Extended data:
Meat and bone soup is nutritious and delicious, mainly because protein and fat are dissolved in the soup. When stewing meat and bone soup, first put it in the pot with cold water, gradually raise the temperature and boil it, and then simmer it with slow fire. This can loosen the bone tissue of meat and bone, and gradually depolymerize and dissolve protein and fat in bone. As a result, the meat and bone soup is more simmering and thicker, oily as cream and chewy.
If water is added in the middle of stewing, the temperature of meat and bone soup will suddenly change, which will lead to the rapid solidification of protein and fat, which will shrink into a ball and no longer disaggregate. In this way, the gap on the surface of bone will be narrowed, leading to the contraction of bone tissue, which is not easy to burn brittle, and the protein and fat in bone marrow can not be dissolved in large quantities. At this time, the protein fat in the soup will be reduced accordingly, thus affecting the delicacy of the soup.
