Abstract: This article is focuses on new antioxidant polymer composites Synthesis fresh light on the film, as well as walnut nuts in storage during the acid value, peroxide value of sensory evaluation analysis, research film Walnut Kazakhstan on the inhibitory effect of metamorphic failure in order to prolong their shelf life. These study ordinary about pecan. For coating of walnut, the study found that in the storage of walnut nuts, the use of a new type of vacuum antioxidant polymer composite light preservative coating, can be inhibited to some extent, the Kazakh defeated Walnut nuts. Polymer composites in new antioxidant compound light preservative formulations research, this study mainly instant starch at how to natural tea extracts thearubigins, antioxidant synergist Vc and citric acid as the main raw materials research. Research as a walnut nuts bright antioxidant preservative, as well as the best ratio of its way to trial. Through experiments, coating of walnut nuts for the best formula: instant starch 5% + Vc0.015% + citric acid 0.02% + 0.005% thearubigins.
