摘要
some characteristics of the cassava depend on the variety used for the processing. the objectified of this study was to evaluate physicochemical characteristics of the cassava flour from varieties used in acre. the treatments were composed by the varieties: t1 = paxiubˋo, t2 = im221, t3 = caboquinha, t4 = araˋ芍, t5 = colonial, t6 = branquinha, t7 = panati and t8 = mansa e brava. samples of flour of eight cassava varieties were collect in cassava mils in cruzeiro do sul. the samples were sent by airmail to rio branco, acre, to be analyzed in the food and technology laboratory at embrapa-ac. the evaluated parameters were: water percentage, ashes, lipids, protein, fiber, carbohydrates, acidity, ph and water activity. all samples were taken according to the established patterns of the brazilian legislation for cassava flour, considering water percentage, ashes and carbohydrates. the analyzed flours presented low fibers levels and low acidity. the water activity of the analyzed flours was below the minimum limit necessary to allow microorganisms development. the varieties araˋ芍, colonial and branquinha were adequate to cassava flour manufacturing, mainly because of the high protein and carbohydrates levels present in the produced flour.
