Effect of endogenous VE on oxidation state during fat storage under different temperature

In order to investigate the effect of endogenous V E on oxidation state during fat storage under different temperature, the postmortem endogenous V E, POV and TBARS of bovine adipose stored under-18, 0, 20℃ for120h from eight simmental cattle were determined.The maximal increase of POV and TBARS was found under 20℃after storage for 120h which was 1.20 times and 1.65 times of 0℃ respectively, and was 1.84 times and 1.94 times of-18℃ respectively. With corresponding oxidation state, the maximal decline of endogenous V E was also found under 20℃ with residual rate of 21% at 120h, which was 62.5% and 70.4% lower than 0°C and-18°C respectively.There was a significant negative correlation between V E and POV with correlation coefficients ranged from-0.920 to-0.997, and between V E and TBARS with correlation coefficients ranged from-0.946 to-0.983.It was showed that the low temperature condition could decelerate the increase of POV and TBARS of bovine adipose during storage which was closely related to significant negative correlation.
