Abstract

Synchrotron Fourier transform infrared (FTIR) microspectroscopy as a rapid, direct, and non-destructive analytical technique can explore molecular chemical features of the micro-structure of biological samples. However, the application of this synchrotron technology to feed science and feed chemistry is extremely rare. This article reviews that with synchrotron FTIR microspectroscopy, the molecular chemistry of various feed tissues could be imaged. These images revealed spatial intensity and distribution of chemical functional groups in various feeds tissues within cellular dimensions. Such information can be used for plant breeding program for selecting superior variety of plant for targeted feed purposes and for prediction of feed quality and nutritive value. The final purpose of this article shows that Synchrotron FTIR microspectroscopy can be used for biological structure study.

摘要

同步辐射傅里叶变换红外（FTIR）显微光谱技术作为一种快速、直接且无损的分析技术，能够探究生物样品微观结构的分子化学特征。然而，这种同步辐射技术在饲料科学和饲料化学中的应用极为罕见。本文综述了利用同步辐射FTIR显微光谱技术，可以对各种饲料组织的分子化学进行成像。这些图像揭示了细胞尺度下各种饲料组织中化学官能团的空间强度和分布。此类信息可用于植物育种计划，以选择用于特定饲料目的的优良植物品种，并用于预测饲料质量和营养价值。本文的最终目的表明，同步辐射FTIR显微光谱技术可用于生物结构研究。
