Description

A kind of dairy produce and its production technology
Technical field
The present invention relates to a kind of dairy produces and its production technology with Vacuum Freezing & Drying Technology production, belong to food industry neck Domain.
Background technique
Yoghourt not only remains all nutriments of milk, and by the process of fermentation, can by milk sugar and Breaks down proteins are easy at small-molecule substance by human consumption and absorption.In addition, the probiotics contained in Yoghourt is beneficial to human body Intestinal health weakens spoilage organisms and generates toxin in human body, and can inhibit the generation of certain carcinogens, has certain anti-cancer Effect, so more and more popular with consumers.However sour milk product is mostly in the majority with coagulating type currently on the market, it need to be 2~3 DEG C environment in refrigerated, the shelf-life is generally 21 days, and kind taste nutrition is more single, and the shelf-life is shorter, store method It is special, it is inconvenient to carry, it is unable to satisfy safe and healthy modern metropolitan cities crowd, full of nutrition, multiple tastes, conveniently consumes Demand.
In view of the above technical problems, Patent No. 2013105965374 " a kind of vacuum freeze drying fruit vegetable powder Yoghourt and Preparation method " (calling patent 1 in the following text), Patent No. 201610265329X " a kind of vacuum freeze drying fruit vegetable powder Yoghourt and its The innovation and creation of preparation method " (calling patent 2 in the following text) respectively provide a set of technical solution, but two sets of technical solutions still remain Certain defect.For example, the butter needs in patent 1 are sufficiently melted to fluid in the environment of 50 DEG C, need to heat pansman Skill, temperature is easy solidification after reducing, so that finished product mouthfeel is partially hard;The temperature of sizing is -30 DEG C, and the time needs 2~3h, when quick-frozen Between need 4~6h, add up to need 6~9 hours, time-consuming;In addition, molten beans freeze temperature is excessively high, the probiotics in Yoghourt is basic It is dead.For another example in patent 2, cream needs -15 DEG C of deepfreezes, needs when use slow to freeze or be warming up to stream shape body;Yoghourt and Sour milk powder needs to add emulsifier and thickener is carried out being warming up to 50 DEG C and be dissolved, and boiling emulsion process, Yoghourt itself Probiotic active reduces, and may decay and accelerate to death;Need to use the addition such as emulsifier, thickener, citric acid, malic acid Agent;In the freezer of -8 to -12 degree, delay and freeze 2~3 hours, the quick-frozen time is 2~3 hours, the sizing speed for wanting 4-6 hours altogether Freeze the time, the time is long.
On the basis of the above, the invention patent has carried out upgrading to the production technology of such dairy produce, in certain journey Solves the defect of the prior art on degree.
Summary of the invention
The present invention is directed to overcome prior art defect, a kind of dairy produce and its production technology are provided.Specific technical solution is such as Under:
