超声波辅助法提取亚麻籽油工艺研究

Research on the ultrasonic-assisted extraction technology of flaxseed oil

以亚麻籽为原料,在单因素试验基础上运用响应面试验优化超声波辅助法提取亚麻籽油的主要工艺参数(超声波温度、超声波时间和超声波功率)。结果表明:在超声波温度55℃、超声波时间50 min、超声波功率400 W的条件下,亚麻籽油提取率最高,为37.43%。影响亚麻籽油提取率的因素依次为超声波温度>超声波时间>超声波功率。通过气相色谱仪对提取的亚麻籽油进行成分分析,共鉴定出了37种脂肪酸成分。

Using flaxseed as raw material,on the basis of single factor,the main technological parameters(ultrasonic temperature,ultrasonic time and ultrasonic power)of ultrasonic-assisted extraction of flaxseed oil were optimized by response surface tests.Results showed that when the ultrasonic temperature was 55℃,the ultrasonic time was 50 min and the ultrasonic power was 400 W,the extraction rate of flaxseed oil was the highest(37.43%).The factors affecting the extraction rate of flaxseed oil were as follows:ultrasonic temperature>ultrasonic time>ultrasonic power.The components of extrected flaxseed oil were analyzed by gas chromatograph,37 different fatty acid components were identified.
