    Utilization of seed from tomato processing industry for extraction of oil
    (Chaudhary Charan Singh Haryana Agricultural University hisar, 2022-12) Nirmala; Attkan, Arun Kumar
    The study was conducted for utilization of seed from tomato processing industry for extraction of oil. The tomato waste was dried to a moisture content of 7% (wb.). Seeds were separated using hammer mill and gravity separator. The two oil extraction techniques, temperature controlled water bath, ultrasound assisted solvent oil extraction method. The process parameters for TCWBM were extraction temperature (20, 25 30℃), extraction time (6, 8, 10min), solid to solvent ratio (1, 5, 10) and mean particle size (0.25, 0.55, 0.85mm). The process parameters for UASOEM were extraction temperature (40, 50 60℃), ET, extraction time (25, 35, 45min), solid to solvent ratio (5, 7.5, 10) and mean particle size (0.25, 0.55, 0.85mm). RSM was employed for optimizing the process parameters. The effect of process parameter was seen on oil yield, extraction efficiency and oil quality (API0). Maximum OY of 25.47%, EE of 93.1% and API gravity of 26.18 was found for UASOEM. RSM was employed for optimization of process parameters. The optimum process parameters for TCWBM obtained were 30˚C, 8min, 4.6 and 0.25mm of mean particle size and optimum OY of 14.48%, EE of 58.42% and API gravity of 24.93, with the desirability of 0.79 and for UASOEM obtained were 49.7˚C, 38.7min, 6.3 and 0.42mm of mean particle size and optimum OY of 18.20%, EE of 86.36% and API gravity of 26, with the desirability of 0.80. The cost economics of oil extraction was evaluated on the basis of economic indicators viz. breakeven point (313.4litre), payback period (0.8yr/ 9 months, 18days) and operating cost of (790 Rs./liter) of tomato seed oil at selling price of Rs. 1500/liter. The physicochemical properties such as density, specific gravity, saponification value, iodine value, color, sulfur content and fat content of oil were analyzed. It can be concluded that tomato seed is a potential source of oil. It will minimize the problem of utilization of tomato processing waste.
