Problems solved by technology

[0002] Conventional bovine colostrum powder production process adopts low-temperature freeze-drying or high-temperature powder spraying. Excessively high sterilization temperature or long time often lead to the inactivation of immunoglobulins, which makes the content of immunoglobulins in the final produced bovine colostrum powder unbalanced. low nutritional value

Abstract

The invention discloses organic bovine colostrum powder and a preparation method of the organic bovine colostrum powder. According to the preparation method, procedures of low-temperature freezing and drying and high-temperature powder ejection in the ordinary bovine colostrum powder production process are avoided; and in the bovine colostrum powder preparation procedures, ultrafiltration concentration dehydration and gamma-ray radiation sterilization are adopted. By utilizing the production process, both the purpose of dehydration concentration is achieved and the activation of immune globulin is not reduced; and meanwhile the gamma-ray radiation sterilization ensures complete nutrition components and ensures the thoroughness in sterilization. Clinical tests show that when compared with bovine colostrum powder prepared by using the conventional high-temperature powder ejection method, the bovine colostrum powder disclosed by the invention is high in IgG content and excellent in physicochemical indexes of protein, fat, moisture, acidity and various microbiological indicators.

Description

technical field [0001] The invention belongs to the technical field of preparation of health care products, and in particular relates to an organic bovine colostrum powder and a preparation process thereof. Background technique [0002] Conventional bovine colostrum powder production process adopts low-temperature freeze-drying or high-temperature powder spraying. Excessively high sterilization temperature or long time often lead to the inactivation of immunoglobulins, which makes the content of immunoglobulins in the final produced bovine colostrum powder unbalanced. Low, nutritional value is not high. Contents of the invention [0003] The object of the present invention is to provide a kind of organic bovine colostrum powder; Another object of the present invention is to provide the preparation process of this kind of organic bovine colostrum powder. [0004] The object of the invention is achieved through the following technical solutions: [0005] An organic bovine ...
