Abstract

The tomato processing industry causes high amount of waste mainly skin and seeds that creates the environmental problem. These residues are major source of bioactive compounds and valuable pigments. Hence the purpose of this study was to extract the lycopene content from tomato pomace using conventional organic solvent extraction (COSE) and ultrasonication assisted extraction (UAE) methods. The effect of operating conditions was determined by varying extraction treatment time, solid liquid ratio and power variation in UAE. The maximum yield of lycopene was obtained in UAE (160 V for ratio 50:1 for 15 min) as compared to COSE. FTIR analysis was performed for lycopene Extract. Beta carotene was also obtained in the lycopene enriched alcoholic extract and maximum yield was found to be in UAE at 50: 1 for 20 and 30 min at 180 V. Tomato oil was isolated from dried tomato seeds obtained from tomato pomace. GC analysis was performed to study fatty acid profile.
