Portable near infrared spectrum food modeling and quick detection integral method and system
2015
The invention discloses the portable near infrared spectrum food modeling of one kind and quick detection integral method and its system, secondary development is carried out to portable near infrared spectrometer under windows systems, food inspection calibration model is set up by the concentration reference value and near infrared spectrum data of the component index parameter of calibration set food samples, the component parameter of collection food samples to be measured is detected by calibration model again, the concentration of component detected value to be measured of unknown sample is obtained;It can be obtained by adjusting model parameter for the specific optimum detection calibration model for detecting food object.Integral system includes sample spectrum data acquisition module, sample spectrogram pretreatment module and model and set up and evaluation analysis module.The quick detection to food component can be achieved in the present invention, and can actively build model according to the data characteristicses for detecting object, determine optimized parameter, sets up best model, improves the accuracy of detection of model.
