摘 要: 利用微波加热了 4种精炼植物油 ,分别以过氧化值或硫代巴比妥酸值作为一级或二级氧化产物的指标 ,对油脂的质量进行评价 .研究表明 ,表征植物油酸败程度的化学指标随微波参数和油脂种类的不同而有较大变化 ,并且辐射周期越长 ,油脂的氧化稳定性越差 . Four kinds of refined vegetable oils were heated by microwave. The research focused on the evaluation of the oils based on the quality assurance method (peroxide value or thiobarbituric acid va_lue) as an indicator for the primary or se_condary oxidation products, respectively. It was shown that the chemical indexes indicating deterioration of vegetable oils could be significantly affected by the heating parameter of microwave and the sorts of oils. And, the stronger the irradiating period, the poorer the oils' oxidative stability.
