Celiac individuals require a gluten free diet, which includes products such as rice pasta. However, this cereal has lower protein content, when compared with other cereals, and poor cooking and texture technological characteristics for pasta. The aim of this research was the development of rice pasta with high protein content through a Central and Rotational Composite Design with three independent variables, as follows: [X.sub.1]--isolated soy protein (ISP--0-20%); [X.sub.2]--modified and dehydrated egg albumin (ALB--0-15%); and [X.sub.3]--pre-gelatinized rice flour (GRF --0-30%). The pasta samples were analyzed for cooking time (CT), solid loss in cooking water (SL), weight gain (WG), firmness and adhesiveness. It was verified that ISP, ALB and GRF significantly influenced (P < 0.10) CT, SL and firmness, with values between 300 and 525s, 2.22 and 9.84% and 4.82 and 11.13N, respectively The optimum point was obtained with the addition of 17% ISP, 15% ALB and 15% GRF, indicating a product with excellent cooking and texture properties to include in the diet of celiacs. Key words: celiac disease, rice flour, soy protein, albumin, gluten free pasta. Individuos celiacos necessitam de dieta sem gluten como, por exemplo, massas alimenticias de arroz. No entanto, esse cereal apresenta o menor teor de proteinas, em relacao aos demais cereais, e deficiencia em caracteristicas tecnologicas de cozimento e textura para as massas alimenticias. O objetivo deste trabalho foi desenvolver massa de farinha de arroz com alto teor de proteina atraves de Delineamento Composto Central Rotacional de tres variaveis independentes, sendo: [X.sub.1]--isolado proteico de soja (IPS--0-20%); [X.sub.2]--albumina de ovo modificada e desidratada (ALB--0-15%); e [X.sub.3]--farinha de arroz pre-gelatinizada (FAG--0-30%). As massas foram analisadas quanto a tempo de cozimento (TC), perda de solidos na agua de cozimento (PS), aumento de peso (AP), firmeza e adesividade. Verificou-se que a adicao de IPS, ALB e FAG influenciou significativamente (P < 0,10) no TC, PS e firmeza, com valores entre 300 e 525s, 2,22 e 9,84% e 4,82 e 11,13N, respectivamente. O ponto otimo foi obtido com adicao de 17% de IPS, 15% de ALB e 15% de FAG, indicando um produto com excelentes caracteristicas de cozimento e textura para inclusao na dieta de celiacos.
