The extraction of lycopene from dried tomato
powder was carried out using ultrasound assisted (UAE) and conventional solvent
(COSE) extraction methods with varying liquid/solid ratio (10:1-50:1),
extraction time (5-60 min), temperature (20-50°C) and ultrasonic
power (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 (722.321 mg lycopene/kg
tomato powder) and COSE (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.
