Abstract

Indonesia is a country with rich biodiversity, including javanese turmeric (Curcuma xanthorrhiza Roxb.), which can be used as a food additive, such as in snack bars. The research aims to determine the optimal addition of javanese turmeric powder and baking duration for snack bars with the best antioxidant properties. The study employs a completely randomized design (CRD) with two factors: variations in javanese turmeric powder addition (1.5, 3, and 4.5 g) and baking duration (20, 25, and 30 minutes). The best treatment identified from the research is the addition of 3 g of javanese turmeric powder and a baking duration of 20 minutes, showing significant differences in texture, color, and overall preference. The color preference scores at 3.40, aroma at 3.20, taste at 3.16, texture at 3.48, and overall rating at 3.32. Chemical analysis of the selected snack bars resulted in a water content of 5.66%, protein content of 8.16%, and antioxidant activities measured by DPPH (1,1-Diphenyl-2-Pickrylhydrazyl) and FRAP (Ferric Reducing Antioxidant Power) at 60.92% and 10.48 mg E ferro/g, respectively. Additionally, the phenolic content was found to be 50.49 mg GAE/g. These findings indicate that snack bars with added javanese turmeric exhibit health-promoting antioxidant properties.

Abstract

Consumer preference for gluten-free products is increasing, which aligns with health awareness. Mocaf cookies with mucuna pruriens and pumpkin can be a new alternative for healthy snack innovation. This research aims to design and determine the optimal formulation of mocaf mucuna pruriens pumpkin cookies based on parameters affecting the process and favored by panelists. A Completely Randomized Design (CRD) Factorial method with two replications was applied, consisting of two factors. The first factor is the proportion of mucuna pruriens and pumpkin addition, which consists of six variations: 10:60 (F1), 20:50 (F2), 30:40 (F3), 40:30 (F4), 50:20 (F5), and 10:60 (F6). The second factor is the difference in drying temperature, namely 110 ℃ (T1) and 120 ℃ (T2). This method was conducted to evaluate the effect of adding mucuna pruriens and pumpkin on the qualitative characteristics of cookies, such as organoleptic tests. Sensory properties testing was performed using a hedonic test that included evaluations of taste, aroma, color, texture, aftertaste, and overall product. The preference test was applied to 27 trained panelists with a rating scale of 1 (strongly dislike) to 7 (strongly like) conducted in 2 replications. The data obtained were analyzed using Analysis of Variance (ANOVA) to determine the effect of treatments and further analyzed using the Duncan Multiple Range Test (DMRT) at a 5 % significance level. Mocaf cookies with the addition of 40 % mucuna pruriens and 30 % pumpkin at a drying temperature of 120 ℃ were selected as the best mocaf cookies formulation according to the panelists.
