrointestinal tract or low intestinal permeability, limiting their potential health benefits. Vitamin B 12 is a typical example. Vitamin B 12 Also known as cobalamin, is a naturally occurring organometallic compound that is an important water-soluble vitamin for human health. Vitamin B 12 The recommended daily intake is 2.4 μg. But vitamin B 12 The absorption pathway is complex. First, vitamin B 12 It is separated from the food matrix by gastric digestion and then combined with gastric intrinsic factor. T...
