Roselle is commonly used in pet food in the form of powder or extract, suitable for pet snacks (such as meat sticks, biscuits) and hypoallergenic dry food. It has a mild sweet and sour flavor and can enhance the palatability of the food while providing natural herbal support. It is suitable as a "flavor + function" dual-effect additive. Its bright color can also assist in improving the appearance of the product, balancing visual appeal and health attributes. It is particularly suitable for pet food that emphasizes taste and natural ingredients.
