To improve the use of common buckwheat (Fagopyrum esculentum), characterized by interesting nutritional properties, it could be used in pasta formulations. In particular, as buckwheat is devoid of the gluten-forming proteins, it might be an ingredient for celiac patient food. The aim of this study was to develop both fresh egg pastas integrated with buckwheat and fresh egg pasta analogues classifiable as gluten-free, based on buckwheat and rice flours. Matter loss in the cooking water and weight increase during cooking of buckwheat pasta were higher than those of a reference sample made of common wheat flour. As buckwheat integration increased, sample break strain was significantly lower, as a result of the progressive reduction in gluten content. In the production of gluten-free pasta analogues, wheat flour was substituted with rice flour, precooked rice flour or pregelatinized rice starch. Since samples containing precooked rice flour gave the best results, in terms of workability, break strain and weight increase during cooking, they were also produced on an industrial scale. Industrial gluten-free fresh egg pasta analogues were tougher and less deformable in comparison with the laboratory-produced samples. These results were determined by the presence of the double thermal pasteurisation treatment, which allows to obtain a better structure of the product, showing also a lower matter loss during cooking.
