Problems solved by technology

Patent CN1762227A discloses the method of feeding special feed and nutritional regulation to increase the CLA content in milk, but has the following disadvantages: 1. The production cost is high; 2. The CLA content is low, and the content ranges from 40 to 100 ml of CLA per 100 ml of milk. 90mg (0.04%~0.09%); 3. The CLA content fluctuates in a large range and is not easy to control; 4. The conjugated linoleic acid in this product is cis-9, trans-11-octadecadienoic acid isomers Dominant, accounting for about 90% of the total amount of CLA, while the content of trans-10, cis-12-octadecadienoic acid isomers is very small, and the singleness of isomer components results in the production of CLA by this method The efficacy of milk is incomplete, lacking the effects of trans-10, cis-12-octadecadienoic acid isomers in regulating fat metabolism and reducing body fat deposition
If microencapsulated CLA is added to milk, the wall material and emulsifier will enter the milk, which may affect the food safety of the product
The preparation process of microencapsulation is complicated, the cost is high, and additional equipment needs to be added

Embodiment 1

[0031] Weighing: whole fresh milk 10L, CLA-801g.

[0032] The fresh milk is harvested according to GB6914-86 ("Standards for Purchasing Raw Milk"), and the nutritional components are standardized according to GB5408.1-1999 ("Pasteurized Milk") and GB5408.2-1999 ("Sterilized Milk"). Every 100ml of fresh milk contains 28mg of CLA. CLA-80 is provided by Zhongshan Eureka Natural Medicine Co., Ltd., and is implemented in accordance with its enterprise product standards.

[0033] Heat the milk to 35°C-40°C, add the weighed CLA into the whole fresh milk under airtight conditions, stir, and homogenize once under the pressure of 45-50Mpa. After pasteurization, cooling and filling.

[0034] Determination of CLA content in the product: Take 11ml of milk, extract the milk fat according to the Gabriel method, accurately weigh 0.1g of fat, put it in a stoppered test tube, add reagents for methyl esterification. Take 1ml of n-hexane extract, add 5μl of 5mg / ml methyl heptadecanoate n-hexan...

Embodiment 2

[0036] Weighing: 10L whole milk, 100g conjugated linoleic acid glyceride.

[0037] Conjugated linoleic acid glycerides are provided by Zhongshan Eureka Natural Medicine Co., Ltd., in accordance with its enterprise product standards, with a content of ≥70%.

[0038] Heat the milk to 85-90°C, add the weighed conjugated linoleic acid glyceride into the whole fresh milk, stir, and homogenize once under the pressure of 10-15Mpa. After pasteurization, cooling and filling.

[0039] As determined by the above method, the total content of conjugated linoleic acid per 100ml of milk is 696mg.

Embodiment 3

[0041] Weighing: whole fresh milk 1L, CLA-80 500g.

[0042] Heat the milk to 70-75°C, add the weighed CLA into the whole fresh milk, stir, and homogenize under high shear for 5 minutes under the condition of 6000r / min. After pasteurization, cooling and filling.

[0043] As determined by the above method, the total content of each isomer of conjugated linoleic acid per 100ml of milk is 3.95g.

Abstract

A nutrients-intensified health-care milk containing multiple kinds of conjugated lenoleic acid isomer is prepared from the fresh milk through heating to 35-90 deg.C, directly adding conjugated lenoleic acid or its derivatives, and homogenizing by high pressure, or high-speed shearing, or ultrasonic waves.

Description

technical field [0001] The invention relates to a dairy product, in particular to fresh milk containing additives. Background technique [0002] Conjugated Linoleic Acid (CLA) is a natural unsaturated fatty acid found in milk fat and meat products of ruminants such as cattle and sheep, and is the most important energy factor and functional compound of milk. It has the effect of improving immunity, promoting and preventing diseases in children. [0003] Natural fresh milk should be rich in CLA, but the content of CLA has a great correlation with the season and feed composition, and the content is not stable. The content of CLA in the milk produced by the dairy cows that are naturally pastured to eat grass is relatively high, which can reach 80-100 mg per 100 ml of milk. However, the content of CLA in the milk of dairy cows fed with processed feed is greatly reduced, and the CLA content in every 100ml of milk is 20-40mg, which is only 1 / 5-1 / 3 of that ...
