Description

A kind of quick method for preparing pulp-water
Technical field
The present invention relates to a kind of fermented vegetables products, more particularly to a kind of quick method for preparing pulp-water.
Background technology
Pulp-water is a kind of distinctive fermented vegetables products in NORTHWEST CHINA area, and its generations is with a long history, over the past thousands of years depth by Broad masses of the people like.Pulp-water is mainly using seasonal vegetable or wild vegetables as raw material, generally with noodle soup or farmers''s tradition " sauerkraut introduction " start fermentation.Without any seasoning in fermentation, fermented type is based on less salt spontaneous fermentation.Fermentation time Different with temperature difference, usually 48 ~ 72 hours, its fermentation process had acetic fermentation, alcoholic fermentation and lactic fermentation concurrently, and Based on lactic fermentation.There is studies have shown that fermented vegetable during the fermentation, lactic acid bacteria mainly utilizes the soluble battalion in vegetables Support material to be metabolized, it does not possess the enzyme system of decomposition of cellulose and aminosal, and whole fermentation process neither destroys vegetable Existing protein and amino acid in dish, and vegetable plant cells tissue is not destroyed.With the exception of this, the generations such as the lactic acid produced in fermentation Thank to thing and also have the double action for improving local flavor and anti-corrosive antibacterial.Due to having above-mentioned advantage concurrently so that pulp-water not only clean taste, taste Road is delicious, also nutritious, contains Multiple components, vitamin, amino acid and carrotene and mineral element etc..Traditional Chinese Medicine is recognized Have for, pulp-water overcome difficulties be tired of, regulating QI of the middle-JIAO, conditioning viscera, appetizing are quenched the thirst, the effect of diuresis water flowing, and modern medicine finds it Also there are other effects, such as lowering blood pressure and blood fat, reduction blood cholesterol levels, prevention cardiovascular and cerebrovascular disease.But it is made at present It is mostly that Homemade is used by oneself as technique, product health is difficult to ensure that quality is not sufficiently stable, and product can not be standardized, consumption office Domain property is strong so that the slower development of pulp-water.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of low quick side for preparing pulp-water of simple to operate, cost Method.
To solve the above problems, a kind of quick method for preparing pulp-water of the present invention, comprises the following steps:

(2) the activation of strain:Compound bacteria is connected on the seed culture medium according to 1% ~ 10% inoculum concentration, in 37 DEG C of fermentations 24h, the pulp-water strain after being activated;The compound bacteria is mixed by isometric saccharomycete and lactic acid bacteria;
(3) the preparation of leavening:The pulp-water strain after the activation is made an addition into the seed according to 1% ~ 10% inoculum concentration to train Support in base, 3d is cultivated in 30 DEG C, after culture terminates, freezed in vacuum freeze drier, produce leavening;
(4) the preparation of auxiliary material:Flour is slowly added to after water is boiled, is slowly stirred, it is cold after stopping heating after starch gelatinization But auxiliary material is produced to room temperature;The weight ratio of the flour and water is 1:50~100;
(5) the preparation of pulp-water:By weight, 100 are added to after 1 ~ 3 part of freeze-dried vegetable powder and 5 ~ 15 parts of auxiliary materials being mixed The boiling water of part, adds 1 ~ 3 portion of leavening after cooling, 24 ~ 48h is then placed under the conditions of 30 DEG C, pulp-water is produced.
The step (3) in lyophilisation condition refer to temperature be -45 DEG C ~ -55 DEG C, vacuum be 10 ~ 20Pa, the time be 24 ~ 48h。
The present invention has advantages below compared with prior art:
Raw material of the present invention is easy to get, easy to operate, not only gained pulp-water steady quality, nutrient health, and production marketing process without Strict refrigerated condition is needed, the nutritive value and functional characteristic of pulp-water can also be possessed after recovery;At the same time it can also obtain pulp-water Microbial inoculum, has filled up the blank in China's pulp-water market.
