Potato and sweet potato are two among the most important commodities worldwide due to their significant role in human diet and food security. As highly demanded crops, rapid quality monitoring methods prior to marketing, processing, and other post-harvest activities are the major concerns of consumers and food processors. The non-destructive techniques in terms of imaging and spectroscopy have become effective analytical tools in evaluating the quality of various horticultural and food products including potatoes and sweet potatoes. Hence, this paper reports the current knowledge on the recent applications of imaging and spectroscopy for inspecting the quality and safety of raw potato and sweet potato tubers. In this comprehensive review, the conventional quality evaluation (internal and external) are discussed, followed by description of imaging and spectroscopy as non-destructive techniques and, the summary of the recent successful implementations of these tools in relation to quality evaluation. The basic and fundamental components of the technique, measurement methods and data analysis applied, advantages, and challenges are also critically reviewed.

马铃薯和甘薯由于其在人类饮食和粮食安全中的重要作用，是世界上最重要的两种商品。作为需求量很大的作物，在销售，加工和其他收获后活动之前进行快速质量监控是消费者和食品加工者的主要问题。成像和光谱学方面的非破坏性技术已成为评估各种园艺和食品（包括马铃薯和红薯）质量的有效分析工具。因此，本文报道了有关成像和光谱学在检查生马铃薯和甘薯块茎质量和安全性方面的最新应用的最新知识。在这次全面审查中，讨论了常规质量评估（内部和外部），其次，将成像和光谱学描述为非破坏性技术，并简要介绍这些工具与质量评估相关的最新成功实施。还严格审查了该技术的基本和基本组成部分，所应用的测量方法和数据分析，优势和挑战。
