The addition of corona to meat during the dry-aging process, designated by the abbreviation DP, refers to deliberately introducing controlled microbial growth on the surface of the meat. This surface growth, resembling a “crown” or “corona,” plays a significant role in flavor development and tenderization. For example, specific mold strains, carefully selected and cultivated, can contribute unique enzymatic activity to the meat’s exterior.
This controlled inoculation is important because it protects the meat from undesirable spoilage organisms. The microbial colony creates a microclimate on the surface, impacting moisture levels and enzymatic breakdown of proteins. Historically, this method was often unintentional, arising from environmental factors in traditional aging cellars. Modern applications allow for greater control, potentially resulting in enhanced flavor profiles and reduced risk of spoilage.
