Abstract
Introduction In retail markets, color stability without discoloration is an economically important trait because it can allow for extended retail sale opportunities, fewer discounts, and reduced product loss. Ground beef is the most commonly consumed beef product in the United States. Historically, the source of ground beef comes from lower quality cuts, trimmings from subprimals, and subprimals from cull cows; however, alternative grinds from whole and/or premium quality subprimals are becoming more popular with consumers. Subprimals from the chuck and round are logical subprimals that could be used for premium ground beef production because they cost less than other subprimals such as those from the rib and loin. Ground beef products from higher quality grades such as Premium Choice (upper two-thirds of Choice) offer merchandising potential and are commonly utilized as a higher quality product. The inherent lean and fat property differences that may exist in these subprimals could potentially influence the color display stability of the resulting ground beef products.

Summary
Color stability without discoloration is an economically important trait because it can allow for extended retail sale opportunities, fewer discounts, and reduced product loss. The source of ground beef comes from lower quality cuts, trimmings from subprimals, and subprimals from cull cows; alternative grinds from whole and/or premium quality subprimals are becoming more popular with consumers. Ground beef products from higher quality grades such as Premium Choice (upper two-thirds of Choice) offer merchandising potential and are commonly utilized as a higher quality product. The inherent lean and fat property differences that may exist in these subprimals could potentially influence the color display stability of the resulting ground beef products. Extended vacuum storage before grinding could affect biochemical, oxidative, and microbial properties of these subprimals and influence their color stability. Our objective was to determine the effects of two subprimal types (chuck roll and knuckle), two quality grades (Premium Choice and Select), and three vacuum-packaged storage aging times before processing (7, 21, and 42 days) on ground beef patty display color stability
