Abstract :The extraction of lycopene from dried tomato powder was carried out using ultrasound assisted insert ignore into journalissuearticles values(UAE); and conventional solvent insert ignore into journalissuearticles values(COSE); extraction methods with varying liquid/solid ratio insert ignore into journalissuearticles values(10:1-50:1);, extraction time insert ignore into journalissuearticles values(5-60 min);, temperature insert ignore into journalissuearticles values(20-50 ° C); and ultrasonic power insert ignore into journalissuearticles values(150-200 W);. The response surface methodology was used to optimize the extraction parameters and to determine their individual and interaction effects on the extraction yield. The maximum extraction yields of UAE insert ignore into journalissuearticles values(722.321 mg lycopene/kg tomato powder); and COSE insert ignore into journalissuearticles values(975.833 mg lycopene/kg tomato powder); was observed using the following conditions: 166 W for 26 min, and a 56:1 liquid/solid ratio, and 45 ° C for 50 min, and a 56:1 liquid/ solid ratio, respectively. At the same extraction conditions UAE is reaching the same extraction yield faster than the COSE. Even the lycopene contents of the extracts were the same, the antioxidant capacity of the UAE and COSE extracts were 12.48 and 11.08 mg Trolox/g tomato powder, respectively .
