Ultra-optical spectrum image-forming system and testing methods of meat product tenderness nondestructive testing

Abstract

The invention discloses an ultra-spectral imaging system and a detection method for the nondestructive detection of meat tenderness, which pertains to the technical field of nondestructive detection of foods. The ultra-spectral imaging system includes an image collection device which consists of an infrared CCD digital camera, an ultra-spectral spectrograph and a second lens, the ultra-spectral spectrograph, a light source supply system, a computer and so on. The detection method is that the whole system is arranged in a closed light shielding compartment, so as to prevent the external light interference. The image collection device collects the ultra-spectral image data, the computer uses an original image processing method and the mathematical algorithms to extract the image characteristics from the ultra-spectral image and establish a mathematical model, and the invention uses a cross return validation method to further establish a forecast evaluation model to be measured. The invention can obtain the measurement performances and rules of the ultraspectral imaging system for the different meat by the analysis of the characteristics of the ultraspectral images of the meat to be measured, the invention can realize the internal quality and safety evaluation of the meat products which can not achieved by the pervious artificial methods in a non-contact mode, which is rapid, convenient and safe.

Description

technical field [0001] The invention belongs to the technical field of non-destructive detection of food, and in particular relates to a hyperspectral imaging system and a detection method for non-destructive detection of tenderness of meat products. Background technique [0002] Meat is an important food in people's diet. With the end of my country's shortage economy and its entry into WTO, its quality and safety are increasingly valued. Problems such as the imperfect management system and the lack of efficient and rapid detection methods have become increasingly prominent. Especially in recent years, the wide application of pesticides, veterinary drugs, feeds, feed additives, animal and plant hormones, etc., while promoting a substantial increase in the output of agricultural and livestock products, has also brought hidden dangers to the quality and safety of agricultural and livestock products. In addition, industrial waste and municipal solid waste pollute the agricult...

Problems solved by technology

However, due to the inability to effectively detect and grasp the quality and safety situation in China, the problem is detected by the other party when it arrives at the port of the trading country. However, when foreign meat products enter my country, many toxic and harmful substances cannot be detected, and technical barriers cannot be effectively implemented to protect my country's food safety
