This study investigates the sensory evaluation of brewed

products derived from Blue Pea (Clitoria ternatea L.) flowers

combined with Peppermint (Mentha sp.). Multiple Attribute

Decision Making (MADM) methods, specifically Rank Order

Centroid (ROC) and Simple Additive Weighting (SAW), were

employed for this purpose. The brewed samples were

prepared by boiling either the Blue Pea (Clitoria ternatea L.)

flowers alone or a mixture of Blue Pea flowers and

Peppermint, with varying amounts of added sugar. The

organoleptic scores of four formulations was assessed by a

panel of 30 untrained judges using a 9-point hedonic scale,

focusing on taste, aroma, and color criteria. Data analysis

began with ROC to determine the weights of each criterion,

followed by SAW to identify the optimal formulation. The

results indicated that the formulation consisting of 100 g of

Blue Pea flowers and 200 g of sugar achieved the highest

preference score of 0.9959.
