System and method for detecting quality of livestock meat

Abstract

The invention discloses a system for detecting quality parameters of livestock meat, which comprises a light source system emitting point light sources for irradiating a sample to be detected, an imaging spectrometer connected with an optical condenser thereon and used for acquiring a scattered spectrum image on the surface of the sample to be detected, a CCD camera connected with the imaging spectrometer and used for converting an acquired spectrum image optical signal into a digital electric signal, a data acquisition system connected with the CCD camera and used for acquiring the digital electric signal converted by the CCD, and a control computer connected with the data acquisition system and used for receiving and processing the digital electric signal transmitted by the data acquisition system. The invention also relates to a method for detecting the quality parameters of the livestock meat, which comprises the following steps of: imaging acquiring, imaging correcting, imaging fitting, optimal wavelength acquiring, and sample quality parameters detecting. The system and the method are people oriented and have advanced skill, rapid and pollution-free detection processes, evaluation of beef quality in a nondestructive and non-contact way, and the potential for real-time on-line detection application.

Description

Technical field [0001] The invention belongs to the field of quality detection of agricultural and livestock products and is used for quality detection of livestock meat. It relates to a spectroscopic non-destructive rapid detection system and detection method for meat quality. More specifically, it relates to the collection and characteristics of hyperspectral scattering images on beef surface Methods of extraction and quality parameter detection. Background technique [0002] Beef is fresh, tender, delicious and nutritious, and it is a kind of low-cholesterol meat that people love. Since the reform and opening up, with the development of the economy, the improvement of people’s living standards and changes in consumption concepts, the demand for beef has increased year by year. In 2005, my country’s total beef production reached 7.225 million tons, accounting for 11.25% of the world’s total beef production. The world's third largest beef producer. In the international market, ...
