为了快速准确地鉴别天然肠衣,为天然肠衣提供可靠快速的检测手段。采用红外光谱法对天然肠衣进行测定,通过比较天然肠衣和样品肠衣的红外谱图的相似性和特定谱峰相似性,对样品肠衣的真伪进行鉴别。天然肠衣在3296、2961、2927、2852、1663、1558、1457、1403、1339、1240、1083、675cm-1处有较强的特征吸收峰。根据谱图对比分析和特征谱峰相似性能快速确定样品肠衣的真伪,红外光谱法可以作为天然肠衣真伪鉴别的一种快速检测方法。
In order to quickly and accurately identify the natural casing, for natural casings provide reliable and rapid detection means. The natural casing was determined by infrared spectroscopy. The authenticity of the sample casing was identified by comparing the similarity of the infrared spectra of the natural casing with the sample casing and the similarity of specific peaks. Natural casing in 3296,2961,2927,2852,1663,1558,1457,1403,1339,1240,1083,675cm-1 at a strong characteristic absorption peak. According to the spectral contrast analysis and the similarity of the characteristic peaks, the authenticity of the sample casings can be quickly determined. The infrared spectroscopy can be used as a rapid detection method for the authenticity of natural casings.
