Many people add a little vinegar when making bone broth. Why is that? If adding vinegar to bone broth is beneficial, when is the best time to add it?
The benefits of adding vinegar to bone broth
Many people believe that drinking bone broth can supplement calcium. In fact, bone broth can only supplement calcium when a little vinegar is added; otherwise, the calcium content in bone broth is minimal. Adding a little vinegar to bone broth can convert inorganic calcium into calcium acetate, which dissolves out, increasing the calcium ion content in the broth and making it more nutritious. Additionally, adding vinegar to bone broth can also enhance its flavor and stimulate the appetite.
When is the best time to add vinegar to bone broth?
Adding an appropriate amount of vinegar during the boiling process of the bone broth can maximize the dissolution of calcium from the bones, increasing the calcium content in the broth.
Furthermore, the amount of vinegar should not be increased indiscriminately during the cooking process, as it will affect the taste of the bone broth. Extending the cooking time of the bone broth will slightly increase the calcium ion content in the soup. This is because bones have a porous nature, and the diffusion of soluble substances from the numerous small pores and the reaction of acetic acid with inorganic calcium salts in the pores before dissolving into the broth both require time. Therefore, as the time is extended, the calcium ion content in the broth will continue to increase, but after a certain period (23 minutes), the increase is not significant. Hence, the cooking time cannot be extended indefinitely.
