Lycopene green ultrasound-assisted extraction using edible oil accompany with response surface methodology (RSM) optimization performance: Application in tomato processing wastes

Abstract

Tomato paste processing wastes, a significant paste industry by-product, is plentiful in conceivably health-supporting compounds, for instance, lycopene. Lycopene is an ultra-high content nutraceutical while its separation from food industrial waste is frequently appropriate to enhance proceeds. This exploration reports on the lycopene extraction from wastes of tomato processing based on an ultrasound-assisted performance exploiting sunflower oil as a green solvent with response surface methodology (RSM) while it was compared with conventional organic solvent extraction procedure. Three independent variables were ultrasonic intensity (30–70 W/m2), solid/oil ratio (3.18–36.82% w/v), and the extraction time (1.59–18.41 min) and the samples lycopene contents were assessed via spectrophotometric technique. According to the consequences, the optimum ultrasound-assisted extraction (UAE) situation was accomplished with 70 W/m2 ultrasonic intensity of and 10 min extraction time. The solid/oil ratio is not a substantial parameter on the yield of extraction. The current developed, UAE of lycopene from tomato wastes with the RSM assistance correspondingly developed the lycopene extraction yield by 87.25% contrasted to conventional solvent extraction (CSE). Sunflower antioxidant activity the oil containing extracts was assessed by the acid determination, peroxide and p-anisidine content during three weeks at 60 °C. Furthermore, the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging was attained. The consequences exposed that most of the samples offered considerable recovers in acid dosage compared to sunflower oil without antioxidant. Instead, substantial reductions in peroxide and p-anisidine were apparent in the oil samples treated with the tomato extracts in comparing with the control.
