Optimization of Ultrasound Method for Extraction of Apple Seed Oil

Using apple seed as material and Soxhlet extraction as control,the extraction of apple seed oil using ultrasonic sound was applied.The effect of extraction power,time,temperature,solvent volume and comminuted size on oil extraction was studied using ultrasound method.The result showed that the highest extraction oil rate could be obtained under the optimized conditions,the optimized conditions were:comminuted apple seed size 50 mesh,temperature 45 ℃,solvent /material 7:1(mL/g),ultrasound power 400 W and extraction time 30 min.The oil were mainly composed of unsaturated fatty acids with linoleic acid,oleic acid and palmitic acid being the major fatty acids.The three fatty acids accounted for 93 % of all the fatty acids combined.
