This invention discloses a natural
selenium-enriched black
soybean sprout endogenous synergistic extract, its preparation method, and its applications, belonging to the fields of
food biotechnology and functional foods. Using high-
selenium naturally enriched black soybeans as a single
raw material, with no exogenous
selenium added throughout the process, anthocyanins are enriched through light-protected
germination. This is combined with
enzymatic hydrolysis and membrane separation purification to construct a multi-component endogenous synergistic
system. The extract is rich in highly converted organic selenium,
small molecule peptides, anthocyanins, and endogenous
phytase, exhibiting characteristics such as resistance to
gastric acid, slow release into the intestine, and promotion of
mineral absorption. Relying on the synergistic effects of multiple metabolic regulatory pathways, the product can achieve liver protection and detoxification,
cell repair,
antioxidant effects, and
fat reduction. It effectively improves the shortcomings of traditional compound products, such as weak stability, low
absorption rate, and large batch-to-batch variations. The production process is stable, with significant industrialization advantages, and it can be widely applied in the fields of functional foods, special dietary foods, and dietary supplements.
