Beef quality multi-parameter simultaneous detection method by multichannel near-infrared spectroscopy

Abstract

The invention discloses a beef quality multi-parameter simultaneous detection method by multichannel near-infrared spectroscopy, belonging to the rapid nondestructive detection range of beef quality. The method comprises the following steps: first, arranging a spectral detection system comprising an 8-channel fiber multiplexer, two spectrometers with different wavelength ranges and probe units ina movable control cabinet, wherein the 8-channel fiber multiplexer is respectively connected with the spectrometers and the probe units; embedding in a production line technology to carry out on-linedetection to obtain optimum spectra data, wherein the quality detection of carcass and cut meat can be simultaneously satisfied; establishing a calibration prediction model, evaluating model effects by using relative analytical errors, carrying out model analysis on a large number of sample experimental data, respectively establishing prediction models of tenderness and water content to obtain a predicted value of each index, and then plugging the obtained predicted values into a beef multi-parameter comprehensive quality evaluation model which is established based on the detected indexes to obtain a final meat grade. According to the invention, the spectral information in the visible near-infrared band is collected, the information is abundant, the detection indexes have extensibility, and the method can be suitable for the requirement of production line detection.

Description

technical field

[0001] The invention belongs to the scope of rapid and non-destructive detection of beef quality, in particular to a multi-channel near-infrared spectrum multi-parameter simultaneous detection method of beef quality. Background technique

[0002] Beef grading refers to dividing beef products into different grades according to the market's recognition of beef quality, so as to realize the benefit distribution of high quality and high price. The widespread promotion of beef grading plays an important role in the healthy development of the beef industry. It can guide beef producers to conduct qualitative breeding, scientific feeding, and standardized slaughtering and segmentation, so that they can produce beef products with high quality and high price; Regulate the beef market to form a benign and healthy market competition; it can also guide consumers to consume correctly and ensure the fairness of transactions.
