Abstract

The invention discloses a method for rapidly detecting the amylose content in rice by near infrared spectrum and a visible light analyzer. The method comprises the following steps: S1: collecting rice samples; S2: determining the amylose content in rice by adopting a standard method; S3: collecting near infrared spectrum data of the samples by utilizing a near infrared spectroscopy; S4: pretreating the near infrared spectrum data; S5: correlating the near infrared spectrum data with an amylose value determined by the standard method, and establishing a near infrared calibration model; S6: carrying out external verification on the near infrared calibration model; S7: correlating the amylose value determined by the standard method with a color value determined by a visible light analyzer by utilizing a predicted value obtained by the near infrared calibration model, and establishing a comprehensive calibration model; and S8: carrying out external verification on the comprehensive verifying model. The method provided by the invention has the advantages of high analyzing speed, high efficiency, low cost, no pollution to the environment and the like, and the method can provide reliable basis for the rice quality analysis and rice quality control.

Description

technical field

[0001] The invention designs a method for quickly detecting the amylose content in rice by using a near-infrared spectrum and a visible light analyzer. Background technique

[0002] 90% of the world's total rice production is used for direct human consumption, and what is directly related to consumers is the edible and nutritional quality of rice. As amylose affects the taste, expansion rate and water absorption rate of rice, the color, luster, viscosity and hardness of rice determine the quality of rice. The amylose content is usually determined by colorimetry, and it takes at least several hours to measure a sample, which is not suitable for measuring the amylose content of large batches of rice. Therefore, it is necessary to find a method for quickly and accurately detecting the amylose content in rice, so as to provide a reliable basis for the quality analysis and quality control of rice.

[0003] In recent years, near-infrared spectroscopy has been wid...
