国家的最先进的药品，营养保健品，营养品和红外应用

---

红外光谱，包括近红外(NIR)和中红外(MIR)，是绿色、快速和环保技术的一个例子。它被认为是一种新颖的、快速的有机化合物“指纹”分析方法。

在过去的几十年里，这一技术的应用开辟了在分析科学和技术的新方向。它的联合使用导致的质量控制和质量保证，安全性和可追溯性的新方法，以及在他们的总体分析创新，建立模型系统应对挑战的化学计量学。

本期特刊旨在综述利用ATR和传输模式进行中、近红外光谱研究的最新进展。特别关注的是新药、膳食补充剂、植物制剂和营养品的设计和开发应用，以及生产和质量保证过程的开发和标签的潜在用途。

所有的文章，这是这个特别问题的一部分，反映了现代趋势和概述了在食品和制药部门结合化学计量数据分析光谱技术的未来应用的新想法。

该特刊包含三个评论文章和三个普通纸。M. Zhu等人的论文。评论近红外（NIR）反射光谱和化学计量学茶的质量控制。茶是世界上最流行的饮料之一。各种各样的茶叶品质，但是，要求对商业化的茶叶产品质量的控制措施。NIR反射光谱是一种快速，非侵入性，和无损的工具，需要最少的样品制备。文章给出了最近在这一领域的进步和应用的概述。由C.埃尔南德斯-咀等人的综述。地址photoacustic光谱（PAS）的应用程序，以评估食物的质量。该PAS技术是基于光热的现象，这让光谱研究。 An overview is given on PAS applications in the food industry, for example, to analyse fruit, vegetables, condiments, grains, milk, water, eggs, and so on. It was concluded that the method is capable of detecting adulteration and contamination of food samples. The third review article by S.A. Mahesar et al. is concerned with the applications of NIR and MIR spectroscopic techniques to olive oils. A special focus of the paper is the detection and determination of functional compounds such as fatty acids and phenols. It is demonstrated that MIR spectroscopy is particularly well suited to distinguish olive oils from potential adulterants.The contributed regular papers demonstrate cutting-edge advancements of the field. G. Shi et al. described real-time release testing of herbal extract powder by near-infrared spectroscopy considering the uncertainty around specification limits. For two active pharmaceutical ingredients (APIs), they show that the reliable concentration ranges covering the specification limits can be verified by the accuracy profile (AP) methodology. The method was tested in the estimation of the β-content and γ-confidence tolerance intervals (β‐CTIs) around the specification limits. H. Ouhaddouch et al. applied FT‐IR spectroscopy for the identification of a mineral drug substance in drug products using a case study on bentonite. For this purpose, they carefully characterized purified bentonite, bentonite in organic mixtures and organic excipients, and mineralized organic mixtures containing bentonite. They observed distinct changes and variations in the spectra, which could be attributed to the properties of the samples. H. Fu et al. reported the use of an NIR-MIR data fusion technique and evaluated the spectra via a moving window partial least-squares discriminant analysis for authenticity and adulteration discrimination of herbs. They concluded that their approach is a promising tool for the rapid discrimination of geoherbalism and authenticity of Chinese herbs. We hope that the readers will find this special issue interesting and inspiring.
