Embodiment

[0037] 1 Collection of pollutants to be measured

[0038]Commercially available commercial chickens were bled from the carotid artery and scalded at about 85°C. The abdominal cavity was opened to remove the intestinal tract and gallbladder, and the contents of the duodenum, ileum and cecum, the bile in the gallbladder, the blood collected during slaughter, and the soil were collected and placed in a truncated disposable paper cup (about 3cm deep) or In a glass Petri dish, spread evenly and seal with plastic wrap for later use.

[0039] 2 Preparation of chicken carcasses to be tested

[0040] Open the abdomen of the bloodletting and depilating chicken, remove the viscera, then rinse it with water, drain the water and hang it upside down on the iron rack of the slaughtering line. The collected pollutants were smeared with a diameter of 5 mm and a thickness of 1 mm. Among them, the contents of cecum, ileum, duodenum, and bile were smeared from the abdomen to the front chest in ...

Abstract

The invention relates to a detection method of pollutants on the surface of whole chicken rinses, belonging to the technical field of pollutant detection. Hyper-spectral images of the whole chicken rinses are collected at the key wave bands: 1070nm, 950nm, 870nm and 850nm, proportion treatment is carried out to the images, the produced proportion images display weather the pollutants exist or notafter being stretched. A multi-spectral imager and a detection model are arranged on a slaughter process, the whole chicken rinses which are detected with the pollutants re-enter in a washing link, and then the whole chicken rinses re-enter in a detection system. The detection results of the pollutants on the surface of whole chicken rinses, provided by the invention, utilizes a region of interest (ROI) to carry out matching, the detection ratio can reach more than 81.6602 percent, and the pollutants which are hard to see can be found, and an industrial application proposal of the detection system is provided. The detection method for the whole chicken rinses, applied to multiple spectrums, can reduce the working intensity of detection personnel, improves the detecting accuracy and is in accordance with HACCP scientific requirements.

Description

1. Technical field [0001] The invention relates to a method for detecting pollutants on the surface of chicken carcasses, which is specially used for the establishment of a hyperspectral image detection process for pollutants on the surface of chicken carcasses, and belongs to the technical field of pollutant detection. 2. Background technology [0002] There is no feast without chicken. Chicken is an important source of meat in people's lives, and meat safety has always been the focus of attention at home and abroad. Due to the strict epidemic prevention and quarantine procedures in the breeding process, the main reason for the unhygienic meat products is the slaughter of animals. In processes such as chicken slaughter and viscera removal, surface contamination of chicken carcasses often occurs. Common pollutants include visible pollutants, invisible pollutants and "hidden" pollutants. Visible pollutants such as the contents of the duodenum flowing out when the joint betwe...
