摘　　要：应用傅立叶红外光谱中的自解卷积技术建立了快速测定油脂皂化值的检测方法,确定了不同油脂的碘价与对应红外光谱谱图中特征峰的关系,建立了相应的数学计算模型,并根据特征峰峰高和峰面积的计算结果对该模型进行验证,并最终确立通过傅立叶自解卷积红外光谱图对油脂碘价的快速测定方法。Fourier transformation infrared spectroscopy-fourier self-deconvolution（FTIR-FSD） technology was used for a rapid determination of oils iodine value（IV）.According to the FTIR-FSD spectra of oils,the relation-ship between the values and the absorbance bands was investigated.Finally,a rapid method for the deter-mination of IV was established.
