This invention discloses a method for preparing a composition with immune-enhancing effects and its application, belonging to the field of health product technology. The preparation method is as follows:
Astragalus membranaceus,
Lycium barbarum, and
Prunus cerasifera are ground into
powder to obtain premix A;
Cordyceps militaris and
Pleurotus ostreatus are washed, vacuum freeze-dried, and pulverized to obtain premix B;
Lemon myrtle leaves are cleaned, dried, and pulverized to obtain
lemon myrtle leaf
powder; Premix A, Premix B, and
lemon myrtle leaf
powder are mixed evenly, and deionized water is added and mixed thoroughly to obtain a
fermentation substrate; a mixed
bacterial agent is added to the
fermentation substrate for
fermentation; after fermentation, the fermentation liquid is refrigerated and sterilized, the supernatant is collected after
centrifugation and filtered, and then the filtered fermentation liquid is mixed evenly with concentrated apple juice and
yeast β-
glucan to obtain a composition with immune-enhancing effects. The composition of this invention can effectively activate the activity of immune cells in the body, enhance the body's resistance to pathogens, and improve the market competitiveness of the product.
