1. Natural pH-dependent coloring：Delivers vivid, gradient color changes from bright blue in neutral/alkaline conditions to soft purple and pink in acidic environments (e.g., when mixed with lemon, lime, or vinegar), providing unique visual appeal for food and beverage products without artificial colorants.
2. Natural antioxidant activity：Rich in anthocyanins (the primary bioactive compounds) and flavonoids, which exhibit natural antioxidant properties, helping to scavenge free radicals and support overall antioxidant balance in formulated products.
3. Subtle sensory enhancement：Adds a mild, fresh floral aroma and a delicate, earthy taste to formulations, complementing rather than overpowering the base flavor of beverages, desserts, and other food items.
4. Plant-based functional ingredient：Serves as a 100% natural, vegan, and gluten-free raw material, meeting the growing consumer demand for clean-label, plant-derived ingredients in food, beverage, and personal care products.
