Embodiment 1

[0021] The invention provides a static and dynamic high-pressure combined sterilization process for milk, the sterilization process comprising the following steps:

[0022] The milk is centrifugally purified or filtered with 200-400-mesh nylon cloth to remove mechanical impurities visible to the naked eye; the purified milk is homogenized at room temperature at 16MPa-22MPa normal pressure; the prepared homogenized milk is prepared at 300MPa- Sterilize under 600MPa static pressure for 5min-20min, then carry out high-pressure homogeneous sterilization under 150MPa-400MPa pressure; immediately cool down to below 10°C, fill in sterilized packaging containers and store in 2- Store in a refrigerator at 8°C.

[0023] The application of a static and dynamic high-pressure combined sterilization process for fresh milk provided by the invention.

[0024] Furthermore, the present application also provides a non-vegetable protein beverage prepared by a milk static-dynamic high-pressure co...

Embodiment 2

[0026] On the basis of Example 1, this embodiment provides a static and dynamic high-pressure joint sterilization process for milk, wherein the milk is centrifugally purified or filtered with 200-400-mesh nylon cloth to remove mechanical impurities visible to the naked eye; The milk is homogenized under 16MPa and normal pressure at room temperature; after being sterilized under the static pressure of 300MPa for 5 minutes, and then subjected to high-pressure homogenization and sterilization under the pressure of 150MPa; the temperature is immediately lowered to below 10°C, and filled in sterilized containers. Store in a cold storage at 2-8° C. in a packaging container to obtain sterilized milk.

Embodiment 3

[0028] On the basis of Example 1, this embodiment provides a static and dynamic high-pressure joint sterilization process for milk, wherein the milk is centrifugally purified or filtered with 200-400-mesh nylon cloth to remove mechanical impurities visible to the naked eye; The milk is homogenized under 18MPa and normal pressure at room temperature, sterilized under the static pressure of 400MPa for 10 minutes, and then subjected to high-pressure homogenization and sterilization under the pressure of 250MPa; Store in a cold storage at 2-8° C. in a packaging container to obtain sterilized milk.

Abstract

The invention discloses a milk static and dynamic high-pressure combined sterilization process, which is characterized in that fresh milk is pretreated to remove impurities, and then static high-pressure sterilization and dynamic high-pressure sterilization are combined for sterilization, so that sterilized milk prepared by the technical scheme provided by the invention is finally obtained, and the production energy consumption is greatly reduced. The detection stability of the sterilized milk obtained by the preparation method provided by the invention completely meets the requirements of commodities on the market, and the sensory and microbiological indicators are in better levels, so that the problems of pure pursuit of long shelf life, low quality and the like in the milk sterilization process in the prior art are solved. However, the problems of high energy consumption, great influence on the taste of milk and the like exist in the actual production process, and the method has huge potential value for enriching milk products and developing the milk industry.

Description

technical field [0001] The invention belongs to the technical field of food processing, relates to the technical field of fruit juice processing, in particular to a milk static-dynamic high-pressure combined sterilization process and its application. Background technique [0002] HPP (High hydrostatic pressure), also known as high static pressure technology, refers to the pressure treatment of 100MPa-1000MPa on the material in the soft container at room temperature or slightly higher than room temperature, using water or other liquids as the medium, to A non-thermal processing technology that achieves the purpose of killing microorganisms, inactivating endogenous enzymes, and improving food quality. Since HPP only acts on non-covalent bonds such as hydrogen bonds, ionic bonds, and hydrophobic bonds in food biomacromolecules, it has no significant effect on covalent bonds in small molecules such as vitamins, pigments, and volatile flavor substances. Therefore, The applicatio...
