Use infrared technology for high-speed meat inspection.A variety of techniques have been examined for determining the endpoint temperature in meat. These include a time-temperature indicator that is based on changes in color produced by the chemical reaction between reducing sugars and amino acids. But this method is restricted to a limited group of products. Another approach involves examining the protein concentration of cooked turkey and chicken. Now scientists at the University of Arkansas The University of Arkansas strives to be known as a "nationally competitive, student-centered research university serving Arkansas and the world." The school recently completed its "Campaign for the 21st Century," in which the university raised more than $1 billion for the school, used (Department of Food Science, 272 Young Ave., Fayetteville, AR 72704) are employing infrared (IR) technology to do the task. They found that IR can be coupled with time series analysis and a laser range system to estimate the internal temperature of meat, as well as to identify the coldest and hottest spots inside the product. This approach has significant potential for the online inspection of endpoint temperatures of chicken products. The core of the system is a focal planar array In telecommunications and radar, a planar array is an antenna in which all of the elements, both active and parasitic, are in one plane.[1][2] A planar array with a reflecing screen is related to a Radar absorber. (FPA 1. (hardware) FPA - floating-point accelerator. 2. (programming) FPA - Function Point Analysis. ) IR camera. The FPA makes possible a noncontact temperature measurement with a resolution of 0.1 C. The camera generates a high-resolution image in which every pixel is an accurate noncontact thermometer thermometer, instrument for measuring temperature. Galileo and Sanctorius devised thermometers consisting essentially of a bulb with a tubular projection, the open end of which was immersed in a liquid. . The camera registers thermograms (images) at a rate of 60 frames/sec. This makes it possible to perform an inspection without reducing processing speed See MHz. . In addition, the spectral band of the camera practically avoids any interference with close-to-oven conditions, such as steam and humidity. In experiments, the external temperature in just-cooked chicken was registered with an IR camera, and the corresponding internal temperature was measured with thermocouples. The system was able to estimate internal temperature with a standard error of approximately 1 C. Researchers intend to find the best FPA IR camera for the task, achieve fast three-dimensional information in close-to-oven conditions, determine the coldest spots in the meat according to according to prep. 1.
