Study on Antioxidation and Stabiliy of Ginger Oleoresin on Fat and Oil

Using ginger oleoresin as raw materials,this paper focused on antioxidation and stabiliy of ginger oleoresin on fat and oil.The results showed that when a certain quantity ginger oleoresin were added in oil,the antioxidation of oil were improved.But as the quantity enlarging,the system peroxide number decreased in descending extent.Generally,the suitable addition was 100 -150 mg/kg.The ginger oleoresin was stable under temperature 100 ℃,sunlight,acidic condition.However,it was not good in alkalinity,and could storage for long time.
