Abstract:
      The polyphenol content, vitamin E content, phytosterol content, squalene content, total flavonoid content, peroxide value and oxidative stability of oil-tea camellia seed oil produced by different processes (cold pressing, hot pressing, solvent-extraction and refining, fresh pressing) were determined so as to study the effect of oil preparation processes on the trace components and oxidative stability of oil-tea camellia seed oil. The results showed that the contents of polyphenol, vitamin E, phytosterol, squalene and total flavone in fresh-pressed oil-tea camellia seed oil was higher than those of the other three processes,the peroxide value of fresh-pressed oil-tea camellia seed oil was lower than that of the other three processes, and the oxidative stability of fresh-pressed oil-tea camellia seed oil was much higher than that of the other three processes.
