Embodiment 1

[0034] A preparation method of bovine colostrum, comprising the following steps:

[0035] (1) Colostrum collection: Colostrum collected within 3 days after calving of cows. During the collection process, the colostrum is required to be clean, pollution-free and fresh. The specific performance is that the colostrum is light yellow in color and has a fishy smell. There must be no impurities. After collection, refrigerate within 24 hours;

[0036] (2) Degreasing: at 25°C, the centrifuge speed is 3500 rpm, and the centrifugation time is 5 minutes, and the bovine colostrum in step (1) is centrifugally degreased;

[0037] (3) Casein removal: adopt acid treatment plus centrifugation to carry out casein removal treatment on the bovine colostrum that has undergone centrifugal degreasing treatment in step (2), the specific steps are: first adjust step (2) with 1mol / L HCl The pH of the defatted bovine colostrum in the medium is 4.0, let it stand for half an hour, then adjust the pH to 6...

Abstract

The invention discloses a preparation method of a bovine colostrum element. The method comprises the steps as follows: the bovine colostrum element is prepared from bovine colostrum used as a raw material through steps of degreasing, casein removal, sterilization, ultrafiltration concentration, freeze drying, ultrafiltration concentration and packaging. Casein and lactose removal processes are included in during processing of the product, and the product is very safe and application to vast people. Besides, the product not only contains immune globulin but also contains lactoferrin and thus has a very good effect of improving the immune functions of infants under the synergistic effect of the two components. Specifically, lactoferrin has broad-spectrum antibacterial, anti-oxidation, anti-cancer and immune system regulation functions and has very good body strengthening and healthcare effects on young and old people and weak people.

Description

technical field [0001] The invention belongs to the field of preparation of dairy products, in particular to a method for preparing bovine colostrum. Background technique [0002] There are as many as several hundred dairy farms in my country, and a dairy farm ranges from dozens of cows to hundreds or even tens of thousands, and a cow produces 50 to 100 kilograms of colostrum. Because colostrum has a bloody smell, it is not easy to be taken orally. Fresh colostrum contains hormones and is not suitable for direct consumption. In addition, the special ingredients in colostrum are not easy to absorb after oral administration. Bovine colostrum has been used as feed for calves for many years. or be discarded. Although bovine colostrum has been used as a health food for nearly 20 years, farms generally sell bovine colostrum to factories, or keep it for calves, and there are not many discarded colostrum, but it can be said that the utilization rate still needs to be improved. Mod...
