The invention provides a method for preparing a seaweed
fermentation solution by virtue of probiotics
fermentation and application of the seaweed
fermentation solution in preparing
cosmetics, which belongs to the technical field of microbial fermentation of seaweeds. The method comprises the following steps: (1)
superfine grinding seaweeds, and obtaining seaweed
powder with the
granularity of 1 to100 micrometers; (2) mixing the seaweed
powder and a bacillus fermentation solution, performing the primary fermentation, and obtaining a primary seaweed fermentation solution; (3) inoculating
saccharomycetes into the primary seaweed fermentation solution, performing the secondary fermentation, and obtaining a secondary seaweed fermentation solution; (4) inoculating
lactobacillus into the secondary seaweed fermentation solution, performing the
tertiary fermentation, and obtaining a
tertiary seaweed fermentation solution; and (5) standing the
tertiary seaweed fermentation solution at 8 to 12 DEG C, fermenting for 15 to 60 days, separating
solid and liquid, wherein the liquid component is the seaweed fermentation solution. The method is high in safety,
pollution-free, good in skincare effect and high in stability.
