Quick detection method for aflatoxin B1 of rice based on near infrared spectroscopy

The invention belongs to the field of food quality detection and in particular relates to a quick detection method for aflatoxin B1 of rice based on a near infrared spectroscopy. The quick detection method comprises collection of a rice sample material, spectral acquisition, measurement of aflatoxin B1 of the rice sample, spectral pretreatment, construction of a correction model, checking of the model and measurement of the aflatoxin B1 content of an unknown rice sample. The method disclosed by invention aims at basic research and discussion on quick and nondestructive detection of harmful substances of the rice and is used for detecting the aflatoxin B1 content of the rice based on the near infrared spectroscopy. The method has the advantages of simpleness, feasibility, high analysis speed, high detection precision, low analysis cost and the like and the advantages that the sample is not required to be pretreated and the environment cannot be polluted; a reliable basis can be supplied to control of the storage quality of the rice and the quality of a rice processed product.
