活化能

Results of kinetic study of the degradation process of anthocyanins in Myrica rubra juice suggeste that the degradation process is a first order degradation kinetic process. As the increase of temperature and pH value, the half-life degradation of anthocyanins and activation energy for the thermal degradation decrease significantly. Under the same condition, the half-life of concentrate is significantly lower than that of the juice.

花色苷降解动力学数据的分析结果表明：杨梅花色苷热降解属动力学一级反应，随着pH值和温度的升高，杨梅花色苷降解的半衰期(t 1/2)和热降解活化能显著下降，即花色苷的降解速度增大；同一处理条件下，浓缩果汁的 t 1/2明显低于澄清汁。

Analysis also indicate that activation energy of degradation in compound-stabilizer systems are considerably greater than others, among these POM/COPA/EVOH48 has the highest activation energy reaching220.19 KJmol-1 in nitrogen which is three times the value of blank POM (77.74 KJmol-1), and 530.37 KJmol-1 in air which also exceeds the blank POM (354.59KJmol-1) by fifty percent.

分析结果还表明复合稳定剂体系的活化能要明显高于其它体系。
