It is a sugar present in nature and a functional oligosaccharide that can significantly promote the proliferation of bifidobacteria. Refined and extracted from plants, the pure product is a white powder with a slightly sweet taste and a sweetness of 22% of sucrose. The taste is pure and free from any adverse taste or odor. Stachyose has a significant proliferative effect on beneficial microbiota such as bifidobacteria and lactobacilli in the humangastrointestinal tract, which can quickly improve the environment in the human digestive tract and regulate the balance of microbiota. It can promote the formation of beneficial bacteria in the digestive tract, inhibit the production of spoilage bacteria such as Clostridium perfringens, and produce a large amount of physiological active substances, regulate intestinal pH, and decompose to derive multiple immune function factors.
