Description

Technical Field

[0001] The utility model relates to the technical field of fermentation product filtrate, in particular to a culture medium for preparing rice fermentation product filtrate. Background Art

[0002] In the existing rice fermentation product filtrate preparation technology, a specific culture medium is usually used to cultivate yeast, which ferments the starch and other ingredients in the rice into beneficial skin care ingredients. However, the prepared filtrate is prone to precipitation and stratification after long-term storage. In order to maintain the uniformity of the filtrate, it needs to be stirred before use. The traditional stirring method usually requires the use of a stirring device, which not only increases the carrying cost of the product, but is also relatively cumbersome during the operation process. The sealing of the prior art is insufficient, which easily leads to external bacteria entering the culture medium, which seriously affects the cultivation process of the filtrate. The invasion of external bacteria may cause contamination of the culture medium, thereby affecting the growth and fermentation efficiency of yeast. In addition, the contaminated culture medium may cause unnecessary impurities in the filtrate, affecting the quality and safety of the final product. In the laboratory and production environment, stacking the culture medium is a common operation, especially when conducting large-scale culture experiments. When stacking the culture medium, due to its shape and weight, it is easy to dump. The dumping problem may cause waste of the culture medium and may even cause laboratory accidents, affecting the experimental results and laboratory safety. Utility Model Content
