Preparation method of 100% liquid pure goat milk preservable at normal temperature for long term

Abstract

The invention relates to the technical field of drinks, and concretely relates to a preparation method of 100% liquid pure goat milk preservable at normal temperature for a long term. The method comprises the following steps: 1, taking 100% raw goat milk; 2, examining, and carrying out cold chain; 3, filtering and centrifuging to purify the goat milk; 4, pasteurizing and homogenizing; 5, instantly disinfecting at a super-high temperature; 6, homogenizing again; 7, removing the mutton smell of the goat milk, and disinfecting at a super-high temperature; and 8, carrying out aseptic packaging. The inherent mutton smell and characteristics of the goat milk are removed through processing the raw goat milk, so problems comprising large difficulty in present technologies for processing the goat milk to normal temperature liquid goat milk, and long-term storage of the liquid pure goat milk at normal temperature are solved.

Description

1. Technical field: [0001] The invention relates to the technical field of dairy products, in particular to a preparation method of 100% liquid pure goat milk that can be stored for a long time at normal temperature. 2. Technical background: [0002] The difference between goat milk and cow's milk or human milk lies in its higher digestibility, unique alkalinity, high buffering capacity and certain therapeutic value in human medicine and nutrition. People's love for goat milk products is due to the recent Healthy food requirements and consumption trends in some developed countries, and alternatives for consumers who are allergic or intolerant to milk, but due to the inherent smell and characteristics of goat milk, goat milk is processed into room temperature liquid milk The technical difficulty is high, which limits the development of goat milk to a large extent. At present, the production technology of goat milk products in my country is backward, and the liquid pure goat mil...

[0002] The difference between goat milk and cow's milk or human milk lies in its higher digestibility, unique alkalinity, high buffering capacity and certain therapeutic value in human medicine and nutrition. People's love for goat milk products is due to the recent Healthy food requirements and consumption trends in some developed countries, and alternatives for consumers who are allergic or intolerant to milk, but due to the inherent smell and characteristics of goat milk, goat milk is processed into room temperature liquid milk The technical difficulty is great, which limits the development of goat milk to a large extent. At present, the production technology of goat milk products in my country is backward, and the liquid pure goat milk products that cannot be stored at room temperature for a long time are problematic.

[0003] The thermal stability of goat milk is lower than that of milk, and protein clots will appear during ultra-high temperature sterilization or sterilization and concentration. The light ones are flocculent and floating, and the severe ones will have clots that precipitate and attach to the sterilizer or concentrator. Heating on the wall, affecting product quality
