From Yield to Flavor: The Role of Lipid Coatings in Beef Aging
ABSTRACT Lipid‐coated aging has been proposed as an alternative to enhance flavor, particularly using butter as a coating material (butter‐aged beef). Thus, this study compared the wet‐aged and beef‐aged with different lipid‐based coatings: milk butter (butter‐aged), cocoa butter (cocoa‐aged), pork lard (lard‐aged), and beef tallow (tallow‐aged), all ...
