Cordyceps militaris two-way fermentation liquor as well as preparation process and application thereof

The invention relates to cordyceps militaris bidirectional fermentation liquor as well as a preparation process and application thereof, and belongs to the technical field of biological fermentation and cosmetic application. According to the invention, through research on six cordyceps militaris-traditional Chinese medicine combined bidirectional fermentation broth, better combinations and proportions are screened out, the cordyceps militaris-liquorice fermentation broth is obtained by adding liquorice into a cordyceps militaris fermentation medium and carrying out fermentation culture, the addition amount of the liquorice is 1-10g/100mL of the fermentation medium, the obtained cordyceps militaris-liquorice fermentation broth contains higher polysaccharide and polypeptide components, and the cordyceps militaris-liquorice fermentation broth is suitable for large-scale production. The composition has obvious anti-oxidation, anti-inflammatory, anti-wrinkle and tightening effects, is high in safety and wide in ap
