Abstract

The bioactive compound of tomato waste from industry was microwave-assisted extracted in different conditions including microwave powers of 180 300 and 450 W and the extraction time of 30 60 and 90 s. After extraction the fractionation was performed to separate the hydrophobic fraction (hexane fraction) and hydrophilic fraction (ethanolic fraction). The bioactive compound and its DPPH radical scavenging activity were determined. For the hydrophobic part the results showed that the microwave power of 300 W for 60 s gave the highest trans-lycopene and beta-carotene (5.74 mg lycopene/100 g and 4.83 mg beta-carotene/100 g) while the highest DPPH radical scavenging was the extracts at a microwave power of 180 W for 90 s. For hydrophilic parts the best extraction condition giving the highest total phenolic compound (280.10 mg GAE/100 g) and total flavonoid content (9832.52 mg CE/100 g DM) were at 180 W for 90 s and 450 W for 30 s respectively. However the highest antioxidant activity was the extract of 300 W for 60 s. Fuzzy assessment analysis exhibited that the best condition was microwave power of 300 W for 60 s with high antioxidant activity of both fractions.
