PLA/TiO2纳米复合膜对香菇保鲜效果的研究
The preservation effect of polylactic acid nano-TiO2 composite film packaging on Lentinus edodes
摘要
Abstract
In order to study preservation effects of nano-composite materials to harvested Lentinus edodes,compared with unpacked ones,this article meaned to discuss the preservation effect of PLA composite films in which added different mass fractions of nanometer TiO2 (the TiO2 fractions:0％,1％,2％ and 3％) to Lentinus edodes.Lentinus edodes'physical and chemical indexes,as well as microbiological indicators,were measured every 4 days when storing at the temperature of(4 ± 1) ℃.The results demonstrated that polylactic acid nano-TiO2 composite film could better maintain the sensory quality,reduce respiration intensity and the loss of moisture,keep VC and reducing sugars contents of Lentinus edodes in storage period.The additive amount of nano-TiO2 was proportional to the preservation effect,and the preservation effect of polylactic acid with 3 percent fraction of nanometer TiO2 to Lentinus edodes achieved the optimal effect.关键词
