摘 要: 采用功率超声(频率为20 kHz,功率密度为345 W/cm2)处理和微波(375 W)处理花生油,并用气-质联用色谱(GC-MS)分别检测了未经物理场处理和物理场处理的花生油脂肪酸组成及其相对含量。结果表明,超声和微波处理对花生油的脂肪酸组成和相对含量有一定影响,但影响不显著。 The effects of high power ultrasonic treatment(20 kHz,345 W/cm^2) and microwave treatment(375 W) on components of refined peanut oil sample were studied via detecting the change of fatty acid composition and relative content by gas chromatography coupled to mass spectrometry(GC-MS).The results indicated that the high power ultrasonic and microwave had some effects on fatty acid composition for treated peanut oil sample, but no significant changes were observed.
