Problems solved by technology

Chinese patent publication CN104663884A discloses a pasteurized milk containing probiotics and a preparation method thereof. By using Lactobacillus casei Zhang as a probiotic in dairy products, although it has good survival rate and stability, the nutritional value remains to be seen. increase, and the shelf life of the product is still short (within 7 days)
[0004] Since cow's milk is a good medium for probiotics, when probiotics are added to pasteurized milk, the phenomenon of proliferation and fermentation will usually occur, which will increase the acidity of the product and cause curdling, which will greatly affect the overall sensory Therefore, there is no pasteurized milk with probiotics added in the market at present, and there is no combination technology of probiotics suitable for pasteurized milk

Embodiment 1

[0073] A pasteurized milk that contains probiotics. Its probiotics are realized by adding a composition containing three different probiotics including Lactobacillus acidophilus, Bifidobacterium lactis, and Lactobacillus paracasei. The ratio of live bacteria among the three lactobacilli is: 5%: 80%: 15%, and the total amount added is 0.2*10 8 CFU / mL.

[0074] The preparation method of the pasteurized milk comprises the following process links:

[0075] S1. Milk collection and pretreatment: Select raw milk that has been cooled to 2-6°C immediately after milking in the pasture, and is guaranteed to be delivered to the factory within 24 hours for milk collection. During the milk collection process, 100-mesh filter bags are used to filter the raw milk and The temperature of the raw milk was reduced to 2 °C again. During this process, the sensory, total number of colonies and somatic cells of the raw milk are tested at the same time to ensure that the raw milk entering the next ...

Embodiment 2

[0086] A pasteurized milk that contains probiotics. Its probiotics are realized by adding a composition containing three different probiotics including Lactobacillus acidophilus, Bifidobacterium lactis, and Lactobacillus paracasei. The ratio of live bacteria among the three Lactobacillus is: 6%: 85%: 9%, and the total amount added is 0.3*10 8 CFU / mL.

[0087] The preparation method of the pasteurized milk comprises the following process links:

[0088] S1. Milk collection and pretreatment: Select raw milk that has been cooled to 2-6°C immediately after milking in the pasture, and ensure that it will be delivered to the factory within 24 hours for milk collection. During the milk collection process, 120 mesh filter bags are used to filter the raw milk and The temperature of the raw milk was lowered to 4°C again. During this process, the sensory, total number of colonies and somatic cells of the raw milk are tested at the same time to ensure that the raw milk entering the nex...

Embodiment 3

[0099] A pasteurized milk that contains probiotics. Its probiotics are realized by adding a composition containing three different probiotics including Lactobacillus acidophilus, Bifidobacterium lactis, and Lactobacillus paracasei. The ratio of live bacteria among the three lactobacilli is: 8%: 85%: 7%, and the total amount added is 0.5*10 8 CFU / mL.

[0100] The preparation method of the pasteurized milk comprises the following process links:

[0101] S1. Milk collection and pretreatment: Select raw milk that has been cooled to 2-6°C immediately after milking in the pasture, and is guaranteed to be delivered to the factory within 24 hours for milk collection. During the milk collection process, 150-mesh filter bags are used to filter the raw milk and The temperature of the raw milk was lowered to 5°C again. During this process, the sensory, total number of colonies and somatic cells of the raw milk are tested at the same time to ensure that the raw milk entering the next pr...

Abstract

The invention belongs to the technical field of dairy product processing, and particularly discloses pasteurized milk containing probiotics and a preparation method of the pasteurized milk. The pasteurized milk containing the probiotics contains a probiotic composition which is prepared by combining lactobacillus acidophilus, bifidobacterium lactis and lactobacillus paracasei. According to the pasteurized milk containing the probiotics, the shelf life of a final product is prolonged to 20 days through concentration of the fresh milk, optimization of a pasteurization process and optimal proportioning and addition of the probiotics, the nutritional value of the product is improved, high active substance content, low furosine content,high viable count of probiotics and sensory stability of the product within the shelf life can be ensured; and meanwhile, conservation energy consumption and material loss are designed in production, so that the production cost is reduced. The method is suitable for large-scale industrial production and has a great application prospect.

Description

technical field [0001] The invention relates to the technical field of dairy product processing, in particular to pasteurized milk containing probiotics and a preparation method thereof. Background technique [0002] Probiotics refer to living microorganisms that, when reaching a certain amount, have a healthy effect on the host. Probiotics are a type of active microorganisms that are beneficial to the host by colonizing in the human body and changing the composition of the flora in a certain part of the host. By regulating the immune function of the host mucosa and system or by regulating the balance of intestinal flora, it can promote nutrient absorption and maintain intestinal health, so as to produce a single microorganism or a combination of mixed microorganisms with a clear composition that is beneficial to health. In order to exert the probiotic effect of probiotics, it is necessary to ensure that a sufficient amount of active bacteria is consumed every day, and the ...
