Description
Technical field
The present invention relates to dairy fermentation technical field, and in particular to a kind of acidified milk and preparation method thereof, is more particularly to
A kind of acidified milk containing omega-3 polyunsaturated fatty acids and preparation method thereof.
Background technology
Understanding with consumer to probiotics health concept, the product development of dairy producers is more with rich in featured function
Probiotics fermention breast be attraction, such as BB12, LGG.Research is found by inquiry, and China belongs to omega-3 polyunsaturated fatty acids
One of country of wretched insufficiency is taken in, its effectively supplement is to improve one of important channel of national health.ω -3 how unsaturated fat
Fat acid is the necessary aliphatic acid that human body itself can not be synthesized, and can only be fed by food, mainly including alpha-linolenic acid, 20
Carbon 5 alkene acid and docosahexaenoic acid etc..It is to constitute the important substance of cell membrane, form relevant, tune with cranial nerve and retina
Save the critical functions such as blood fat.The omega-3 polyunsaturated fatty acids of daily consumption derives from deep sea fish oil, marine alga, microalgae and flax
Seed, perilla seed etc..The omega-3 polyunsaturated fatty acids in deep sea fish oil source has dense fishlike smell, and oxidizable.And flax
Other dispensings rich in omega-3 polyunsaturated fatty acids such as seed are in recent years due to the significant beneficial function gradually fashionable whole world.In addition
Most people can not eat deep-sea fish everyday in daily life, also without specially supplement intake containing omega-3 polyunsaturated fatty acids
Special diet food or health food so that the omega-3 polyunsaturated fatty acids of daily intake is differed very with the demand of human normal
Far.
Fermented dairy product of the in the market rich in omega-3 polyunsaturated fatty acids is less, and dairy products supplement albumen as people
The important sources of the nutritional ingredient such as matter and calcium, by omega-3 polyunsaturated fatty acids added to wherein, can meet domestic consumer couple
The supplement of polyunsaturated fatty acid intake, with wide market prospects.
The content of the invention
To solve defect in the prior art, the present invention provides a kind of acidified milk, by the way that omega-3 polyunsaturated fatty acids is added
It is added in acidified milk, meets supplement of the domestic consumer to polyunsaturated fatty acid intake.

(2) leavening is seeded in the cow's milk after step (1) processing and carries out fermentation process；
(3) omega-3 polyunsaturated fatty acids is after aseptic process, added in the cow's milk after step (2) fermentation process,
After stirring, sterile filling refrigeration.
Heretofore described raw milk is the conventional raw milk in this area.Described white sand sugar and starch is that this area is normal
Advise material.
Wherein, temperature when step (1) described raw milk, the mixing of white sand sugar and starch is preferably maintained at 45-55 DEG C；With/
Or mixing time is 5-15min；And/or thermally-sterilized condition is：85 DEG C of temperature, time 15-20min.
More preferably, the temperature when raw milk, the mixing of white sand sugar and starch is 50-55 DEG C；And/or mixing time is
10-15min。
Wherein, above-mentioned thermally-sterilized condition can also be replaced with following condition：90-95 DEG C of temperature, time 5-10min.
Step (2) fermentation process condition is preferably：Fermentation time is 4-7h, and fermentation temperature is 35-45 DEG C.More preferably, institute
The fermentation process time is stated for 5-6h, fermentation temperature is 40-45 DEG C.
Omega-3 polyunsaturated fatty acids aseptic process described in step (3), processing mode can be heat treatment, membrane filtration and
Any of ultraviolet irradiation.
The omega-3 polyunsaturated fatty acids that the present invention is used is field of food conventional substances, can be simple ω -3 many not
Flax seed product based on saturated fatty acid or omega-3 polyunsaturated fatty acids.
On the basis of common sense in the field is met, above-mentioned each optimum condition can be combined, and produce each good reality of the present invention
Example.
Above-mentioned acidified milk can be prepared into various fermented dairy products, every acidified milk using the present invention according to actual conditions
The dairy products of preparation, are within the scope of the present invention.
