Abstract

Dahlia cookies are a food product generally made using wheat flour as the main ingredient and sugar as a flavor enhancer. Tempeh flour can be used as a substitute for wheat flour because it has a higher protein content, as well as containing essential amino acids and dietary fiber. Coffee grounds are coffee processing waste that still contains bioactive compounds and fiber so it has the potential to be used as an additional ingredient that can contribute to aroma and sensory characteristics. This study aims to determine the effect of tempeh flour substitution and the addition of coffee grounds on the protein, fiber, carbohydrate content, and organoleptic quality of dahlia cookies. This study used an experimental method with a factorial Completely Randomized Design (CRD), consisting of two factors: tempeh flour substitution (30%, 70%, 30%, 70%) and the addition of coffee grounds (6%, 6%, 12%, 12%). The parameters tested included protein content, fiber content, carbohydrate content, and organoleptic tests (color, aroma, taste, and texture). The data from the proximate content analysis were analyzed using ANOVA, while the organoleptic data were analyzed using the Kruskal-Wallis test.

Abstract

Pumpkin flour has the potential to be used as a substitute for wheat flour due to its high fiber and micronutrient content. This study aims to analyze the effect of pumpkin flour substitution on the physicochemical and sensory characteristics of almond crispy and to determine the best formulation. The study used a single-factor Completely Randomized Design with five substitution levels (0%, 30%, 40%, 50%, and 70%) and three replications. The parameters observed included moisture content, ash content, fiber content, and organoleptic tests (color, taste, aroma, and texture). Data were analyzed using ANOVA and the Kruskal–Wallis test . The results showed that pumpkin flour substitution significantly affected fiber content and sensory attributes, but did not significantly affect moisture and ash content. Increasing the proportion of pumpkin flour increased fiber content but tended to decrease panelists' preference level. Based on the effectiveness test, the formulation with 70% pumpkin flour substitution produced the best combination of chemical and sensory qualities, so it has the potential to be developed as a high-fiber functional food product.
