Abstract
The subject use pumpkin seed as raw material,Soxhlet extraction method with a pumpkin seed oil content of about 64%,and then use temperature,time,liquid ratio as factors to study the various factors on the rate of oil by the orthonormal table L9(33)method.The result showed that the optimum extraction Conditions were extraction temperature 60℃,time 4h,liquid ratio 1:10(W:V)and extraction ratio reached to 83.88%.While the physical and chemical properties of pumpkin seed oil were yellow green,opaque,with aroma,acid value 1.88mg/g,iodine value 123g/100g,peroxide value of 12.6g/100g.
