Embodiment 1

[0027] The preparation method of novel modified bean dregs dietary fiber-protein hypoglycemic formula powder comprises the following steps:

[0028] (1) Select fresh bean dregs, fully grind them in a grinder, pass through a 80-100 mesh sieve, and obtain bean dregs foam for later use;

[0029] (2) Add 3 times the volume of deionized water to the above-mentioned bean dregs, stir evenly and pretreat in a high-voltage pulsed electric field, and then use vacuum concentration technology to concentrate the pretreated slurry to 1 / 3 of the original volume, and then Carry out drying treatment in the drying machine, obtain the pretreated bean dregs for subsequent use;

[0030] (3) Add the above-mentioned pretreated bean dregs into n-hexane, heat and stir at a constant speed for 2 hours, then centrifuge in a high-speed centrifuge, collect the precipitate, repeat the above step 3 times, and dry the precipitated bean dregs in an oven to obtain defatted bean dregs for later use ;

Abstract

The invention provides a preparation method of a novel modified soybean dreg dietary fiber-protein formula powder for lowering blood sugar, and relates to the technical field of soybean byproduct processing. The preparation method of the modified soybean dreg dietary fiber-protein formula powder for lowering blood sugar mainly comprises the following steps: soybean dreg grinding, high-voltage pulse electric field pretreatment, degreasing, novel airflow spray explosion technology treatment, blending, humidifying, freezing, crushing and drying. The method overcomes the defects of the prior art,and effectively solves the problems of residue waste of soybean products such as tofu, soybean milk, bean flour and soybean oil and environmental pollution caused by the waste. Besides, the obtained product has good water-holding properties and expansibility, has certain satiety and blood sugar-reducing functions after being eaten, and is suitable for sub-healthy people with hyperglycemia and obesity. Meanwhile, the product also has the advantages of high stability, simple process and low production cost.

Description

technical field [0001] The invention relates to the technical field of soybean by-product processing, in particular to a method for preparing a novel modified bean dregs dietary fiber-protein hypoglycemic formula powder. Background technique [0002] Okara is rich in dietary fiber. Studies have found that the combination of dietary fiber and okara protein in okara has a hypoglycemic effect. At present, the methods for improving the quality characteristics of bean dregs mainly include chemical methods, biological methods and physical methods. The chemical method to extract water-insoluble dietary fiber has poor flavor and color of the product, and the production process is easy to cause pollution to the product and the environment. Membrane separation method cannot prepare insoluble dietary fiber. [0003] The new airflow spray explosion technology is to place the raw materials in a high-temperature, high-pressure digitally controlled vertical continuous gas explosion mach...
