| Abstract: |
| Taking Acer truncatum seed oil as the raw material and the peroxide value (POV), acid value (AV) and 2-thiobarbituric acid (TBA) value as indicators for its oxidation stability, the effects of storage conditions such as temperature, light, air, bottle material and color on the oxidation stability of Acer truncatum seed oil were studied. The oxidation kinetic model was further established to predict the shelf life of Acer truncatum seed oil. The results showed that under storage conditions of low-temperature, light-proof, oxygen-free and with packaging materials of stainless steel, ceramics, or glass tinted in blue/green, the POV, AV and TBA values of Acer truncatum seed oil only grew very slowly, showing strong oxidation stability. The oxidation process followed the zero-order reaction kinetics, and the POV matched the predicted values according to the kinetic model. The shelf life of Acer truncatum seed oil under sealed and dark storage conditions was estimated to be 516 d and 335 d at 20 ℃ and 25 ℃, respectively. |
