中文摘要: 采用傅里叶变换红外光谱法（fourier transform infrared spectroscopy，FTIR），以两种品牌不同年龄段的婴幼儿配方乳粉为例，进行红外光谱分析。研究表明，不同品牌和年龄段婴幼儿配方乳粉的红外光谱图比较相似，其中2 926、2856cm-1和1746cm-1处为脂肪特征官能团吸收峰，1 657 cm-1和1 541 cm-1处为蛋白质特征官能团吸收峰，3 383 cm-1、1 200 cm-1～1 029 cm-1和777 cm-1～769 cm-1处为碳水化合物特征官能团吸收峰，890 cm-1处为β糖苷键特征吸收峰。根据红外吸光度的差异，FTIR法可便捷的鉴别不同品牌和年龄段的婴幼儿配方乳粉，为相关生产型企业提供了快速鉴别的方法，具有借鉴意义。
Abstract:The fourier transform infrared spectroscopy（FTIR）was used to analyze the different ages infant and follow-up formula powder of two brand.Studies have shown that the infrared spectra of different ages infant and follow-up formula powder of different brands were similar，thecharacteristic functional group absorption peaks of fats were 2 926，2 856 cm-1and 1 746 cm-1，the characteristic functional group absorption peaks of proteins were 1 657 cm-1and 1 541 cm-1，the characteristic functional group absorption peaks of carbohydrates were 3 383 cm-1，1 200 cm-1～1 029 cm-1and 777 cm-1～769 cm-1，and the characteristic functional group absorption peak of beta-glycosidic bond was 890 cm-1.Based on the differences of infrared spectra，the method of FTIR is convenient to identify different ages infant and follow-up formula powder of different brands.This study provides a rapid identification method for the related production-oriented enterprises，which can be used for reference.
