Description

Chick-pea acidified milk and preparation method thereof
Technical field
The present invention relates to food processing technology fields, and in particular to a kind of chick-pea acidified milk and preparation method thereof.
Background technique
Chick-pea (Cicer arietinum Linn) originate from western part of Asia and Middle East, be in the world most it is ancient and One of leguminous plant most planted extensively, is mainly distributed on warm in the world and compared with arid area, and yield occupies world beans Three.Chick-pea belongs to the barren-resistant crop of drought resisting, requires soil not tight, and it is deep to be typically chosen in soil layer, middle fertility plot, hawk Garbanzo is significant for northwest China, southwest and other vast arids, the exploitation of semiarid zone;Moreover, chick-pea is sought Form point complete, seed contains protein 23.0%, carbohydrate 63.5%, fat 5.3%, dietary fibre also rich in, micro Element and vitamin etc.;Important sources of the chick-pea as major economic crops and green plants albumen in Food Legume, Development prospect is had a vast market, the plant base acidified milk that chick-pea is finish-machined to that there is high added value and demand to increase severely is produced Product not only can improve the general level of the health of the people, and environmentally friendly with the kind of rich functionality food.
Chick-pea fermented dairy product is formed by the raw material effect of undergoing microbial fermentation of chick-pea, and Chickpea Protein passes through The restricted hydrolysis for the extracellular protease that microorganism generates, increases active peptide and amino acid in chick-pea acidified milk system and contains Amount, nutritive value greatly improves, amino acid rich in, isoflavones, vitamin, dietary fiber etc., have it is anti-oxidant, Anti-ageing equal functional characteristics, are suitble to eating for various people.However, existing chick-pea acidified milk has still had mouthfeel not at present It is good, texture is bad, produce subacidity defect.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of chick-pea acidified milks and preparation method thereof, it is intended to solve existing Chick-pea acidified milk mouthfeel is bad in technology, texture is bad, produces the technical issues of subacidity.
Inventor has found in long-term research practice, due to chick-pea acidified milk constituent and gel structure with it is general Logical fermentation cow's milk is different, in physicochemical property and mouthfeel compared with common fermentation dairy product, there is biggish defect, olecranon Legumin is unfavorable for the growth and breeding of traditional yogurt leavening streptococcus thermophilus and lactobacillus bulgaricus as vegetable protein, Because lactose is free of in chickpea milk, and sucrose and glucose content are also few, if with common ferment agent for sour milk streptococcus thermophilus With bulgaria lactobacillus fermentation chickpea milk then there are profitable strain growth is not vigorous enough, subacidity is produced, mouthfeel is bad etc. Disadvantage.
Inventor further study show that, Chickpea Protein is after enzymolysis processing, the small-molecular peptides and free ammonia of generation Although base acid can be utilized by growth of probiotics, with the raising of Chickpea Protein hydrolysis degree, often along with bitter taste It generates, this is primarily due to the exposure of chick-pea peptide chain C or N-terminal hydrophobic amino acid, and higher enzyme additive amount can be in short-term The interior length for causing Chickpea Protein peptide chain extremely shortens, and is then unfavorable for the formation of gel network structure compared with short peptide chain.Cause How this, the hydrolysis of appropriateness is carried out to chickpea milk ingredient, while so that it is conducive to growth of probiotics, and improves hawk The physiological activity of garbanzo acidified milk improves its texture, rheology and gel characteristic and is of great significance.Specifically, for upper Problem is stated, the present invention utilizes the endopeptidase activity of protease, the protein in Mild degradation chick-pea, and combines using protease Alpha-amylase and saccharifying amylase are carried out appropriate hydrolysis to chickpea milk ingredient jointly, are acted on using its coordinated enzymatic hydrolysis, with It prepares texture and flavor has both the chick-pea acidified milk of high-quality.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
Design a kind of preparation method of chick-pea acidified milk, comprising the following steps:

(3) protease, alpha-amylase and carbohydrase are added in gained soya-bean milk, 30min~2h are kept the temperature at 30~50 DEG C, then press After 8%~10% sugaring of dry chick-pea weight, sterilizing mixed liquor, wherein protease additive amount is 2000U~6000U/ grams of egg It is white, alpha-amylase additive amount be 10000U~30000U/ grams of starch, carbohydrase additive amount be do chick-pea weight 0.1%~ 0.5%;
(4) by 0.2%~0.6% inoculating starter in step gained mixed liquor upwards of dry chick-pea quality, 8 are fermented at 38~42 DEG C ~13h, at 2~10 DEG C refrigerate 12~for 24 hours,.
Design the preparation method of another chick-pea acidified milk, comprising the following steps:
(1) 10~15h of chick-pea is impregnated with clear water, pulls chick-pea draining out;
(2) it is beaten after mixing chick-pea and 70~90 DEG C of water by weight 1:5~10, filters to obtain soya-bean milk;
(3) color protection treatment will be carried out after yam slices, add water by the mass ratio that Chinese yam and water are 1:0.4~0.6, grind Chinese yam Slurry, then gained Chinese yam pulp, protease, alpha-amylase and carbohydrase are added in the soya-bean milk, keep the temperature 30min at 30~50 DEG C ~2h, then mixed liquor is obtained after pressing 8%~10% sugaring of dry chick-pea weight, sterilizing;Wherein, the additive amount of Chinese yam pulp is pure soya-bean milk The 50~80% of quality, protease additive amount be 2000U~6000U/ grams of albumen, alpha-amylase additive amount be 10000U~ 30000U/ grams of starch, carbohydrase additive amount are the 0.1%~0.5% of dry chick-pea weight;
(4) by 0.2%~0.6% inoculating starter in step gained mixed liquor upwards of dry chick-pea quality, 8 are fermented at 38~42 DEG C ~13h, at 2~10 DEG C refrigerate 12~for 24 hours,.
It preferably, is that 0.5% sodium bicarbonate solution substitutes clear water immersion olecranon with mass fraction in the step (1) Beans.
Preferably, in the step (2), weight ratio is beaten after the chick-pea and 85 DEG C of water mixing of 1:8, then use yarn Cloth filters to obtain soya-bean milk.
Preferably, in the step (3), proteinase activity power is 100,000 U/g;Alpha-amylase enzyme activity is enzyme activity 4 Ten thousand U/g.
