Optimization on Extraction Process Conditions of Lycopene in Tomato / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to optimize the extraction process conditions of lycopene in tomato. Ketchup was used as raw material. Method verification, single factor experiment and orthogonal method were used in the study on extraction process of lycopene. The results showed that the best optimization process conditions of lycopene extraction with ethyl acetate extraction temperature at 50℃, extraction time for 40 min, ethyl acetate concentration of 80%, solid-to-liquid ratio of 1?2 (g·mL-1). Under these conditions, the extraction rate of lycopene reached 15.564 mg·100g-1. It was concluded that the extraction process of lycopene can provide experimental basis for further development and utilization of lycopene.
