超声波辅助提取苹果籽油的研究

Study on Ultrasonic Wave Extraction of Apple Seed Oil

应用超声波法提取苹果籽油,采用单因素和正交设计法研究了超声功率、超声温度、超声时间、物料粒度和溶剂用量对苹果籽油提取率的影响,研究结果表明,在超声强度为175W,超声温度为60℃,超声时间为30min,溶剂用量(液固比)为8mL/g,物料粒度为60目的条件下,苹果籽油平均得率为26.5%。

We have extracted apple seed oil by using ultrasound and studied the effect of the parameters, such as the power, the temperature and extracting time of the ultrasound as well as the particle size, solvent dosage on extraction rate by using the single factor and orthogonal design. The optimal technique conditions are： ultrasound power is 175W,ultrasound temperature is 60℃ , ultrasound extracting time is 30 min, particle size is under No. 60 screen net and solvent dosage （the ratio of solid and liquid ） is 8. In this way, the yield of the apple seed oil is 26.5 % on average.
