Abstract

The invention relates to a preparing method for a beverage, and in particular relates to a method for preparing a health-protection soybean beverage by using defatted soybean powder. The preparing method comprises the following steps: weighing the defatted soybean powder, adding water, uniformly stirring, adjusting the PH to 4-4.5, performing sterilization, cooling to 45-50 DEG C, adding acid proteinase for hydrolysis for 6-8 hours, then boiling, cooling to 28-30 DEG C, inoculating asergillus cristatus raper and fennell, fermenting for 30-36 hours, performing centrifugation to obtain supernate, and performing blending, filling and sterilization on the supernate to obtain a finished product. The health-protection soybean beverage takes the defatted soybean powder as a raw material; under the enzymolysis action of acid proteinase and the fermentation action of the aspergillus cristatus raper and fennell, proteins in the defatted soybean powder are degraded into protein peptides, so that the respective advantages of an enzyme method and a fermentation method are effectively completed; the nutrition is rich, and the effect is outstanding; furthermore, the prepared beverage tastes good and does not have bitterness and peculiar smell.

Description

The preparation method of soybean health care drink

Technical field

What the present invention relates to is a kind of preparation method of beverage, specifically utilizes defatted soy flour to make the method for soybean health care drink.

Background technology

Soybean contains rich in protein, carbohydrate, vitamin, mineral matter etc., is the important sources of good protein in China resident meals.In soybean, protein content is about 35%-40%, except methionine, the composition of all the other essential amino acids is similar to animal protein with ratio, particularly be rich in the lysine that grain protein lacks, it is the natural ultimate food with grain protein complementation, in soybean, also contain abundant phosphorus, iron, calcium etc., all obviously more than cereal, Cobastab in soybean ₁, Cobastab ₂also doubly most than cereal with the B family vitamin content such as nicotinic acid, and the carrotene that contains some and abundant vitamin E.Although the protein in soybean is nutritious, but because soybean protein is macromolecular substances, there is the shortcomings such as not soluble and non-digestible, make its nutritive value beat greatly button, how to overcome the shortcomings such as soybean protein is not soluble and non-digestible, increase its nutritive value, become the focus of current research.

If utilize bionic method, soybean protein is degraded into small-molecule peptide, not only can overcome the soluble and not non-digestible shortcoming of soybean protein, can also increase many physiological functions, because that Soybean Peptide has is anti-oxidant, hypotensive, replenish the calcium, delay senility, strengthen immunity, promote the several functions such as mineral absorption.

Summary of the invention

The object of the present invention is to provide a kind of taking defatted soy flour as prepared using enzyme process and microbe fermentation method combine and make the method for soybean health care drink.

The object of the present invention is achieved like this:

Take the defatted soy flour of certain mass, add the water of 10-15 times of quality, stir, PH is adjusted to 4-4.5,121 DEG C of sterilizing 20-30 minute, cool to 45-50 DEG C, add the ratio of 80-100 unit to add acid protease in every gram of raw material, at 45-50 DEG C of Water Under solution 6-8 hour, then boil 10-15 minute, cool to 28-30 DEG C, press the inoculum concentration inoculation aspergillus cristatus seed liquor of 5-10%, at the shaking table top fermentation 30-36 hour of 150-180rpm, 28-30 DEG C, centrifugal clear liquid, clear liquid gets product through allotment, filling, sterilizing again.

The present invention also comprises following feature:

The preparation method of described aspergillus cristatus seed liquor is: get 6-10B _xbrewer's wort, 121 DEG C of sterilizing 15-20 minute, are cooled to 28-30 DEG C, and inoculation aspergillus cristatus is cultivated 18-20 hour on the shaking table of 150-180rpm, 28-30 DEG C.

Soybean health care drink of the present invention is taking defatted soy flour as raw material, successively by the enzymolysis of acid protease and the fermentation of aspergillus cristatus, the PD in defatted soy flour is become to protein peptides, effectively combine enzyme process and fermentation method separately advantage, not only nutritious, effect is outstanding, and the beverage mouthfeel making is good, without bitter taste, free from extraneous odour.

Specific embodiments

The bacterial strain aspergillus cristatus CICC2422 that the present invention adopts purchases in Chinese industrial microorganism fungus kind preservation administrative center.

Get 8B _xbrewer's wort, 121 DEG C of sterilizings 20 minutes, are cooled to 30 DEG C, and inoculation aspergillus cristatus is cultivated and within 20 hours, is obtained aspergillus cristatus seed liquor on 150rpm, the shaking table of 30 DEG C.

Take the defatted soy flour of certain mass, add the water of 15 times of quality, stir, PH is adjusted to 4.5,121 DEG C of sterilizings 20 minutes, cool to 50 DEG C, add the ratio of 90 units to add acid protease in every gram of raw material, 50 DEG C of Water Under solutions 7 hours, then boil 15 minutes, cool to 30 DEG C, by 10% inoculum concentration inoculation aspergillus cristatus seed liquor, in 150rpm, the shaking table top fermentation 32 hours of 30 DEG C, centrifugal clear liquid, clear liquid gets product through allotment, filling, sterilizing again.

Claims

1. the preparation method of soybean health care drink, is characterized in that being prepared from through following process:

(1) get 6-10B _xbrewer's wort, 121 DEG C of sterilizing 15-20 minute, are cooled to 28-30 DEG C, and inoculation aspergillus cristatus is cultivated and within 18-20 hour, is obtained aspergillus cristatus seed liquor on the shaking table of 150-180rpm, 28-30 DEG C;

(2) take the defatted soy flour of certain mass, add the water of 10-15 times of quality, stir, PH is adjusted to 4-4.5,121 DEG C of sterilizing 20-30 minute, cool to 45-50 DEG C, add the ratio of 80-100 unit to add acid protease in every gram of raw material, at 45-50 DEG C of Water Under solution 6-8 hour, then boil 10-15 minute, cool to 28-30 DEG C, press the inoculum concentration inoculation aspergillus cristatus seed liquor of 5-10%, at the shaking table top fermentation 30-36 hour of 150-180rpm, 28-30 DEG C, centrifugal clear liquid, clear liquid gets product through allotment, filling, sterilizing again.
