60,000 mu equivalent raw material cultivation base × international certification. A natural anthocyanin coloring agent derived from purple sweet potatoes, featuring stable coloration and high coloring power. Ideal for beverages, confections, and dairy products.
This product is a natural coloring agent derived from purple sweet potatoes (Ipomoea batatas) that contains anthocyanins. As a plant-based and food-compatible natural pigment, it can consistently impart vibrant shades ranging from bright red-purple to deep purple. With high coloring power, it contributes to the value enhancement of clean label products and organic products that aim to replace artificial colorants. Our company has a cultivation base of approximately 60,000 mu (equivalent to a large-scale land area) through our own and contracted farming, and we ensure a stable supply of purple sweet potatoes with high anthocyanin content from the raw material stage by thoroughly managing variety selection, soil management, and contamination-free cultivation. Manufacturing is conducted under hygiene management equivalent to GMP standards, and by optimizing the extraction and purification processes, we have achieved products with enhanced heat resistance, light resistance, and pH resistance. We offer the product in both powder and liquid forms, allowing for selection based on application. Due to its high solubility and excellent compatibility with acidic beverages, it can be used in a wide range of applications including soft drinks, functional drinks, yogurt, jelly, gummies, confectionery, ice cream, and bakery products. Under quality control that complies with international product safety standards, it has been widely adopted in OEM/ODM projects by beverage manufacturers, confectionery manufacturers, and dairy product manufacturers.
