    Apr 26, 2002· Pre-rigor/Hot Boning of Pork Carcasses. April 26, 2002. Lynn Knipe. Associate Professor. The Ohio State University. The fresh, “bloom” color of meat is enhanced with rapid chilling (using CO 2) of pre-rigor meat, as soon after hot boning as possible. This improvement in color can be reflected in a sharper particle definition (less smeared look), as well as a leaner appearance.
