In order to minimize the deficiency of products with gluten-free and the growing number of celiac the elaboration of differential products using rice and maize flour becomes an alternative of consuming and marketing. This study aimed to evaluate the effects of rice and maize flour, and emulsifier addition in the quality characteristics (cooking test, instrumental texture - firmness and acceptability) and physic-chemical (proteins, lipids, carbohydrates, minerals and dietary fiber) of pasta formulation, by the use of experimental design methodology, fixing the concentration of in nature eggs (12%, w/w) and water (20%, v/w). The formulation with 40g of maize flour, 60g of rice flour and 0.4g per 100g of SSL mixed flour showed the better cooking resistance, reduced loss of solids in the cooking water (2.12% m/m), texture (30.40g sec-1) and acceptability higher than 85%. Furthermore, the use of rice flour associated with maize flour provide a source of minerals (152mg of K, 1.55mg of Fe, 46mg of Mg, 20mg Ca per 100g), proteins (~ 7%), carbohydrates (52%), fibers (~1%) important nutritional supplement for celiac, because they present significant losses of these nutrients due to restricted absortion and diarrhea, characteristic of the disease.
