Embodiment 1

[0057] Such as figure 1 As shown, this embodiment provides a middle-aged and aged yak milk powder, and the raw materials for preparing the yak milk powder include: raw yak milk, phospholipids, plant stanol esters and animal Bifidobacterium NMC.

[0058] The preparation method of the middle-aged and aged yak milk powder comprises the following steps:

[0059] Step 1, degreasing and standardization: 6690 kg of raw yak milk with a milk fat content of 5.79% and a milk solid content of 17% is used. After calculating according to the following formula according to the amount of raw yak milk, 3063 kg of raw yak milk is fully defatted. Then it was added to the remaining 3627kg of raw yak milk and mixed evenly to obtain standardized raw yak milk, and the extracted yak milk fat was refrigerated for later use;

[0060]

[0061] Step 2, homogenization: use a homogenizer to homogenize the standardized raw yak milk obtained in step 1 in strict accordance with the "Operating Procedures f...

Embodiment 2

[0074] This example is an optimization scheme based on Example 1, and also provides a middle-aged and aged yak milk powder. The raw materials for preparing the yak milk powder include: raw yak milk, phospholipids, plant stanol esters and animal bifido Bacteria NMC.

[0075] The specific preparation method is as follows:

[0076] Step 1, degreasing and standardization: use 6889kg of raw yak milk with a milk fat content of 5.37% and a milk solid content of 16.4%. 3727kg of raw yak milk is mixed evenly, and the fat of the yak milk is refrigerated for later use;

[0077] Step 2~step 10 are identical with embodiment 1.

[0078] Step 11, cooling: set the temperature of the first stage of the fluidized bed to 67°C, the temperature of the second stage to 57°C, and the temperature of the third stage to 24°C, place the powder obtained in step 9 in the fluidized bed for air cooling, and reduce the temperature of the powder to below 30°C to obtain Semi-finished milk powder 999kg;

Embodiment 3

[0083] Such as figure 2 As shown, this embodiment is an optimization scheme based on Example 1, and also provides a middle-aged and elderly yak milk powder. The preparation method of the yak milk powder is as follows:

[0084] Step 1, mixing ingredients: use 6889kg of raw yak milk with a milk fat content of 5.37% and a milk solid content of 16.4%. After calculating according to the amount of raw yak milk, 3162kg of raw yak milk is fully skimmed, and then added to the remaining 3727kg Mix raw yak milk evenly to form standardized yak milk, and refrigerate the extracted yak milk fat for later use; mix 180kg of desalted whey powder, 120kg of concentrated whey protein powder, 80kg of inulin, 110kg of maltodextrin, and 100kg of edible vegetable oil with purified water Dissolve to make solution B; add 3kg of mineral premix into purified water to dissolve it completely to make solvent B; add solution A and B to standardized yak milk, mix evenly and stir for 1 hour, then cool and temp...

Abstract

The invention provides yak milk powder for middle-aged and elderly people and a preparation method thereof. The yak milk powder for the middle-aged and elderly people is prepared from raw yak milk, phospholipid and plant stanol ester. The preparation method includes the steps that during preparation, part of fresh milk is completely degreased and then mixed with whole raw yak milk, and the partially degreased yak milk powder is prepared; and part of yak milk fat obtained through degreasing is used for dissolving the phospholipid and the plant stanol ester, spraying of the phospholipid and theplant stanol ester is achieved in the mode that nitrogen is sprayed through a double-airflow nozzle, and the problem that due to addition of the plant stanol ester, the resolubility of the milk powderis poor is solved. The yak milk powder for the middle-aged and elderly people is rich in plant stanol ester, beneficial to blood fat health of people with dyslipidemia, high in content of calcium andconjugated linoleic acid, low in content of trans-fatty acid, balanced in nutrition, easier to digest and absorb, and suitable for the middle-aged and elderly people to eat.

Description

technical field [0001] The invention belongs to the technical field of dairy product processing, and in particular relates to a middle-aged and aged yak milk powder and a preparation method thereof. Background technique [0002] Yaks live on the Qinghai-Tibet Plateau with high altitude, low air pressure, low temperature, and strong ultraviolet rays. They live by aquatic plants and are in a semi-wild and semi-grazing state. The harsh living environment makes yaks resistant to hypoxia, cold and have super immunity. The content of milk protein, milk fat and dry matter in yak milk is extremely high; its content of iron, zinc, calcium, essential amino acids, vitamin A, CLA, etc. is also higher than that of ordinary milk. Known as "Super Food". Yak milk contains 18 kinds of amino acids, including a complete range of essential amino acids, and the content is higher than that of ordinary cow's milk and goat's milk. Yak milk has high nutritional value and special functions. Its na...
