| Wild papaya seed was taken as raw material and the ultrasound- assisted extraction technology was used to extract wild papaya seed oil. The single factor experiment and orthogonal experiment were adopted to study the optimal extraction conditions. The results showed that the optimal extraction conditions of wild papaya seed oil were obtained as follows: with n-hexane as extraction solvent, ratio of solid to liquid 1∶5, ultrasonic temperature 30?℃, ultrasonic time 40 min and ultrasonic power 210 W. Under the optimal extraction conditions, the yield of wild papaya seed oil was 28.27%. The quality of wild papaya seed oil was good with golden color, clarification, high transparency and fragrant smell of wild papaya. The relative density(d204), refractive index（20?℃）,saponification value, iodine value, acid value and peroxide value were 0.896 9±0.01, 1.466 5±0.01, (182.0±1.87) mgKOH/g, (90.0±0.55) gI/100 g, (2.7±0.02) mgKOH/g and (0.018±0.03) g/100 g, respectively. The acid value and peroxide value of wild papaya seed oil accorded with the national standard of edible vegetable oil. So papaya seed oil had certain developing future. |
