波谱技术在香蕉淀粉及抗性淀粉研究中的应用

淀粉是由葡萄糖分子聚合而形成的天然高分子化合物，不同来源的淀粉其结构也不尽相同。波谱技术具有检测灵敏度和准确度高、分析特征性强、非破坏性等特性，因此在研究淀粉结构方面得到广泛应用。目前利用波谱分析技术对抗性淀粉结构和性质等方面的研究鲜有综述报道，因此本文以富含抗性淀粉的香蕉为对象，概述了紫外-可见吸收光谱、红外吸收光谱、核磁共振、质谱以及X-射线衍射这些波谱技术的应用情况。首先对这些波谱技术的基本原理和应用特点进行了归纳，其次阐述了其在香蕉淀粉及抗性淀粉的直链淀粉含量、分子结构、晶型、结晶度等方面的应用。期望为应用波谱技术研究淀粉及抗性淀粉提供参考。

Applications of Spectrum Analysis in Banana Starch and Resistant Starch

Starch, a natural polymer compound, is formed by glucose molecules. The structure of starch from different sources is not same. Spectral technology has been widely used in the researches of starch structure because of its high sensitivity and accuracy, strong characteristic and non-destructive properties. Currently, the reviews on structure and properties of resistant starch (RS) by spectrum analysis are rarely reported. Therefore, the objective of this review is to summarize the applications of ultraviolet-visible absorption spectra, infrared absorption spectra, nuclear magnetic resonance, mass spectrometry and X-ray diffraction in banana resistant starch (BRS). Firstly, the principles and characteristics of each spectrum analysis technique are outlined. Then, their applications in the researches of amylose content, molecular structure, crystal type and crystallinity of banana starch and resistant starch are described. It is hoped that this review will provide a reference for the applications of spectrum analysis in the investigations of starch and resistant starch.
