Description

Technical Field

[0001] The present invention relates to the technical field of probiotic fermented beverages, and specifically to a formula for cordyceps militaris probiotic fermented beverage and a preparation method thereof. Background Art

[0002] Cordyceps militaris is a fungus of the family Clavicipitaceae and the genus Cordyceps, and is also an edible and medicinal fungus. Its protein content is as high as 40.7%. The essential amino acids contained in it are not only complete in variety, sufficient in quantity, but also appropriate in proportion. Cultivated cordyceps militaris also contains rich vitamins and minerals, etc., and has good edible value, so it is a relatively good economic crop;

[0003] A large number of microbial populations inhabit the human intestine, and among them, probiotics play a crucial role in human health. Probiotics can decompose food components that cannot be decomposed by the upper digestive system, produce short-chain fatty acids, and provide nutrients for gastrointestinal mucosal cells. At the same time, for certain components of oral drugs, especially natural drugs, they can be decomposed and metabolized, and the precursor substances of the drugs can be converted into active drug components to play a role;

[0004] Patent No. CN106551378A discloses a composition of probiotic-fermented cordyceps militaris and a preparation method thereof. The composition is obtained by crushing cordyceps militaris into cordyceps militaris powder, soaking it in water, adding glucose, peptone, yeast extract, yeast powder, inorganic salts, sweeteners, sterilizing, and then performing probiotic fermentation treatment, and adding polydextrose and oligofructose syrup to obtain the composition of probiotic-fermented cordyceps militaris. The fermented composition prepared by the present invention can be used to prepare health products or beverages for improving respiratory diseases, tonifying the lungs and kidneys, regulating the balance of intestinal flora, and improving gastrointestinal function. The present invention directly adds cordyceps militaris to the probiotic fermentation medium, extracts its active ingredients by high pressure and high temperature, improves the utilization rate of cordyceps militaris, and makes the active ingredients of cordyceps militaris become active substances that are easily absorbed by the intestine. It has been proven by experiments that it has a significant effect on improving respiratory diseases, tonifying the lungs and kidneys, regulating the balance of intestinal flora, and improving gastrointestinal function.
