Recently, the completion of the “Near Infrared Spectral Analysis Technology to Distinguish the Quality of Longkou Fans†project by the Quality Supervision Bureau of Longkou City, Shandong Province effectively filled up the gap in Longkou fans' identification technology and provided a “fire eye†for fans in Longkou. After years of efforts, the Bureau of Product Quality Supervision, Inspection and Inspection, jointly with the Food Quality Supervision, Inspection and Test Center (Jinan) of the Ministry of Agriculture and the Feed Research Institute of the Chinese Academy of Agricultural Sciences, jointly developed a set of near-infrared spectroscopy techniques for the identification of real and fake Longkou fans. Detection method. The project effectively combines optical instrument analysis technology, applied chemometrics technology, computer technology, statistical technology and other processing technology methods. Compared with traditional methods such as chemical detection and weighing, it has high technical content and high detection accuracy. High accuracy, fast test speed, no pollution in the measurement process and other obvious advantages. This technology can implement process control through on-line inspection during product production process, and can perform quantitative, qualitative detection or discrimination on products for sampling. It is the most technologically advanced technology method for implementing product quality supervision and quality control in the fan market. one. Near-infrared spectroscopy technology, as the earliest applied spectral analysis technology in the field of agriculture, has developed into an important method for grain quality analysis in countries such as Europe and the United States. Longkou fans use mung beans or peas as raw materials, and the composition formula is simple, making the near-infrared spectrum The analysis technology has a more natural advantage in the field of Longkou fan identification.
