Physicochemical and sensory characteristics of snack bars added of jerivá flour (Syagrus romanzoffiana)

Abstract

The objective of this work was to characterize promising fruit crops and to explore opportunities for the sustainable and commercial use of flours obtained from fruits as an ingredient in snack bars. The fruit selected was Jeriva, which grow from north to eastern Brazil, and can be found in the Savanna biome. The fruit flour was obtained from dehydrated pulps and the proximate composition, dietary fiber, vitamin C, % scavenging free radicals, mineral composition, pH, ºBrix, titratable acidity and sensory analysis were determined. The flour was incorporated into the formulation by partial substitution of the standard ingredients of snack bars. The presence of increasing amounts (up to 20%) of Jeriva fruit flour resulted in sensory accepted snack bars, with 7.02 average in the scores evaluated, without significant differences among the formulations and significantly increased the protein at 7.12%, vitamin C 40.81 mg.g-1 and fiber contentes showed values at 6.66% for dietary fiber. Moreover, the results of free radical scavenging confirmed the greater antioxidant activity proportional to the increment of flour. Therefore, Jeriva fruit flour could be an alternative sensorily acceptable, for obtaining of snack bars.
