The Study of Extraction and Antioxidation on Lycopene

Lycopene crystals were extracted from fresh tomato by recrystallization.HPLC detected The concentration of lycopene crystals were 99.1%.The stability of lycopene was determinated in 4 kinds of oil.At the same time,different antioxidants was compared wish the ability of antioxidant.The results show that the stability of lycopene was best in Soybean oil.With the increasing of the concentration of lycopene,its antioxidant ability was increased.The antioxidation of lycopene was highest in lycopene、vitamin E and Citric acid.
