Abstract

A kind of preparation method of novel freezing bean curd belongs to bean product process technology;The method is comprised the following steps:(1) bean curd (2) ultrasound frozening (3) are made and refrigerates maturation (4) defrosting dehydration (5) micro-wave vacuum (6) packaging;The problems such as technology of this method ensure that freezed bean curd in good taste, delicious flavour, easy storage, ratio defective product high, stay in grade, effectively solution dehydration desiccation, rehydration hardly possible, for the large-scale production of further freezed bean curd provides condition.

Description

A kind of preparation method of novel freezing bean curd
Technical field
The present invention relates to a kind of preparation method of bean product.Relate generally to a kind of preparation method of novel freezing bean curd.
Background technology
Freezed bean curd is formed by the freezing of new fresh bean curd, due in good taste, delicious flavour, the easily spy such as storage, instant Point, extremely people like.Freezed bean curd is produced using traditional process in the market, and product yield ratio is low, and And soup is easily dehydrated in space during culinary art, boiling, makes taste bad, the crudy of dish is directly affected. Its internal protein structure can form spongy loose structure in the manufacturing process of freezed bean curd, be rich in certain elasticity, for protecting Water holding point and product quality are most important.And moisture is difficult to retain during the process such as traditional freezing, dehydration, drying can make bean curd, Therefore, the problems such as made freezed bean curd has easy dehydration desiccation, rehydration hardly possible, storage time is long also to produce hair health Phenomenon, it is impossible to be reduced, and need swollen supple-settlement.The present invention utilizes ultrasound frozening technical tie-up microwave vacuum drying technology system Make freezed bean curd, the shortcomings of overcome low traditional freezed bean curd ratio defective product, unstable quality and complex process.Freezed in bean curd and given birth to Apply the outer field energy of ultrasonic wave during product, without adding any additive improving quality, it is not necessary to add puffing softener to enter The swollen supple-settlement of row meets the direction of modern food Green Development.Ultrasound frozening technology makes the moisture in bean curd in micro- space of system Interior formation ice crystal nucleation, accelerates freezing speed, reduces freeze-off time, keeps bean curd quality fine and smooth, prevents cavernous body from excessively being formed, On the premise of ensureing that bean curd spongeization ductile strength is moderate, the mouthfeel for maintaining bean curd good, stabilization freezed bean curd product property. Micro-wave vacuum is the best method for dehydrating freezed bean curd, it is ensured that product is pure white, smooth, trickle, does not result in The problems such as wet in being done outside product, with original fresh bean curd almost without what difference after rehydration.Production technology of the invention passes through Ultrasound frozening technical tie-up microwave vacuum drying technology not only ensure that product quality, accelerate production efficiency, and be into one The large-scale production for walking freezed bean curd provides condition, creates more preferable economic well-being of workers and staff.
The content of the invention
In order to ensure freezed bean curd in good taste, delicious flavour, easily storage, ratio defective product is high, stay in grade characteristic, effective solution The certainly difficult technical problem of dehydration desiccation, rehydration.The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, are proposed A kind of preparation method of novel freezing bean curd, freezing beans are realized by ultrasound frozening technical tie-up microwave vacuum drying technology The stabilization of rotten product quality, is sufficiently reserved the nutritional ingredient in bean curd, accelerates production efficiency.
The technical problems to be solved by the invention are achieved through the following technical solutions:
A kind of preparation method of novel freezing bean curd, the method includes the steps:(1) selection high quality soybean, selected, Washing, immersion, defibrination, filtering, mashing off, point brain, bag slurry, it is compressing, obtain bean curd;(2) bean curd is naturally cooled into room temperature Afterwards, be cut into thumbnail, thumbnail carried out into ultrasound frozening treatment at -30~-40 DEG C, described ultrasonic time for 150~ 200min;(3) ultrasound is carried out at -10~-7 DEG C, is refrigerated 1~3 day after ultrasound, is maintained the circulation of air, and obtains freezed bean curd block; (4) after freezed bean curd block is thawed with 1~2h of cold water flush, it is dehydrated, the aqueous of freezed bean curd block is made using double roller extruding Measure is 25~30%;(5) processed using micro-wave vacuum at 50~70 DEG C;(6) it is cold after inflated with nitrogen is by dehydration after processing Frozen bean curd block is inflated packaging, obtains finished product freezed bean curd.
The size of thumbnail described in step (2) is 6cm × 6cm × 6cm.
Brief description of the drawings
The process route chart of accompanying drawing invention.
Specific embodiment
The specific embodiment of the invention is described in detail below in conjunction with the accompanying drawings.
