Abstract: This study focuses on the development of a functional beverage combining blueberry juice with Clitoria ternatea (blue pea flower). The research evaluates its acceptability, shelf life, nutritional composition, and sensory characteristics. The blue pea flower, known for its high anthocyanin content and health benefits, was incorporated into blueberry juice at different concentrations to determine the most suitable formulation. Sensory parameters such as appearance, color, texture, flavor, and taste were analyzed by a semi-trained panel. Additionally, nutrient profiling, microbial stability assessment, and cost analysis were conducted to ensure the product's affordability and stability. The results indicate that the formulated Blue Pea Butterfly Drink is a nutritious and cost-effective functional beverage with potent antioxidant properties, making it a promising addition to the market. Sensory evaluation identified Sample D as the most preferred formulation in terms of overall acceptability.
