Three repellent coated PE film were development for avoiding storage insects and microorganisms. In this work, the microbiological and physiological properties of tetramethrin, cymperator and capsaicin-coated PE packing for rice grain were investigated. The results showed that the capsaicin-coated PE film was the optimal packaging material to preserve rice grain fresh. After three months storage of rice grain, capsaicin-coated PE inhibited the growth of bacteria and fungi than blank-coated PE, and had the similarly inhibiting roles than potent synthetic insecticide-coated PE packing. Especially, free fatty acid content increasing was decreased in storage of capsaicin-coated PE film, the flavor changes in slow.
