Cockcomb oil is a special part of pigs, which is located in the chest of pigs, that is, near the heart. Comb oil is called comb oil because its shape and color are similar. In cooking, comb oil is usually used to make soup or cook some traditional foods because of its special flavor and taste. To know the specific location of comb oil, we must know the anatomical structure of pigs. The body structure of pigs can be divided into three parts: head, trunk and limbs. Cockcomb oil is located inside the trunk of pigs, especially between the sternum and the spine. This position is very close to the heart and lungs of pigs, which is one of the reasons why comb oil has a strong fragrance. Besides special taste and fragrance, comb oil also has certain nutritional value. Cockcomb oil is rich in fat and can provide a lot of energy for the body. In addition, comb oil also contains some fatty acids and vitamins beneficial to human body, such as vitamin A and vitamin E. However, because of the high fat content in comb oil, it is not suitable for excessive consumption.
