| 摘 要： | 为了减小超市灯光中紫外线对包装鲜切西兰花的货架寿命的影响,采用LDPE与紫外线吸收剂UV-531共混的方法制备选择性阻光薄膜,UV-531所占质量分数分别为0,0.1%,0.3%和0.5%。使用制备的4种薄膜和超市现用LLDPE保鲜膜包装鲜切西兰花,置于超市用灯光下进行保鲜研究。结果表明:添加紫外线吸收剂的LDPE薄膜的透光率随着紫外线吸收剂添加量的增加而降低;在室温(29+1)℃条件下,添加紫外线吸收剂的LDPE薄膜对鲜切西兰花的保鲜效果均好于超市现用LLDPE保鲜膜;其中添加量为0.3%时能够更好地保护鲜切西兰花的叶绿素和水分,保鲜效果最好。

| Abstract: | The purpose of this research is to reduce the effect of UV on shelf life of packaged broccoli in supermarket.Selective anti-light packaging films were prepared using LDPE and UV absorber UV-531 by blending method,which has UV-531 proportion of 0,0.1,0.3,and 0.5 percent respectively.The prepared films and current used LLDPE film in supermarket were used to pack broccoli and exposed under supermarket light for preservation research.The result showed that the transmittance of the LDPE film decreases with incre... |
