Fractionation of Simulated Digestive Products of Bird’s Nest In Vitro: Skin Whitening Activity of Fractions

Figure 1

Whitening activity and physicochemical properties analysis of digested EBN during gastrointestinal digestion. (a) Tyrosinase inhibition of products with different gastric digestion times; (b) tyrosinase inhibition of products with different intestinal digestion times; (c) salivary acid level during gastrointestinal digestion; (d) molecular weight distribution of EBN digestive juices. Values with different letters are significantly different between the same curves ( < 0.05).
