Embodiment 1

[0046] In this example, pure milk was prepared as follows:

[0047] 1. PET bottle injection molding

[0048] The content of the oxygen absorbing agent was 3% by mass, and the content of the barrier agent was 15% by mass.

[0049] 2. The raw milk is sterilized by steam injection ultra-high temperature sterilization method, the temperature is 143°C, and the time is 3 seconds.

[0050] 3. The sterilized product is flash-cooled to 81°C, and degassed instantaneously at the same time. The vacuum degassing pressure is 0.05bar.

[0051] 4. Pour the base material obtained in the previous step into the PET bottle in step 1. The volume of the base material accounts for 80% of the total volume of the bottle, and then quickly add 0.15 grams of liquid nitrogen dropwise to the space above the base material in the bottle, and cover the bottle cap .

Embodiment 2

[0053] Pure milk was prepared according to the method of Example 1, except that the content of the oxygen absorbing agent was 2.5% by mass, and the content of the barrier agent was 18% by mass.

Embodiment 3

[0055] Pure milk was prepared according to the method of Example 1, except that in step 2, the sterilization temperature was 154° C. for 0.25 s.

Abstract

Pure milk and a preparing method thereof are provided. The pure milk includes a transparent container and a pure milk base material disposed in the container. The pure milk is beautiful and high in stability. In particular, the container has good light barrier performance and oxygen isolation performance, and the pure milk is not liable to decay in long-term storage and has a long shelf life.

Description

technical field [0001] The invention relates to the field of food. In particular, the present invention relates to pure milk and its preparation method. Background technique [0002] Pure milk refers to dairy products that only contain raw milk. Since it does not contain other additives, it is prone to spoilage and deterioration, so it has strict requirements on the production process. [0003] PET (polyethylene terephthalate) bottle has the characteristics of "large capacity, transparent, intuitive, light and easy to open, refrigerated, easy to carry, sturdy, and recyclable", which provides a broad opportunity for its development. market expectation. Judging from the market share of major beverage countries in the world, PET bottles account for more than 70% of the four major beverage packages of carbonated drinks, fruit juice drinks, tea drinks, and bottled water, but they are less used in dairy products. At present, ordinary PET bottle packaging is only used in a small...
