This invention relates to the field of
biomedical technology, specifically to a method for preparing a fermented product of soybean extract, an anti-aging composition, and its applications. The preparation method includes: pulverizing soybean raw materials, adding water, and then performing microfluidic pulverization; followed by
enzymatic hydrolysis with hydrolytic enzymes and
inoculation with
Lactobacillus for
fermentation; and finally, separating the
solid and liquid components to obtain a
Lactobacillus / soybean extract
fermentation product filtrate for sterilization. The anti-aging composition of this invention comprises the above-mentioned
fermentation product filtrate, as well as
lilac extract and wild rose fruit extract. This invention is the first to discover that the
Lactobacillus / soybean extract fermentation product filtrate, when combined with
lilac and wild rose
fruit extracts, exhibits a significant synergistic effect in promoting
cell repair, inhibiting
inflammatory factors, and providing
antioxidant benefits. Furthermore, this synergistic network is component-specific and can be widely used in the preparation of
cosmetics with anti-aging,
skin repair, and anti-inflammatory soothing effects.
