Online batched salmon flesh volatility salt base nitrogen detection device and method based on spectral analysis

Abstract

The invention discloses an online batched salmon flesh volatility salt base nitrogen detection device and method based on the spectral analysis. The detection device comprises a detection conveying belt used for continuously conveying salmon flesh, a spectrum probe erected above the detection conveying belt and used for collecting spectrum information of the salmon flesh, a host used for receiving the spectrum information from the spectrum probe and conducting comparison on the spectrum information and the preset value so as to obtain a detection result, and a sorting mechanical arm used for sorting the salmon flesh on the detection conveying belt so as to distinguish qualified products and disqualified products according to the detection result. By means of the online batched salmon flesh volatility salt base nitrogen detection device and method based on the spectral analysis, large-batch automation detection of the salmon flesh volatility salt base nitrogen can be achieved, the feature wavelength of the salmon flesh volatility salt base nitrogen can be reflected to the maximum degree through the analysis, the illumination intensity corresponding to a wavelength optical filter is collected, the volatility salt base nitrogen calculation formula is determined through a multivariate linear regression method, spectrum data collection is reduced, a calculation model is simplified, and the purpose of rapid detection is achieved.

Description

technical field [0001] The invention relates to a spectrum detection technology, in particular to a device and method for quickly detecting salmon meat in batches online. Background technique [0002] In recent years, with the improvement of living standards, meat products are favored by people. Among them, salmon meat is especially popular among meat products because of its high protein and low fat advantages. However, with the increase in demand, the quality of salmon meat has received more and more attention and attention. [0003] At present, most of the detection methods around the world stay in chemical methods. This method brings higher detection accuracy, but at the same time, it is accompanied by the disadvantages of high cost, difficult operation, long detection cycle and damage to the quality of detection samples. The non-destructive testing technology of meat products has become a research hotspot, and spectral technology has become the most potential non-dest...

AI Technical Summary

Problems solved by technology

However, the spectral detection is mostly in the laboratory stage, requiring the operator to have very professional spectral knowledge, and there are many full-spectrum data, and the analysis is slow. The device and method for online large-scale and rapid detection of volatile base nitrogen in salmon meat have not yet been reported.
