A study by the Hanwoo Management Committee and Kongju National University found that Hanwoo (Korean native beef) raw meat is most tender and flavorful within 24 hours after slaughter. In this pre-rigor stage, muscle proteins bind strongly to water, producing a springy, juicy texture and reducing juice loss when cooked. Levels of flavor compounds inosine monophosphate (IMP) and glutamic acid are highest in this window, enhancing umami. The meat also shows a deep purplish-red color that later lightens with oxidation. Microbial counts were lowest within 24 hours because contracted muscles limit air contact, improving hygienic safety. The researchers say this short timeframe scientifically confirms the freshness and quality of Hanwoo and supports safe enjoyment of traditional raw preparations like yukhoe (육회) and yuk sashimi (육사시미).
