Abstract:
This study aims to develop a dodol confectionery, incorporating bananas as a
substitute for sugar and rice flour. Three dodol formulations were prepared with
varying rice flour: seeni banana ratios (7.5:2.5, 5:5, 4:6) together with equal amounts
of other food additives (potassium sorbate and alfa tocopherol). Initially, the
ingredients were mixed and cooked at 80-90°C for 1hr. The best formulation (rice
flour: banana: coconut milk: sugar: potassium sorbate - 5: 5: 66: 24: 0.1) was selected
from a sensory evaluation with 30 untrained panelists. Proximate composition and
fatty acid profile, were analyzed in the final product. The keeping quality of the
product was also assessed based on free fatty acid value and microbial stability by
total plate count (TPC), Coliforms and yeast and mold count (YMC), over a 14-day
storage period. The developed banana incorporated dodol contained 22.55%
moisture, 2.30% protein, 8.10% fat, 58.20% carbohydrate, 0.50% ash and 0.20%
crude fiber. As per the fatty acid profile, the product has 7.71% saturated fatty acid
and not detected any trans fatty acid. The water activity and energy were determined
as 0.76 at 25°C, 315 kcal g-1 respectively. The pH (5.46±0.02), TSS (8.40±0.20) and
color L* (30.63±0.15), a* (9.47±0.11), b* (11.67±0.21) were recorded initially and
no significant changes were observed during storage. Consequently, with a free fatty
acid value below 2% and standard enumeration of TPC, YMC and coliforms were
also found at a safe level (<105 CFU g-1, <103 CFU g-1 and <3 MPN mL-1,
respectively) on the 14th day. In conclusion, there is a potential of utilizing banana as
a substitute for sugar and rice flour in developing dodol.
