A Comparison of Fresh Pork Colour Measurements by Using Four Commercial Handheld Devices
The objective of this study was to evaluate the performance of different low-cost instruments to measure pork colour in comparison to Minolta spectrophotometers and industry subjective standards. Canadian pork colour standards and commercial meat (252 loin chops and 46 tenderloins) were measured usi...
