Paper Title:
Synthesis and the Characterizations of Structure and Function of Gallic Acid Microcrystalline Cellulose Ester
  Abstract

In order to solve the toxicity problem of gallic acid and its esters as food antioxidant,using the advantages of microcrystalline cellulose security and not to be absorbed by the body, a new type of polymeric anti-oxidants was exploited. Gallic acid microcrystalline cellulose ester was prepared by indirect esterification method ,which gallic acid and microcrystalline cellulose were used as raw materials. The structures of reaction materials and products were characterized and its oxidation resistance, stability, acute toxicology were studied by infrared spectroscopy, X-ray diffraction spectroscopy, scanning electron microscopy .The results showed that: gallic acid microcrystalline cellulose ester was successfully synthesized ; its ability to remove all kinds of free radicals was higher than or approximate equal to gallic acid; suitable for room temperature storage, high temperature sterilization, ultraviolet sterilizer, pH3.0~9.0,under these conditions it was stability;it was non-toxic substance, the safety was higher than gallic acid and gallic acid propyl. This study established the technical foundation for the further development of a new type of functional macromolecular compound which could be used for antioxidation.
