Abstract:In this study，the storage stability of tea seed oil was assessed under different temperature and gas environments and changes in its quality indicators were analyzed.The results showed that the structural stabil?ity of triglycerides in tea seed oil decreased and oxidation deepened under high temperatures.However，the acid value and peroxide value of tea seed oil after controlled atmosphere treatment by CO2 and N2 were signifi?cantly reduced，demonstrating that the controlled atmosphere treatment effectively inhibited the destruction of the triglyceride structure.In addition，the loss of tocopherols，oleic acid，and linoleic acid in tea seed oil was severe under high temperatures，while the controlled atmosphere treatment protected the above?mentioned ac?tive substances from being destroyed.Therefore，low?temperature and oxygen?free controlled atmosphere treat?ment will be important tools for quality control of tea seed oil.
