Water dispersed yeast β- Glucan is a bioactive substance with extensive application value. In order to achieve uniform molecular weight cutting and form uniformly suspended micro micelles, we adopted advanced membrane separation technology. Through membrane separation technology, we are able to precisely control yeast β- The molecular weight distribution of pectin, removing molecules that are too large or too small, ensures that its molecular weight reaches the ideal range. This technology not only improves the purity of the product, but also preserves its biological activity. The uniformly suspended micro micelle form enables yeast to β- Dextran is easily dispersed in water, making it suitable for further applications in fields such as food, cosmetics, and medicine. Water dispersed yeast β- Glucan and chitosan form adhesive facial mask material, which has obvious advantages in the field of drug delivery. Based on the morphology design of micelles, it achieves slow and controlled release, stable structure, and can reach deep skin layers.
