【Abstract】 Objective To study extractive method of lycopene from tomato sauce . Methods To focuse on the different factors in the extraction of lycopene with ultrasonic radiation from tomato sauce. Results The best process conditions were fi xed by using the orthogonal test : acetone: petroleum ether=2:3(v/v) as the extraction solvent , the output power was 250 W , the temperature was 35 ℃,ratio of material and liquor was 1:3(g/mL), radiation lasted 30 minites, the extraction stage was 3 grade, and the extraction yield of total pigment was 95.92%. Conclusion The content of the product was 17.9% deteced by HPLC.更多还原
