Research progress of nondestructive testing techniques for fruit and vegetable quality

The quality of fruit and vegetable products is one of the important factors affecting market prices and customer satisfaction. Nondestructive testing techniques provide a rapid way to perform quality evaluation at a relatively low cost. Considering the rapid development of nondestructive testing techniques, some relevant literatures are reviewed in this paper. The principles, applications, characteristics and problems of near infrared spectroscopy technology, machine vision, hyperspectral imaging analysis, acoustic detection, electronic nose, dielectric properties analysis and nuclear magnetic resonance technology are briefly highlighted and summarized. Based on above the review, this paper discusses the solutions further and explores future opportunities and prospects to form the latest reference for researchers.
