【摘要】 本实验通过超声波辅助提取辣木油的正交试验,研究了影响辣木油提取的主要因素,以及辣木油超声波辅助提取的最佳萃取工艺。结果表明,在提取次数2次、提取时间40min、超声波频率28kHz、液料比8:1(V/m)的条件下,辣木油平均得率为35.85%(占辣木种子含油率的96%)。更多还原

【Abstract】 In this study, ultrasonic was used in petroleum ether extraction process of Moringa oleifera seed oil. The effects of four primary factors such as petroleum ether l to raw material ratio (V/W), extraction time, extraction times and ultrasonic frequency on the extraction yield of Moringa oleifera seed oil were investigated in single factor test, and then based on the results of single factor test, orthogonal test was designed to optimized the four factors. The results showed that the optimal petroleum ether l to raw material ratio, extraction time, extraction times and ultrasonic frequency are 8:1 (ml/g), 40 min, 2 and 28 kHz, respectively. Under these conditions, the yield of Moringa oleifera seed oil is 35.85%, which accounts for 96% of the total oil content of Moringa oleifera seed.更多还原
