A two-step heating process, long low temperature-short high temperature cooking cycle, is used to maximize fat reduction in roast beef. First, the beef was cooked at a low temperature for a long time; then, it was cooked at a higher temperature for a short time. The study examines cooking loss, fat content, texture, and inosine 5’-monophosphate (IMP) production of cooked meat under different heating conditions. In an oven, the internal temperature of the meat increased to a transition point of 48 or 54°C at oven temperatures of 80 or 100°C and reached 60°C at 220°C. The fat was reduced by up to 44.2% compared to 27.8% under conventional roasting conditions. In addition, the two-step heating process kept the meat tender and juicy but improved IMP content.
