Description

A kind of yoghourt stabilizer
Technical field:
The invention belongs to food processing technology field, relate to a kind of stabilizing agent, particularly a kind of yoghourt stabilizer that adds when preparing yoghourt with long shelf life.
Background technology:
Sour milk is a kind of wide fermented dairy product popular to people, the nutritive value of sour milk is very high, not only have the nutritious characteristics of milk, also have the effect that promotes to digest and assimilate with special health care concurrently, milk is behind lactobacillus-fermented, part protein resolves into micromolecular peptide and amino acid etc., easier digestion; Butter oil also is decomposed under fermentation, and the aliphatic acid of formation has increased by 2~6 times than raw material milk; The lactic acid that lactose produces by fermentation can not only make the alkalescent material in the enteron aisle be transformed into faintly acid, suppress the breeding of enteron aisle spoilage organisms, prevent the protein fermentation, be conducive to stomach digestion, can also reduce gastric acid secretion, improve the utilization rate of mineral elements such as calcium, phosphorus and iron.Existing common sour milk needs 4 ℃-6 ℃ refrigerations down, shelf-life was generally about 20 days, common sour milk acidity in storage can improve constantly and make sour milk become sourer, higher or time of temperature is long then can be made sour milk growth harmful bacteria, yeast or bacillus etc. and goes bad, and occurs problem such as whey is separated out, edible glue is broken, coarse mouthfeel easily and influences mouthfeel and the local flavor of sour milk.Compare with common sour milk, yoghourt with long shelf life carries out sterilization processing after fermentation ends, and the microorganism that pollutes in the production process, especially fungi such as mould and yeast are just in time killed before a large amount of propagation, has eliminated rotten hidden danger; Heat treatment also makes part lactic acid bacteria and the enzyme deactivation in the sour milk, controls the generation of acidifying problem behind the product effectively.At present, the successful Application of good sanitary condition and production equipment and stabilizing agent protection system makes yoghourt with long shelf life reach the above shelf-life of half a year.
At present, producing yoghourt with long shelf life production technology commonly used has two kinds, and a kind of is to adopt pasteurize, sterile filling technology; Another kind is the technology of two-stage sterilization after the employing can, but when adopting these two kinds of production technologies to produce yoghourt with long shelf life, all need reasonably to select and use yoghourt stabilizer, otherwise cause easily in sterilization process that the aggegation of protein in the sour milk, whey are separated out, viscosity obviously reduces and problem such as loss of flavor.At the problems referred to above, in general in pasteurization yoghourt, can add various stabilizing agents according to form, mouthfeel and the stability of sour milk, these stabilizing agents generally comprise the characteristics that have when stabilizing agents such as agar, converted starch, sodium carboxymethylcellulose, pectin, gelatin and xanthans use separately in sour milk, converted starch, sodium carboxymethylcellulose, pectin and xanthans belong to the tackifying stabilizing agent, and agar and gelatin belong to the gelation stabilizing agent.If only use the tackifying stabilizing agent can make sour milk have sticky mouthfeel, swallowing property is relatively poor, and obviously covers the local flavor of sour milk; Though gelatin also has gelation, but still have sticky mouthfeel, and the gel that gelatin forms melts about 25 ℃, understand the thawing of the system of Himdu logic glue when sour milk is placed and desaturation under normal temperature.Agar has extraordinary gelation, agar solution begins to solidify in about 40 ℃, and the gel that agar forms needs could melt more than 85 ℃, still viscosity and gel force preferably be can keep when therefore the sour milk of making as stabilizing agent of agar is placed under normal temperature, and good the swallowing property of sour milk and local flavor release given.Therefore, in yoghourt with long shelf life, also use tackifying and gelation stabilizing agent, namely use agar and converted starch, sodium carboxymethylcellulose etc. as yoghourt stabilizer, and the process conditions of no-float, can produce the yoghourt with long shelf life that almost has identical local flavor and mouthfeel with common sour milk.
In order to prolong the shelf-life of sour milk, generally can adopt high temperature sterilization or high temperature for a long time according to the difference of the yoghourt stabilizer that adds in the prior art, need add more sodium carboxymethylcellulose (CMC-Na) or pectin stabilization protein when adopting the manufacture method of the long-time sterilization of high temperature, prevent that protein aggegation and whey in the sterilization process from separating out, for example Chinese patent CN101889611A discloses a kind of preparation method and special yoghourt stabilizer thereof of yoghourt with long shelf life, and date of publication is on November 24th, 2010; Chinese patent CN102232418A discloses manufacture method and the yoghourt stabilizer of yoghourt with long shelf life, and date of publication is on November 9th, 2011; All used sodium carboxymethylcellulose (CMC-Na) as yoghourt stabilizer in these two kinds of methods, sour milk is stable fine protein after the long-time sterilization of high temperature, whey can not occur and separate out phenomenon, but with the yoghourt with long shelf life of this method and stabilizing agent manufacturing have clearly sticky sense and relatively poor swallowing property, and sour milk has almost lost gelation after sterilization, with compare mouthfeel without the common sour milk of sterilization notable difference arranged, or present the low mouthfeel similar to beverage of viscosity; Can not need add sodium carboxymethylcellulose (CMC-Na) or pectin when adopting the manufacture method of high temperature as yoghourt stabilizer, for example Chinese patent CN101849577A discloses a kind of long-shelf-life pasteurization yoghourt and preparation method thereof, date of publication is on October 6th, 2010, use starch in this method, agar, the gelatin isocolloid is as yoghourt stabilizer, sour milk after the fermentation is used 65-80 ℃, the condition of 15-60 second is carried out sterilization, although adopt the sour milk of this method preparation to improve viscosity and the gelation of product, and prolonged the sour milk shelf-life at normal temperatures, but gained sour milk products matter structure is thick and caking is arranged and fine and smooth inadequately, and the puckery sense of obvious powder is arranged.
Summary of the invention:
The objective of the invention is to overcome the shortcoming that prior art exists, seek design a kind of yoghourt stabilizer is provided, utilize yoghourt stabilizer to realize stability, improve the shelf-life, make product have good mouthfeel and local flavor; Yoghourt stabilizer effective stable protein in the sterilization process of sour milk prevents that whey from separating out, and has hear resistance, acid resistance and the anti-shearing of height, especially can make sour milk after the pasteurize have the quality of stiff, swallow sense well, do not have sticky sense, delicate mouthfeel is smooth.
