I occasionally see comments such as ‘the target needs to be heated to 70°C to be properly killed’. This is only half the story. As with all cooking, a target may need to be heated to 70°C to be properly cooked, but it must be maintained at that temperature for a certain amount of time… Continue reading Tissue denaturation temperatures and times – how are they related?
