| 摘 要： | 分别采用KNY/CPP,OPP/VMCPP和PET(SiO2)/CPP 3种材料对蛋糕进行包装,研究了3种包装材料透氧性对蛋糕油脂氧化程度的影响,并对包装材料下的氧化速率进行了表征,分别得到了3种包装材料酸价氧化速率拟合方程和过氧化值氧化速率拟合方程,证实了包装材料的透氧率与蛋糕的油脂氧化速率不能建立明确的数学关系。

| Abstract: | Three kinds of materials such as KNY/CPP,OPP/VMCPP and PET(SiO2)/CPP were used for packing cake.The influence of oxygen permeability of the packaging materials on grease oxidation degree of cake was studied and the oxidation rate under packaging status was characterized.The fitting equations of acid value and oxidation rate of these materials were obtained.The result showed that a clear mathematical relationship between oxygen transmission rate of materials and grease oxidation rate of cake cannot be established. |

| Keywords: | cake packaging material oxygen permeability oxygen transmission rate acid value grease oxidation peroxide value |
