  • Abstract:
  • Oil content in the seeds is between 35-40% and the unsaturated fatty acid content in oil is 78-86% predominantly linoleic acid (45-73%). Soxhlet extraction is the most common technique for oil seed extraction. Watermelon seed oil is obtained from date seed through Soxhlet extraction technique. % Yield and recovery of Oil using solvent extraction with different feed to solvent ratio. For solvent petroleum ether shows 1:3, 1:4 and 1:5 seed powder to petroleum ether ratio the % yield 32 %, 35% and 37 % resp. For solvent petroleum ether shows 1:3, 1:4 and 1:5 seed powder to petroleum ether ratio the % recovery 80 %, 87.5 % and 92.5 % resp. As per observation petroleum ether is the best suitable for extraction of oil from the watermelon seed. petroleum ether can easily separate after extraction and has higher yield than other with low cost. The ration of feed to solvent also important factor to be consider for extraction process which effect on the yield of oil. The optimum value for feed to solvent is 1:4 on which maximum yield for watermelon seed oil extraction. As the feed to solvent ration increase more than 1:4 there is appreciable change in the yield but the cost of solvent increase. The 1:4 feed to solvent ration is to be optimum value for watermelon seed oil extraction. The time of extraction increased yield of oil also increase and up to maximum level. The extraction of date seed oil carried out 1.5-2.5 hrs. Ihe optimum time for extraction is 2 hrs. Crushed seed in powdered form gives large surface area for solid-liquid contact. Due to small size particles increase rate as well as yield of extraction of oil from watermelon seed. Extraction carried out at boiling temperature of solvent should be better for rate and yield of extraction. Temperature for extraction with petroleum ether up to 35-40 OC.
