PROCESSING PROCESS FOR PURPLE COFFEE RICH IN ANTHOCYANINS

Abstract

The invention relates to a process for producing anthocyanin-rich purple coffee by blending coffee with plant-derived ingredients, specifically an anthocyanin-rich extract from purple sweet potatoes, to create a product with a natural purple color, high antioxidant properties, and health benefits for consumers. The combination of the characteristic coffee flavor and natural purple color creates a novel, unique, and special natural food (beverage) product that enhances nutritional value and is suitable for industrial production, increasing the value of both coffee beans and purple sweet potatoes.
