Beetroot powder is the primary natural source of deep red and purple tones in pet food. It has strong coloring power and rich colors, making it suitable for products such as dry food granules, pet ham sausages, and functional wet food that require high-visibility colors. During processing, it is less affected by temperature and humidity, allowing the product color to remain stable for a long time. Even when mixed with meat ingredients, it is not prone to fading. When used as a pigment, it can either give the product a distinct red color alone or be combined with light-colored pigments to adjust the color scale, balancing both visual effect and the natural ingredient positioning.
