The invention discloses a portable system NIR (near infrared spectrum) rapid food detection and modeling integration system and method. The system comprises a small-sized near-infrared spectrograph, an android smart phone and a driving module; and a Y-type USB cable is used for connection. According to the system, the smart phone is utilized to perform secondary software development on a small-sized NIR instrument so as to realize sample pretreatment analysis of a collected sample, establish a calibration model and perform detection analysis; the near-infrared spectrograph is small in size, light in weight and easy to carry; scanning and analyzing speed is fast; and a quantitative analysis can be conducted. By utilizing the technical scheme provided by the invention, a user cannot be restricted by a solidification model in supporting analysis software provided by an instrument; in practical detection, an appropriate model can be actively constructed according to the data characteristics of a detection object, and an optimal parameter is found and determined to establish an optimal model and improve the detection accuracy of the model. By the system and the method disclosed by the invention, the nondestructive detection analysis of flour can be realized.

Description

technical field [0001] The invention belongs to the technical field of rapid food detection, and relates to a portable near-infrared spectrum detection technology based on an android development platform, in particular to a rapid detection and detection of near-infrared spectrum food for secondary development of near-infrared spectrum equipment Modeling integrated method and its integrated system. Background technique [0002] The commonly used food testing methods at this stage mainly include chromatography, mass spectrometry and spectral analysis. Chromatography, although fast and widely used, is destructive to samples. The disadvantages of mass spectrometry are insufficient resolution, high price, and high maintenance costs. The spectroscopic analysis method has almost no damage to the sample and the experimental environment, and the detection speed is fast. With the rapid development of the economy, people are paying more and more attention to food safety. Embedded T...
