Method for authenticating Xiangshui rice by near-infrared spectroscopy

Abstract

The invention belongs to near infrared spectrum analysis and in particular discloses a method for authenticating Xiangshui rice by near-infrared spectroscopy. The method comprises the following steps of: building a clustering discrimination and eligibility discrimination model by respectively selecting a proper spectra preprocessing way, smooth points, a spectral interval, factor number and the like; and scanning a near infrared spectrogram of an unknown sample under the same condition, pre-processing the near infrared spectrogram, and authenticating the unknown sample according to the built clustering discrimination and eligibility discrimination model by selecting the same smooth points, spectral interval, factor number and the like. The method solves the problem of unavailable protection and authentication for the Xiangshui rice, the geographical indication product in the prior art, and has the advantages of well authenticating the Xiangshui rice, along with high identification rate.

Description

Technical field The invention belongs to near-infrared spectrum detection and analysis, in particular to a method for identifying Xiangshui rice with near-infrared spectrum technology. Background technique Geographical indication products refer to products produced in a specific region, whose quality, reputation or other characteristics are essentially determined by the natural and human factors of the place of origin, and which are named after the review and approval by the geographical name. Since the Chinese government issued the first notice on the approval of geographical indication product protection in 2000, hundreds of geographical indication protection products have been approved, involving more than 20 types. These products are produced in specific regions, or produced through special processes, and have undergone special quality control to have special quality and characteristics, and thus have high economic value. Among them, rice that has been protected by geog...
