This invention belongs to the field of cosmetic
raw material technology, and particularly relates to a
shea butter fermentation broth, its preparation method, and its application. This invention employs a specific ratio of *
Lactobacillus plantarum*, *
Lactobacillus fermentum*, and *
Lactobacillus gasseri* to construct a composite
fermentation system, combined with acid-resistant *
Aspergillus niger*
lipase, to process
shea butter through a one-step
fermentation process. Utilizing the synergistic effect of the three strains and the synergistic effect of the
enzyme and strains, not only is efficient fermentation achieved, significantly increasing the content of active ingredients such as polysaccharides, amino acids, and peptides in the
fermentation broth, but the process is also simple, stable, and avoids the risk of
contamination by other microorganisms. The
fermentation broth obtained by this process enhances the original moisturizing and soothing effects of
shea butter, effectively improving its oily feel and poor absorption, and further endowing it with new functions of repairing the
skin barrier and balancing the
skin microecology, greatly enhancing the application value of shea butter and its
fermentation broth.
