Problems solved by technology

Unreasonable processing methods can easily lead to excessive nitrosamines in food and endanger human health
However, common lactic acid bacteria preparations are not resistant to acid and salt in gastric acid after being taken by the human body, and are easy to die, and there are many proteases in the stomach and intestinal tract, which are easy to decompose lactic acid bacteria, and finally the number of lactic acid bacteria in the intestinal tract is very small

preparation example Construction

[0029] The above-mentioned preparation method of the kimchi lactic acid bacteria capsule that can reduce nitrosamines in the human body comprises the following steps:

[0030] 2.1) Compounding Lactobacillus pentosus powder and Lactobacillus brevis powder in proportion, and preparing composite bacteria powder;

[0031] 2.2) Stir fructose syrup: soybean oil: compound bacteria powder in proportion to make a paste, and then put it in a boiling coating machine. Enteric-coated at 2-10g / min, dried for 2-10 minutes before taking out, and screened with 10-40 mesh to obtain kimchi lactic acid bacteria capsules that can reduce nitrosamines in the human body.

Embodiment 1

[0033] A pickle lactic acid bacteria capsule capable of reducing nitrosamines in the human body, comprising the following raw materials: composite bacteria powder, fructose syrup and soybean oil; wherein, in the composite bacteria powder, the mass ratio of Lactobacillus pentosus powder and Lactobacillus brevis powder It is 4:1. According to the mass ratio, high fructose syrup: soybean oil: composite bacteria powder = 1:1:5.

Embodiment 2

[0035] A pickle lactic acid bacteria capsule capable of reducing nitrosamines in the human body, comprising the following raw materials: composite bacteria powder, fructose syrup and soybean oil; wherein, in the composite bacteria powder, the mass ratio of Lactobacillus pentosus powder and Lactobacillus brevis powder It is 2:1. According to the mass ratio, high fructose syrup: soybean oil: composite bacteria powder = 1:1:5.

Abstract

The invention relates to the technical field of strain preparation, in particular to a leuconostoc kimchii capsule capable of reducing nitrosamine in human bodies and a preparation method of the leuconostoc kimchii capsule. The method includes steps: 1) degradation nitrosamine strain screening; 2) acid-resistant bile-salt-resistant strain screening; 3) subjecting lactobacillus pentosus and lactobacillus brevis excellent in nitrosamine degradation performance, acid resistance and bile salt resistance to freeze drying, and uniformly crushing; 4) compounding the obtained lactobacillus pentosus and lactobacillus brevis according to a ratio of 10:1-1:2; 5) proportionally stirring high fructose syrup, soybean oil and bacterial powder, well mixing into a paste state, adding mixed liquid into a boiling coating machine, performing coating of enteric coatings under conditions that the material temperature is 30-45 DEG C, the spray pressure is 0.1-0.50MPa and the flow rate is 2-10g / min, drying for 2-10min before taking out, and screening whole particles through a 10-40-mesh screen. The leuconostoc kimchii capsule obtained according to the method is capable of reducing nitrosamine in human bodies and high in entric solubility.

Description

technical field [0001] The invention relates to the technical field of strain preparation, in particular to a kimchi lactic acid bacteria capsule capable of reducing nitrosamines in a human body and a preparation method thereof. Background technique [0002] Nitrosamine is a kind of N-nitroso compound, which is usually formed by nitrosylation of nitrite, amine and other nitrogen-containing substances under suitable conditions. [0003] Common foods, cosmetics, beer, and cigarettes all contain nitrosamines. Smoked and cured foods contain a large amount of nitrosamines, which will remain in the body after eating, and a large amount will endanger human health. The incidence of certain digestive system tumors, such as esophageal cancer, is related to the amount of nitrosamines ingested in the diet. For example, in countries such as Iceland, Finland and Norway, where smoked fish is customary, the incidence of stomach cancer is very high. Residents of gastric cancer and esophag...
