摘要
建立了一种对油脂皂化值进行快速有效检测的方法。以不同油脂的傅立叶自解卷积红外光谱图为依据,确定了不同油脂的皂化值与对应谱图中特征峰的关系,并根据特征峰的峰高和峰面积确立了通过谱图计算油脂皂化值的方法,实现了通过傅立叶自解卷积红外光谱法对油脂皂化值的测定。
Fourier transformation infrared spectroscopy-Fourier self-deconvolution（FTIR-FSD） technology was used for a rapid and simultaneous determination of oils saponification value（SV）.According to the FTIR-FSD spectra of oils,the relationship between the values and the absorbance bands in the spectra was investigated and the method was established for the determination of SV.The SV of oils could be calculated through the heights and areas of special absorbance bands.
