摘要
水果从结果到成熟再到腐败的过程中,其风味会不断发生变化,如何甄别品质优越的果品对于果农选种育种、建立优质品牌形象以及消费者获得良好消费体验十分重要。近年来,无损检测技术以其无损性、快速性在果品检测方面占据重要地位。目前常见的无损检测方法有X射线检测、近红外光谱法、高光谱成像技术、太赫兹光谱技术、机器视觉检测技术、声学特征检测、光学特征检测以及介电特性分析法等,而微波介电技术以其无损、快速、精确的优点在评估水果品质方面得到广泛研究。本文综述了基于介电特性测定果品品质的原理、基于介电特性的无损检测方法以及各技术的适用场景、优缺点,分析了无损检测的重要性以及微波介电技术未来的研究方向。
In the process of fruit from fruiting to ripening and then to spoilage,its flavor will change constantly.How to identify high-quality fruits is very important for fruit farmers to select seeds and breeding,establish highquality brand image and consumers to obtain good consumption experience.In recent years,non-destructive testing technology plays an important role in fruit detection because of its non-destructive and rapid performance.At present,the common non-destructive testing methods include X-ray testing,near-infrared spectroscopy,hyperspectral imaging technology,terahertz spectroscopy,machine vision testing technology,acoustic feature testing,optical feature testing and dielectric property analysis.Microwave dielectric technology has been widely studied in the evaluation of fruit quality because of its non-destructive,fast and accurate advantages.In this paper,the principle of measuring fruit quality based on dielectric properties,the non-destructive testing methods based on dielectric properties,and the applicable scenarios,advantages and disadvantages of each technology are summarized.The importance of nondestructive testing and the future research direction of microwave dielectric technology are analyzed.
