Adulteration monitoring of processed powdered horticultural products is an important aspect of research in order to facilitate fair trade, ensure food authenticity and safety in the agricultural food industries. Globally, a diversity of horticultural powdered products prone to adulteration include herbs and spices; fruit and vegetable flours; hot beverages and medicinal powdered products. This review article focuses on the utilisation of traditional and non-destructive technologies with emphasis on adulteration detection of powdered horticultural products. Nowadays, infrared spectroscopic technologies (visible to near infrared spectroscopy (Vis/NIRS), Fourier transform infrared (FT-IR), hyperspectral imaging and Raman spectroscopy) are preferred for processed product quality verification over conventional approaches (electrophoretic, gas and liquid chromatographic methods, enzyme-linked immunological assay (ELISA), polymerase chain reaction (PCR) and microscopic methods). Various applications of destructive and non-destructive techniques as well as their limitations in the field of powdered products adulteration detection have been extensively reviewed. A discussion on the concepts of adulteration, adulterants as well as the potential impact on health and agri-food industry is provided. The current status of destructive and rapid infrared methods as well as the future research direction for adulteration detection of powdered horticultural products is outlined. Chemometrics application towards developing excellent robust identification models from spectral data analysis to effectively assess the different adulteration levels of spices/herbs, hot beverage powders, fruit/vegetable flours and medicinal powdered products are illustrated.
加工粉状园艺产品的掺假监测是公平贸易、确保农业食品行业食品真实性和安全性研究的重要方面。在全球范围内，易发生掺假的粉状园艺产品包括草药和香料、水果和蔬菜粉、热饮和药用粉状产品。本文重点介绍了传统和非破坏性技术的应用，重点是粉状园艺产品的掺假检测。如今，与传统方法（电泳、气相和液相色谱法、酶联免疫测定（ELISA）、聚合酶链式反应（PCR）和显微镜方法）相比，红外光谱技术（可见近红外光谱（Vis/NIRS）、傅里叶变换红外（FT-IR）、高光谱成像和拉曼光谱）更适用于加工产品的质量验证。本文广泛回顾了破坏性和非破坏性技术的各种应用及其在粉状产品掺假检测领域的局限性。讨论了掺假的概念、掺杂物以及对健康和农业食品行业的潜在影响。概述了破坏性和快速红外方法的现状以及用于粉状园艺产品掺假检测的未来研究方向。本文还说明了化学计量学在开发出色的稳健识别模型方面的应用，从光谱数据分析到有效评估草药/香料、热饮粉、水果/蔬菜粉和药用粉状产品的不同掺假水平。
