Embodiment 1

[0035] (1) Preparation of seed solution

[0036] Insert the lactobacillus into the liquid MRS medium, the pH value is 6.2-6.6, and culture it in a static shaking flask at 37°C for 2 days to obtain the seed liquid;

[0037] (2) Fermentation culture

[0038]The seed liquid is inserted in the 5L fermentation tank according to the inoculation amount of 5wt%, and the fermentation medium formula is: Cordyceps militaris powder 8g / L, glucose 5g / L, fructose 18g / L, sodium acetate 5 g / L, magnesium sulfate 2g / L L, water balance, pH value is 6.2-6.6. After inoculation, aeration and agitation culture was carried out at 37°C, the rotation speed was 200 r / min, the ventilation rate was 0.5vvm, the pH value was not controlled during the fermentation process, and the fermentation was terminated when there was no residual sugar, and the fermentation liquid was obtained;

[0039] (3) Fermentation broth post-treatment

[0040] The fermentation broth was heated in a water bath at 65°C for 1 hour,...

Embodiment 2

[0042] Cordyceps militaris fermentation extract was prepared according to the method of Example 1, the difference being: glucose 5g / L and fructose 15g / L in the fermentation medium. The obtained Cordyceps militaris fermentation extract is recorded as Cordyceps militaris fermentation extract S2.

Embodiment 3

[0044] Cordyceps militaris fermentation extract was prepared according to the method of Example 1, the difference being: glucose 5g / L and fructose 20g / L in the fermentation medium. The obtained Cordyceps militaris fermentation extract is recorded as Cordyceps militaris fermentation extract S3.

Abstract

The invention discloses a preparation method of a cordyceps militaris fermentation extracting solution, an obtained product and application. The method comprises the following steps: performing fermentation culture on lactic acid bacteria in a fermentation culture medium taking cordyceps militaris as a nitrogen source to obtain the cordyceps militaris fermentation extracting solution. According tothe preparation method disclosed by the invention, by selecting proper strains and culture medium, microorganisms can utilize and decompose cordyceps militaris powder to the maximum extent to releaseeffective components; the content of cordycepin decomposed by the microorganisms is stable, and the content of cordycepic acid is increased by 6-8 times in comparison with that of an extraction method; and the extracting solution contains functional components of the cordyceps militaris and also contains some active substances generated by fermentation of the lactic acid bacteria, and the functional components and the active substances are combined for synergistic interaction, so that the nutrient substances, the nutrient density and the physiological activity of the cordyceps militaris fermentation extracting solution are greatly improved, the value of the cordyceps militaris fermentation extracting solution is far higher than that of cordyceps militaris or lactic acid bacteria fermentation extract, and the cordyceps militaris fermentation extracting solution is a natural high-quality skin care product, food or health care product raw material.

Description

technical field [0001] The present invention relates to a preparation method of Cordyceps militaris fermented extract, in particular to a method for preparing Cordyceps militaris fermented extract with lactic acid bacteria as the fermentation strain and in a fermentation medium with Cordyceps militaris as the only nitrogen source, and also relates to To the obtained Cordyceps militaris fermented extract and the application of the Cordyceps militaris fermented extract. Background technique [0002] Cordyceps militaris is the type species of Ascomycota, Hypocreas, Ergotaceae and Cordyceps. The scientific name is Cordyceps militaris, also known as Cordyceps militaris, Cordyceps militaris, referred to as Cordyceps militaris, and the Cordyceps militaris cultivated by living chrysalis is generally called Cordyceps militaris. Cordyceps militaris is distributed worldwide, and the natural resources are very few. The main active ingredients in Cordyceps militaris are cordycepin, cor...
