Abstract
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 reaction timewas 5.4 h and the pH was 9.2. Infrared spectroscopy suggested that thephosphorylation of FVSP was successful. Compared with FVSP, Ph-FVSP was morecapable of scavenging hydroxyl radicals and superoxide anions. Our resultsrevealed that Ph-FVSP had potential as a novel food additive and antioxidant inthe food industry.
