Yellow pith is a type of plant tissue found in the stems and branches of certain plants, particularly in the citrus family. It is located just beneath the outer skin and is often characterized by its light yellow color. This tissue plays a role in the plant's structure and can store nutrients. In citrus fruits, yellow pith is often associated with the bitter taste that some people experience when eating the fruit. While it is not harmful, many prefer to remove the pith to enhance the flavor of the fruit. Understanding yellow pith can help in preparing and enjoying citrus products.
