Barras de amaranto enriquecidas com frutanos: aceitabilidade e valor nutricional

there is an increasing appeal for convenience foods with potential health benefits to the consumer. raw materials with high nutritional value and functional properties must be used on the development of these food products. amaranth is a gluten-free grain with high nutrition value. inulin and oligofructose are prebiotic ingredients presenting effects as the enhancement of calcium absorption. amaranth bars enriched with inulin and oligofructose were developed in the flavors: banana, brazilian nuts and dried grape, coconut, peach, strawberry and wall nut. the proximate composition were determined and compared to commercial cereal bars, available in traditional (n=59), light (n=60), diet (n=8), with soy (n=10) and quinoa (n=1) categories. amaranth bars present mean global acceptance values from 6.3 to 7.6 on a 9-point hedonic scale, nutritional advantages as compared to commercial cereal bars (caloric reduction and higher levels of dietary fiber). although amaranth is an unknown raw material in brazil, it shows good potential to be used in the manufacturing of ready-to-eat products. as they are gluten free, these amaranth bars are also an alternative product for celiacs, also contributing to the enhancement of calcium absorption, a problem frequently observed in these patients.
