LDPE／SiO2保鲜膜保鲜果蔬

Fresh-keeping Membrane of LDPE and SiO_2 for Vegetables and Fruits

为了更有效的保鲜新鲜水果,鉴于低密度聚乙烯薄膜(LDPE)存在的缺点,采用无机矿物二氧化硅(SiO2)填充LDPE薄膜包装新鲜果蔬。试验结果表明LDPE/S iO2膜能有效的抑制果蔬的呼吸强度、延缓果蔬衰老,具有良好的保鲜效果。

Mineral silicon dioxide （ SiO2 ） packed low density polyethylene （LDPE） was applied to preserve fruits and vegetables. Tests showed that LDPE/SiO2 membrane can effectively restrain the respiration intensity of fruits and vegetables to slow their senescence, and has good fresh-keeping effect.
