Description
Technical field
The present invention relates to bean product processing technique fields, and in particular to one kind being based on super-pressure-limited enzymatic hydrolysis technology system
The method of standby desensitization millet type soy milk powder.
Background technology
Contain abundant nutriment, wherein carbohydrate containing 70% or so, 8-16% containing protein in cereal；It is fatty
Relatively low 1-2%, 1.5-3% containing inorganic salts, while cereal is also the important sources of B family vitamin in human diet.And in cereal egg
But lack lysine in white matter, but be rich in lysine in the protein of beans；The cereal such as corn and millet are rich in phenylpropyl alcohol ammonia
Acid and methionine, and content is all relatively low both in soybean.Therefore cereal is mixed into feed with beans, it can make up for each other's deficiencies and learn from each other,
Keep mixed essential amino acid mutual ratios more rational.This grain type soy milk powder is popular currently on the market.
Currently, the preparation soy milk powder application of conventional wet technique is wider, but soy milk powder made from conventional process techniques has cause
Quick property, allergic protein are mainly glycinin, beta-conglycinin etc..Currently, enzymolysis is to reduce soybean sensitization most to have
The method of effect, but the major defect digested is incomplete destruction epitope and forms strong bitter taste, is unfavorable for soy milk powder and exists
Marketing both domestic and external.
