A kind of production method of fruit vegetable bean curd
Technical field
The present invention relates to a kind of production methods of fruit vegetable bean curd, more particularly to the protein emulsion gel containing juice
Production method.
Background technique
Bean curd is the maximum traditional food of China's volume of production and marketing, is that soybean protein is bound to each other to form under coagulator effect
Gel products with three-dimensional net structure.The manufacture craft of traditional bean curd generally comprises following steps: soybean screening, washing,
It impregnates, rinses, defibrination, filter to obtain soya-bean milk, mashing off, coagulator, compression moulding after crouching brain squeezes is added in point slurry after temperature adjustment.?
On the basis of guaranteeing nutrition, it is abundant, beautiful how to make the color of bean curd, and supplement other nutrients, such as: vitamin, thus
Increase the kind of bean curd and increase the desire to buy and appetite of consumer, is always problem to be solved.Currently, people attempt
In the manufacture craft of traditional bean curd, using soybean as raw material, after a series of processing, point slurry, such as: Salt treatment gel is added
Magnesium chloride, gypsum etc.;Acid induction gel, is added glucolactone etc.;Vegetable juice is added before slurry, fruit vegetable bean curd is made.But
It is this kind of bean curd using still limited.To find out its cause, in existing juice bean curd, curd gel short texture, gel net
Network is bigger, and vegetable juice is easily separated from bean curd when heating and water are impregnated;In addition, above-mentioned fruit vegetable bean curd induces gel for acid
Occasion the problems such as there is also weak flavors.Again, this kind of bean curd production needs mostly using soybean as raw material by immersion, defibrination, pressure
The processes such as squeezing, it is not only time-consuming, but also generate a large amount of waste water.
Summary of the invention
The object of the present invention is to provide a kind of fruit vegetable bean curd and preparation method thereof, which not only shortens the production of bean curd
Time saves water, and product of the present invention has the characteristics that juice without free, in beautiful color, quality is close, strong and brisk in taste, this
It will be enlarged by the application of bean curd.
The technical scheme adopted by the invention is that:
Low temperature edible bean cake is crushed, crosses 60 meshes by the first step, is that 1.2 ~ 1.5:10 is scattered in steaming by solid-to-liquid ratio
In distilled water, protein dispersion is obtained;In the solid-to-liquid ratio solid dosage be kilogram, volume unit be rise;
Second step, protein dispersion are handled 5-10 minutes in 80-90 DEG C of heating water bath, are cooled to 50-60 DEG C later;
Third step is heated resulting soybean protein dispersion liquid through second step and is stirred with volume ratio 1:0.10-0.20 and vegetable oil
Make pre- homogenization after mixing mixing, wherein revolving speed is 10000 ~ 12000 revs/min, and the time is 2 ~ 3 minutes, and it is slightly newborn to obtain protein
Liquid;The vegetable oil is soybean oil or corn oil;Pre-emulsification can promote vegetable oil to be preferably scattered in soybean protein dispersion liquid
In, it can be ensured that reach better emulsifying homogeneous effect, obtains the ideal protein lotion of property.
4th step makees high-pressure homogeneous processing twice to the thick lotion of protein using high pressure homogenizer, and wherein homogenization pressure is
20 ~ 40 megapascal, the thick lotion cellulite of protein is smashed obtain protein and fat and lotion;
Juice is added into protein lotion with the ratio of volume ratio 0.1-0.3:1 in 5th step.
Transglutaminase, the albumen of low temperature edible bean cake are added in 6th step, the protein lotion of Xiang Hanyou vegetable juice
Matter content be 48%-52%, by this calculate protein, per kilogram protein addition 0.20-0.25g transglutaminase, 20-40 DEG C
Stand, after heat preservation 0.5-1 hours, 80-85 DEG C of heat treatment 3-5 minutes to get.
Protein dispersion heat treatment, can effectively change the structure of protein, to improve the dissolution of protein
Property, there is facilitation to the formation of subsequent emulsifying homogeneous and gel.
The beneficial effects of the present invention are: the present invention is using low temperature edible bean cake as raw material, after it is dispersed in suitable water,
By homogenization after mixing with vegetable oil, after obtaining the protein emulsion with embedding pigment isoreactivity substance, juice is added,
Adding transglutaminase again makes its solidification, does not need " to squeeze " process, straight forming is up to fruit vegetable bean curd;Not only make product more
Add it is health delicious, be more in line with modern pursue health and the diversified theory of food;The technique is equal by low temperature edible bean cake
Matter lotion, add juice after, using enzyme process straight forming, character relative to existing bean curd juice without it is free, in beautiful color,
Quality is close, full of nutrition, and for opposite traditional handicraft, bean curd fabrication cycle is short, saves water.
