Purple potato powder can provide a unique color range from deep purple to purple-gray. It is widely used in high-end pet food, pet pastries and snack freeze-dried products, helping to create a differentiated appearance for the products and attracting consumers who seek "novelty" and "high-end". Its color stability is strong, and the freeze-dried products do not easily change color during long-term storage. When combined with other natural pigments (such as pumpkin powder), it can also produce gradient colors, enriching the visual hierarchy of the products. As a pigment, its "purple potato component" label attribute can also enhance the credibility of high-end formulas.
