Different Refined Degree on Quality Changes of Camellia Seed Oil During Storage

In order to clarify the refined different degrees on qualities changes of camellia seed oil during storage and provide reference for the storage technology,the research has selected four refined different degrees camellia seed oils from one batch. The oils have been applied to research the variations of quality,the safety of indicators and physiologically active substances during storage. The results showed that the crude oil acid value increased by29. 85% which was the fastest growth speed. The alkaline oil had the slowest growth speed of acid value and peroxide value,with increasing by 3. 48% and 5. 97% respectively. The moderate refined degree helped to presence oleic and linoleic acids,VE and squalene. The VE and squalene of refined oil physiological activator were lost during storage.By comparison,there were more physiologically active substances in moderate refined oil. As a result,based on the good raw materials,moderate refining was feasible to ensure the quality during storage.
