The physicochemical properties, functional group composition, moisture-preserving, and antioxidant ability were determined. The results indicate that the polysaccharide contents of PNP-40, PNP-60, and PNP-80 are 45.12%, 78.04%, and 72.22%, respectively, while the £]-glucan, protein, and uronic acid contents are 20.20%, 12.20%, and 10.15%, respectively; 11.24%, 14.53%, and 26.94%; and 5.99%, 7.73%, and 3.78%. Furthermore, PNP-60 has better moisture absorption, while PNP-80 has better antioxidant ability and H 2 O 2 -injury resistance activity. Monosaccharide composition analysis shows that P. nameko belongs to heteropolysaccharides, which consists of galactose, glucose, and mannose with different types and ratios, and the molecular weight are distributed at 4.40¡V333.49 kDa. It was found that different polysaccharide fractions have the potential to be a moisturizer and an antioxidant, and their active ingredients could be used in the development of cosmetic ingredients. ? 2019 Elsevier B.V. |
