preparation example Construction
[0015] The present invention relates to a kind of preparation method of black sesame mycelia fermentation liquid, comprising:
[0016] The black sesame strain is cultured in inclined test tubes to obtain mycelium blocks, and the mycelium blocks are inoculated on plate medium for mycelial culture, then transferred to malt medium, and cultured in liquid fermentation at 25-29°C for 4-7 days.
[0017] Preferably, if the purpose of preparation is to obtain the fermented liquid of black sesame mycelium with the most polysaccharide content, then the liquid fermentation is cultivated for 4 days; if the purpose of the preparation is to obtain the fermented liquid of black sesame mycelium with the highest content of triterpenes, then the liquid fermentation is cultivated for 6 days; If the preparation purpose is to obtain the black sesame mycelia fermentation liquid with the best antioxidant effect, the liquid fermentation culture is 4 days; if the preparation purpose is to obtain the bl...
