The better barrel bone should be the leg bone of the hind leg, because the bone here is thicker. Tubular bone is nutritious in all parts of the bone, which not only contains some protein, iron, calcium, phosphorus and vitamins, but also various trace elements necessary for human body. Moreover, the bone marrow in bones contains collagen, which can not only promote wound healing, but also enhance physical fitness.

shopping tips

1, smell if there is any strange smell, because fresh meat doesn't smell bad, just a little meaty.

2, look at the color, if the bone is a little white and bloodless, it is not fresh.

The hand feels sticky and stale.

4. Choose a pig bone with two big ends and a small middle, and the sides are not flat, so there is no bone marrow, and then be careful not to choose too much meat.
