Abstract

Cascara is a herbal beverage product derived from processed coffee skin waste. However, the acidic odor of cascara is not favored by consumers. To improve the quality of cascara, is to combine them with red ginger (Zingiber officinale var. Rubrum). Red ginger contains volatile components such as zingiberene and zingiberol, which provide a distinctive fresh aroma that can mask the sour odor of cascara. The purpose of this study was to determine the effect of different ratios of cascara and red ginger on the physical, chemical, organoleptic, and microbiological quality of tea bags containing cascara with added red ginger, in order to obtain the best formulation. This research was conducted using a randomized complete block design (RCBD) with four treatment ratios: T0 (100% cascara: 0% red ginger), T1 (90% cascara: 10% red ginger), T2 (80% cascara: 20% red ginger), T3 (70% cascara: 30% red ginger), and T4 (60% cascara: 40% red ginger). The different ratios of cascara and red ginger significantly influenced the physical, chemical, organoleptic, and microbiological properties of the tea bags containing cascara with added red ginger. The best formulation was obtained from treatment T3 (70% cascara: 30% red ginger), which had a color preference rating of 4.15, an aroma preference rating of 4.34, a taste preference rating of 4.17, an L* value of 32.377, a pH value of 5.05, a moisture content of 13.461%, a total phenol content of 21.105 mg GAE/g, an antioxidant activity of 68.115%, and a total microbe count of 3.36 × 103 CFU/ml.

Abstract

Extensive research has been conducted to investigate the formulation of a new generation of cereal-based Gluten Free (GF) foods formulated with High-Resistant Starch (RS) sources and high in nutritional value. Black glutinous rice flour is a rich in bioactive compound and MOCAF is known for its high RS content often used as an alternative to wheat flour in the production of gluten-free cookies. The formulation of the combination of these two ingredients needs to be investigated to produce gluten free cookies that have good physical and sensory characteristics. The aims of these research was to investigate the effect of different ratio of Black Glutinous Rice Flour (BGRF) and MOCAF (MF) formulation (F1 = 100:0, F2= 75:25, F3=50:50, F4= 25:75, F5= 0:100) on physical and sensory parameter of resultant GF cookies. The results shows that, cookies with high amount of BGRF showed interesting physical properties with higher diameter, spread ratio, and ∆E of the cookies, lower weight, thickness, baking loss, L*, a*, b*, C* value, and the hedonic score of color, aroma, taste, texture, overall compared to cookies with 100% MF. The best formula that produces gluten free cookies with the highest taste score score is F4 (BGRF 25%:MF 75%) with physical characteristics weight 10.70 g, diameter 48.40 mm, thickness 8.60 mm, spread ratio 5.63, baking loss 17.37 %, L* 53.96, a* 0.63, b* 17.65, C* 17.66, ∆E 48.78. With the combination of BGRF and MF on cookies dough, we manage to obtain cookies that has great potential to increase the nutritional quality of gluten-free food.
