英文摘要:

      Near-infrared spectroscopy (NIR) is a new analytical technique with the features of non-destructive, rapid and low cost, which can realize the qualitative and quantitative monitoring of pesticide residues in agricultural products especially in fruits and vegetables. Near-infrared spectroscopy will have broad prospects in the agricultural products security field because of the outstanding advantages of non-destructive testing characteristic. This paper summarized the basic principles and the characteristics of NIR, introduced the pretreatment technology of NIR such as the pre-concentration technologies and the quantitative calibration models and reviewed the application situations of the near infrared spectrum technology in the detection of pesticide residues in fruits and vegetables. With the continuous development and perfection of the near infrared spectrum technology and the relevant processing technology, the application of near infrared spectroscopy detection of pesticide residues in fruits and vegetables is being developed with a tendency of high sensitivity and accuracy, easy automation and on the spot operation.
