Abstract: Lycopene is a kind of functional natural colorants,it has many physiological function,antioxidation,anti-cancerr,enhancing immune ability and so on.The extraction of lycopene with organic solvents at the varied temperature,time and solid to liquid ratio was investigated.The optimized process conditions of extraction of lycopene from fresh carrot was the extraction effect with ethyl acetatewas the best, so ethyl acetatewas selected as the extraction solvent.The optimum extraction technology for lycopene was that liquid-to-solid ratio of 2:1(ml/g), extraction time of 100min, extraction temperature of 35℃.The method had advantages of low cost,high efficiency and easy to automatization,thus having broad industrialized application prospects.
