Research Progress of Optical Nondestructive Testing Technology for Fruit Quality

Under the dual influence of the huge fruit yield and increased demand standard, it is urgent to find a convenient and efficient nondestructive testing method for fruit quality. The paper mainly introduces the application of four kinds of optical nondestructive testing technology in fruit quality testing, including the machine vision technology, the near infrared spectroscopy, Raman spectroscopy and hyperspectral imaging technology, and the research process and development status of optical nondestructive testing technology for fruit quality are summarized and sorted in this paper. At the same time, the future development direction is prospected, so as to provide basic theoretical reference for the research work of optical nondestructive testing for fruit quality.
