Spices and herbs are among the most commonly adulterated food types. This is because spices are widely used to process food. Spices not only enhance the flavor and taste of food, but they are also sources of numerous bioactive compounds that are significantly beneficial for health. The healing effects of spices are connected with their antimicrobial, anti-inflammatory and carminative properties. However, regular consumption of adulterated spices may cause fatal damage to our system because adulterants in most cases are unhealthy. For that reason, the appropriate analytical methods are necessary for quality assurance and to ensure the authenticity of spices. Spectroscopic methods are gaining interest as they are fast, require little or no sample preparation, and provide rich structural information. This review provides an overview of the application of NMR spectroscopy combined with chemometric analysis to determine the quality and adulteration of spices.
香料和草药是最常被掺假的食品类型之一。这是因为香料被广泛用于加工食品。香料不仅能增强食物的味道和口感，而且还是许多生物活性化合物的来源，这些化合物对健康有显著的益处。香料的治疗效果与其抗菌、抗炎和消气特性有关。然而，经常食用掺假的香料可能会对我们的系统造成致命的损害，因为大多数情况下，掺杂物是不健康的。出于这个原因，需要适当的分析方法来保证质量并确保香料的真实性。由于具有快速、需要很少或不需要样品制备以及提供丰富结构信息的特点，光谱方法越来越受到关注。本文综述了 NMR 光谱结合化学计量学分析在确定香料质量和掺假方面的应用。
