Description

A kind of single cream cheese and preparation method thereof
Technical field
The present invention relates to a kind of single cream cheese and preparation method thereof.
Background technology
Current single cream cheese mainly adds rare cream in milk, makes it fat standardising to 4%~9%, then, by inoculation fermentation, interpolation renin, after working up curd, with cloth bag or membrane filtration, carrys out discharging whey.In this process, because grumeleuse grain usually can stop up the hole of cloth bag or film, affect the velocity of discharge and the final moisture of product of whey.The product obtaining is also easily because discharging whey overlong time produces rear acid, and the matter structure of finished product is even not, and easily bleed, is vulnerable to the pollution of microorganism.
Summary of the invention
The technical problem to be solved in the present invention is to overcome single cream cheese of the prior art easily because discharging whey overlong time produces rear acid, and the matter structure of finished product is even not, easily bleed, is vulnerable to the defect of the pollution of microorganism, and a kind of single cream cheese and preparation method thereof is provided.Preparation method's discharging whey of the present invention is quick, is difficult for causing filtering material to stop up, and reduces and cleans the frequency; Its local flavor of single cream cheese, matter structure and smear that the present invention simultaneously makes are all better than common single cream cheese, avoid microbial contamination.
Inventor finds under study for action, and the hole that stops up cloth bag or film is mainly the butter oil ball that particle size is larger, and inventor tries butter oil first from milk, to separate, and after working up curd discharging whey, then returns the preparation method who adds rare cream and makes single cream cheese.But the single cream cheese making according to the method, due to rare cream not by fermentation, the single cream cheese that the local flavor of product makes not as common process is strong, simultaneously, return and to add the process need that rare cream mixes and carry out mechanical agitation and heat treatment to a certain degree, easily cause the sex change of local acidic protein heat, the configuration state of destruction product, occur powder sense, experiment ends in failure.Finally by following technical proposals, solve the problems of the technologies described above.
