Pigs reveal secrets: New research shines light on Quebec industry

平特五不中 scientists develop technique to evaluate meat cuts by the light waves they emit

Which are the best pieces of pork, what their texture is, how moist they are 鈥 the secrets pigs keep from even the most skilled butchers 鈥 are about to be revealed, thanks to a sophisticated new technique that has been developed by 平特五不中 researchers in conjunction with Agriculture Canada and the pork industry. 鈥淭his is about giving industry workers better tools to do their job,鈥 explained Dr. Michael Ngadi of 平特五不中鈥檚 Department of Bioresource Engineering. 鈥淐omputer-aided analysis of meat will result in higher-quality jobs, optimal production, and exports that fit more closely with the target markets.鈥

The technology involves spectroscopy, a technique based on the analysis of the wavelengths of visible and invisible light produced by matter. By measuring the wavelengths of reflected light that pork cuts release, the researchers discovered they could easily determine the colour, texture and exudation (water release) of the meat. The technique is revolutionary, as previous laboratory techniques had involved destroying the testing sample. 鈥淭he technique enables production workers to conduct objective and scientific analysis of the meat very quickly on the production line,鈥 Dr. Ngadi said. It means the meat can be more accurately sorted according to the quality demanded by different export markets.

The research is not far from leaving the laboratory and entering factories, according to Dr. Ngadi. 鈥淲e are currently looking for partners who will work with us to build a ready-to-use device for a commercial production line,鈥 he said. The researchers are also looking to extend the technique for the evaluation of other aspects of meat quality, such as marbling and fat content.

This study was part of a project supported by funding from the Natural Science and Engineering Council of Canada and le Fonds qu茅b茅cois de la recherche sur la nature et les technologies.
