英文摘要:

      As a new detection method, non-destructive testing (NDT) technology has great differences with the traditional detection technology. The technology is widely used in food analysis because it can accomplish the detection tasks without destroying the sample and it has been paid more and more attention of researchers. In this paper, based on the different detection mechanisms, several kinds of non-destructive detection techniques including optical methods, acoustics and mechanics methods, X-ray method, electrical methods, electromagnetic methods and sensor methods were introduced, which were widely used in quality appraisal of fresh food. This paper summarized the applications of these methods in the identification of fresh food quality and compared the characteristics of these techniques. Due to the diversification of these techniques, it was needed to select different detection techniques to obtain the best test results according to the different detection objects and objectives. With the development of science and technology, the non-destructive testing technology will be more simple, miniature, portable, specific and highly sensitive.
