Optimization of Extraction Process for Lycopene from Rhodotorula glutins

Abstract

Abstract: Cell wall disruption followed by organic solvent extraction was used to extract lycopene from Rhodotorula glutins. The optimal cell wall disruption method and extraction solvent were found to be hot acid treatment and acetone-ethyl acetate (1:1), respectively. Three extraction conditions such as material-to-liquid ratio, temperature and time were optimized by orthogonal array design to be 1:60 (g/mL), 30 ℃ and 3 h, respectively. Under these conditions, the extraction rate of lycopene was 4.55 mg/g, 41.30% higher than before optimization.
