Effect of Long-term Storage on Ac id Va lue and Perox ideVa lue of O il2tea Camellia Seed O il

The acid value and the peroxide value of standing storaged oil-tea camellia seed oil samp le under the roomtemperature and dark condition were determined. The results showde that under long-term storage condition, both theacid value and the peroxide value of oil-tea camellia seed oil samp les increased. The longer the time lasted , thequicker speed increased, and the easier the quality degraded. Under the same storage condition, for different purifiedsolvent extraction oil-tea camellia seed oil, the more purified, the more oxidized; for different p rocess techniques, solvent extraction was oxidized more easily than p ressed oil-tea camellia seed oil. So the temperature and time had greateffect on acid value and peroxide value of long-term storaged oil-tea camellia seed oil samp le.
