Research ArticleOpen accessPhrase in the titlePhosphorylation, Characterization, and Antioxidant Activity of Polysaccharides from Flammulina Velutipes ScrapsYingyun Peng, Xue Bai, Hanwen Xu et al.In this study, polysaccharides from Flammulina velutipes Scraps(FVSP) were extracted. The preparation conditions of the Phosphorylated derivativeof FVSP (Ph-FVSP) were optimized based on single experiments and responsesurface analysis. Characterization and antioxidant properties of FVSP andPh-FVSP were investigated. The optimum phosphorylation modification process ofFVSP obtained was as follows: The mass ratio of STPP/STMP was 1:2, the reaction temperature was 70℃, the … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 16 Aug 2022 · 6,007 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titlePreparation, Characterization and Antioxidant Activity of a Novel Acetylated Polysaccharide from Flammulina VelutipesYingyun Peng, Han Jiang, Yufeng Wu et al.In this study, a novel polysaccharide FVP2a wasextracted and purified from F. velutipes. Ac-FVP2a was prepared bychemical acetylation. The preparation process of Ac-FVP2a was optimized usingthe response surface method based on three experimental factors includingreaction time, reaction temperature, and the ratio of FVP2a to aceticanhydride. The physicochemical characteristics andantioxidant activities of Ac-FVP2a in vitro were investigated. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,207 accessesView PDF Cite
