Description:	This study aimed to develop and assess the physicoche-mical, sensory parameters, and shelf life estimation of multicomponent snack bars based on tapioca flour, Brazil nut, and açaí or cupuassu pulp. The physicochemical composition of açaí- and cupuassu-flavored snack bars had, respectively, 0.92 and 0.99% ash, 19.22 and 17.02% lipids, 3.02 and 3.03% protein, 1.06 and 1.69% fiber, and 448 and 436 kcal/100 g energy value. The shear stress test showed the consumer needs to bite more strongly to break the açaí-flavored bar. The opposite was observed in the hardness test, in which the bite compression force during mastication was greater for the cupuassu-flavored bar. The bars had water activity below 0.6, which deno-tes microbiological stability. The sensory analysis ranked the bars between ?liked slightly? and ?liked very much,? which was confirmed by the acceptability index above 75% for all attributes assessed. According to the results a significant increase in water activity over storage was observed suggest the packaging used in the tests did not present a satisfactory barrier to water vapor permeability. Only water activity was used to estimate shelf life, which was determined as 58 days and 49 days for the açaí- and cupuassu-flavored bars, respectively. Thus, the snack bars represent an alternative for athletes as well as individuals with celiac disease since they are gluten free
