Problems solved by technology

[0004]Since the 1990s, antihypertensive research on microorganisms, especially lactic acid bacteria, has been highly valued. It has been reported in relevant literature that lactic acid bacteria can reduce serum cholesterol levels and increase serum cholesterol levels. Medium SOD activity, lowering the level of lipid peroxide, has the function of assisting blood pressure lowering blood lipid and antioxidation, but the auxiliary blood pressure lowering blood lipid and antioxidation function of lactic acid bacteria has differences in strains and even strains, and it is applied to specific fermented milk Its efficacy in the product needs to be further verified

Embodiment 1

[0032] Embodiment 1: Determination of growth kinetics characteristics of Lactobacillus paracasei ET-22 fermented milk

[0033] 1. Experimental strains

[0034] Lactobacillus paracasei ET-22 (CGMCC No.15077) used in the technical solution of the present invention;

[0035] Control strain 1: commercial Lactobacillus paracasei strain L.CASEI 431;

[0036] Control strain 2: commercial Lactobacillus paracasei strain LPC-37.

[0037] 2. Activation of the strain and culture of seed solution

[0038] (1) Strain activation: Lactobacillus paracasei was activated with MRS medium, and the strains that had grown to the logarithmic phase were taken and stored in glycerol tubes for future use. Among them, MRS medium (g / L): peptone 10.0g; yeast extract 5.0g; glucose 20.0g; anhydrous sodium acetate 5.0g; dihydroammonium citrate 2.0g; 2.0g; magnesium sulfate heptahydrate 0.2g; manganese sulfate 0.05g; beef extract 10.0g; agar 15g-20g.

[0079] Example 2. Fermentation of Lactobacillus paracasei ET-22 to prepare a milk beverage with anti-oxidation, blood pressure regulation and sleep regulation potential

[0080] This example provides a milk beverage prepared by fermentation of Lactobacillus paracasei ET-22, which has the potential of anti-oxidation, regulating blood pressure and regulating sleep. The manufacturing steps of this drink are as follows:

[0081] (a) Lactobacillus paracasei ET-22 is inoculated in skim milk and fermented, and fermented milk is obtained after fermentation;

[0082] (b) Blending a sweetener and / or a sour agent to form a blended liquid, mixing the blended liquid with the fermented milk prepared in step (a), and homogenizing to prepare a fermented milk beverage.

[0083] Further, the fermentation temperature in the step (a) is 37°C, and the fermentation time is 96h-120h.

[0084] Further, in step (b), the mixing volume ratio of the fermented milk and the blending solution is 1:2-4.

Abstract

The invention provides lactobacillus paracasei ET-22 capable of resisting oxidation and regulating blood pressure and application of the lactobacillus paracasei ET-22. The invention firstly provides an application of lactobacillus paracasei ET-22 in preparation of a composition with the effects of resisting oxidation, regulating blood pressure and / or regulating sleep, wherein the preservation number of the lactobacillus paracasei is CGMCC No.15077. Research finds that a lactobacillus paracasei strain fermented emulsion has the application in the aspects of oxidation resistance, blood pressure regulation, sleep regulation and the like, and can be widely applied to the fields of foods, medicines, feeds, chemical engineering and the like.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a kind of Lactobacillus paracasei (Lactobacillus paracasei) ET-22 (preservation number CGMCC No. 15077) fermented to prepare a composition with antioxidant, blood pressure and / or sleep regulation effects related applications. Background technique [0002] Aging is the biggest killer of human organs, and free radicals produced by the body are the main culprits of organ aging. When the body's mechanism for regulating free radicals is lost or unbalanced, excessive free radicals will damage cell DNA, change the protein structure in cells, attack cell membranes, and eventually lead to the death of somatic cells. Skin aging is also caused by prolonged exposure to ultraviolet light (UV exposure) or heat source (heat exposure), which induces a sharp increase in the amount of active oxygen, leading to dull skin, skin cancer and other diseases. [0003] Hypertension, toget...
