Abstract

The invention discloses a production method of solidifying type fermented soy milk and stirring type fermented soy milk. The production method comprises the following steps that soybean is ground to form soybean milk; a seed agent is prepared; soy milk is subjected to fungus inoculation and fermented; and a product is packaged, warehoused and subjected to after-ripening. The production method takes the soybean as a raw material, and the viable organism soy milk product is obtained by fermentation of various lactobacillus and yeast probiotics according to a modern scientific theory; the product has the advantages of mellow perfume, delicate taste, high viable organism density and rich nutrition; in addition, the soy milk produced by the method has double health care functions of a soybean product and a probiotic viable organism product; and the production method of the soy milk has very high practical application significance.

Description

The production method of a kind of coagulating type fermented soybean milk and agitating type fermented soybean milk
Technical field
The invention belongs to soy milk production fermentation field, relate in particular to the production method of a kind of coagulating type fermented soybean milk and agitating type fermented soybean milk.
Background technology
Soya-bean milk, since the Huainan king Liu An of Western Han Dynastry invention, has had the history of more than 1900 year, and it is welcome by popular as a kind of protein drink.But the soya-bean milk that traditional manufacture craft obtains can not meet popular healthy consumption demand.Fermented soybean milk, from the Qing Dynasty, just produce, but its production method mostly is the bacterial classification of spontaneous fermentation, and at present, acid mung bean milk is only fraction area consumer's acceptance such as Beijing, but, because of its local flavor problem, other various places acceptance levels are very little.These are all to hinder the reason that fermented soybean milk standardizes on a large scale and produces.
Although China is the area of origin of soya-bean milk, the manufacture craft of soya-bean milk lags far behind U.S., Japan and Korea S., and especially probiotics fermention soymilk will lag behind these countries more than 20 year, the exploitation of soya-bean milk (soymilk), and Japan and the United States, Korea Spro march at the forefront of the world.By the domestic history just had about 20 years of the further investigation of lactobacillus-fermented soya milk product.
In recent years, many researchers of China, according to modern scientific theory, have also carried out many research to this, especially after 2006, for experiment provides abundant theoretical foundation.Fermented bacterium is varied, as bacillus bulgaricus, streptococcus thermophilus, Bifidobacterium, rhamnose bacillus, Bacillus casei etc.
Yet how the selection of people to probiotics fermention soymilk leavening, remove the ANFs produced in slurrying and sweat and make up the good solution that problem that in soya-bean milk, vitamin content is few is not still looked for.
Summary of the invention
The purpose of the embodiment of the present invention is to provide the production method of a kind of coagulating type fermented soybean milk and agitating type fermented soybean milk, is intended to solve and how removes the ANFs produced in slurrying and sweat and make up the few problem of vitamin content in soya-bean milk.
The embodiment of the present invention is achieved in that the production method of a kind of coagulating type fermented soybean milk and agitating type fermented soybean milk, and this production method comprises the following steps:
Adopt soya bean to grind soya-bean milk;
Prepare seed forming agent;
Inoculum fermented soymilk;
The after-ripening of packing of product warehouse-in.
The concrete steps that further, adopt soya bean to grind soya-bean milk are:
Choosing, without the full soya bean of worm, is 0.1~0.5%NaHCO by the mass concentration of 2.9~3.3 times of quality 3solution, adjust pH to 7.5~8.5, at 80 ℃~85 ℃ of temperature, soak 6~8h, soaks the rear dry beans of end and be about 1: 2.88 with wet beans ratio;
Adjusting beans water ratio is 1: 8~14, adopts soy bean milk making machine by the soya bean defibrination;
Homogeneous, homogenization pressure is 15~25Mpa for the first time, homogenization pressure is 40~50Mpa for the second time; 50~60 ℃ of homogenizing temperatures.
Boiling, mashing off 10~15min.
Remove by filter bean dregs with 150~200 eye mesh screens;
112~115 ℃, 15~25min, sterilizing.
The method that further, seed forming agent is prepared is:
In the soya-bean milk that is 60~80% in volume ratio by Lactobacillus rhamnosus, lactobacillus acidophilus, lactobacillus bulgaricus, cultivate, remaining 20~400% is the degreasing recombined milk; Bacillus bifidus and yeast are cultivated in pure soya-bean milk.Cultivation temperature is 35~42 ℃, and the time is 4~8h.
Further, inoculum fermented method is:
By cultured Lactobacillus rhamnosus, lactobacillus acidophilus, lactobacillus bulgaricus, two qi lactobacillus, yeast according to 1: 1: 1: 1: 1 to 5: 5: 5: the ratio of 5: 1 was carried out composite, according to always connecing the ratio of bacterium amount 2~5%;
37~42 ℃, ferment at constant temperature.
Further, the coagulating type fermented soybean milk adds the auxiliary material gelatin after mashing off slagging-off, addition is 0.1~0.3%.
Further, to add stabilizing agent anti-acid core methylcellulose after fermentation be CMC to the coagulating type fermented soybean milk, water dissolves, 121 ℃, add soya-bean milk after 15~25mi sterilizing, addition is 0.2~0.4% of soya-bean milk gross mass, does not need to stir.
Further, coagulating type fermented soybean milk sterile filling after having connect bacterial classification.
Further, after products obtained therefrom packing, the condition of warehouse-in after-ripening is 2~4 ℃, after-ripening 12~24h.
The present invention be take soybean as raw material, according to modern scientific theory, and the viable bacteria soya milk product obtained with various lactobacillus, yeast probiotics fermention.Product has strong and brisk in taste, delicate mouthfeel, the advantage such as viable bacteria density is high, nutritious.There is soybean prod and the dual health care of probiotics viable bacteria product.The soymilk of these research and development has very strong practical application meaning.
