Abstract
Gomphrena globosa (globe amaranth) is an edible flower containing betacyanin pigments and bioactive compounds that contribute to sensory attributes such as purple coloration and floral aroma, yet its application in mocaf-based cookies has not been widely explored in terms of sensory profiling. This study aimed to describe the sensory profile and physicochemical characteristics of mocaf cookies substituted with globe amaranth powder at levels of 0%, 5%, 10%, 15%, and 20% using the Rate-All-That-Apply (RATA) method with 70 untrained panelists at the Sensory Evaluation Laboratory of Universitas Pembangunan Nasional “Veteran” Jawa Timur, where 22 sensory attributes were analyzed using the Kruskal–Wallis test and Principal Component Analysis (PCA). PCA revealed that F0 (100% mocaf) was associated with caramel aroma, sweet aroma, sweet taste, fatty taste, and yellow color; F1 (5% substitution) with savory taste, crunchy mouthfeel, light texture, gritty texture, and gritty mouthfeel; F2 and F4 (10% and 20% substitution) with dense texture, dry mouthfeel, bitter taste, burnt aroma, throat irritation mouthfeel, and floral aroma; and F3 (15% substitution) with floral taste, beany aroma, ashy aroma, brown color, roasted aroma, and purple color. Proximate analysis showed moisture content (2.69–3.68%), ash (0.54–1.89%), fat (11.23–17.20%), protein (4.36–5.31%), and carbohydrate (57.79–63.98%), indicating that substitution with globe amaranth powder influenced both the sensory attributes and chemical characteristics of mocaf cookies.
