Beschreibung
Zusammenfassung:	The invention provides a preparation method of a pectin grafted copolymer, which comprises the following steps: mixing pectin, hesperidin and a solvent to obtain a mixed solution; mixing the mixed solution with horse radish peroxidase (HRP) in a water bath to obtain a mixed solution, and mixing an H2O2 solution with the mixed solution for graft copolymerization to obtain the hesperidin-pectin graft copolymer. An enzyme catalysis system (HRP and H2O2) is combined with graft modification, hesperidin pectin is used for graft copolymerization, in the graft copolymerization process, under the action of H2O2, the HRP can oxidize hesperidin into semi-quinone free radicals through single electrons, the semi-quinone free radicals participate in a grafting reaction and are connected with hydroxyl and hydrogen bonds on pectin chains, a graft copolymer is formed, and the hesperidin pectin grafted copolymer is prepared. The hydrogen supply or electron supply capability of the pectin is enhanced, so that the antioxidant ac
