The current gluten-free products generally have inferior taste, texture and nutritional value compared to their gluten-containing counterparts. Rosa-Sibakov et al (2016) evaluated the effects of processing faba bean flour on textural, structural and sensory properties of gluten-free pasta. Pasta was prepared using faba bean flour, starch-rich fraction of faba bean flour or faba bean flour fermented with lactic acid bacteria. The impact of cross-linking enzyme transglutaminase on the quality of faba pasta was also studied. The structure, cooking quality, starch digestibility (in vitro), textural and sensory characteristics of faba pasta samples were evaluated and compared to semolina pasta. Pasta prepared with faba bean and fermented faba bean flours had higher cooking loss and lower water absorption than semolina pasta but pasta prepared from fractionated faba flour had similar water absorption to semolina pasta. The texture of pasta made with faba bean flour was comparable to that of semolina pasta. Fermentation adversely affected the texture by increasing hardness, chewiness, sourness and flavour intensity. Starch hydrolysis index (in vitro) of pasta prepared with the three faba bean flours was similar to semolina pasta (46–50). Transglutaminase treatment reduced the (in vitro) starch hydrolysis index and increased some textural parameters of pasta made with faba bean flour, but no influence was observed on pasta made with fractionated or fermented faba. This study showed that faba bean flour and fractions can be used as an ultimate source of high protein gluten-free pasta with textural characteristics and starch hydrolysis index similar to traditional semolina pasta.
