Abstract

Lycopene is a natural and dominant pigment in tomato with coloring and antioxidant properties, which nowadays the demands for its extraction enhancement from tomato and tomato products are increasing. In this study, the effect of pectinase enzyme pre-treatment at 2- 10 ml/kg and also washing with 94% ethanol at 60°C for 5 seconds was studied. In these conditions, treating with 10 ml/kg enzyme concentration at 90 minutes effective time resulted in maximum extraction of lycopene (279.5 mg/100g oleoresin) while for samples treated with pectinase and ethanol, maxmum extraction was 160.87 mg/100g olearesin. Also lycopene extraction yield from 100 g sample was 0.113609 and 0.089478 mg respectively. Totally in this study it was shown that pectinase treatment without ethanol treatment for extraction of lycopene is better in tomato waste.
