Abstract

The invention discloses a food modeling and rapid detecting integration method and system adopting portable NIRS (near infrared spectroscopy). According to the method, the portable NIRS is secondarily developed under the windows system, a food detecting and calibrating model is established according to concentration reference values of component index parameters of a calibration set food sample as well as NIRS data, component parameters of a to-be-detected set sample food are detected by the calibrating model, and concentration detection values of to-be-detected components of unknown samples are obtained; an optimal detecting and calibrating model aiming at specific detected food objects can be obtained by adjusting model parameters. The integration system comprises a sample spectrum data collecting module, a sample spectrogram pre-processing module and a model establishment and evaluation analysis module. With the adoption of the method and the system, food components can be rapidly detected, according to the data characteristics of detected objects, the model can be established initiatively, the optimal parameters can be determined, the optimal model can be established, and accordingly, the detection precision of the model is improved.

Description

technical field

[0001] The invention relates to food detection and data processing, in particular to a near-infrared spectrum food modeling and rapid detection integrated method and integrated system based on a small portable near-infrared spectrometer for secondary development under the windows system. Background technique

[0002] Existing detection technologies for food mainly rely on chemical analysis. Chemical analysis methods have disadvantages such as being greatly affected by human factors, large errors, long analysis time, cumbersome steps, and environmental pollution. With the progress of society and the rapid development of science and technology, as well as the needs of food companies and regulatory departments for timely supervision and control of food quality and safety, the on-site detection technology for food is developing towards the direction of rapid technology testing, and thus using spectral analysis software The technology of food detection and analysi...
