Legumes have been identified as a key element of food innovation and excellent candidates for ensuring sustainability in food systems. However, certain legumes, such as faba beans and legume by-products, such as pea pods, are currently mainly being used in animal feed rather than exploited and valued in human nutrition. In this study, the nutritional properties, anti-nutritional factors, and in vitro protein digestibility of pea pod flour and raw and thermally treated (80, 120, 150, and 180 °:C during 30 min) faba bean flours were investigated. For pea pod flours, the results showed a very interesting protein content (12.13%) and insoluble fibers (37.45%), as well as appreciable amounts of minerals, mainly calcium, potassium, magnesium, manganese, and iron. For faba bean flours, thermal treatment did not significantly affect the crude protein, ash, starch, and fat contents of the processed beans. Meanwhile, compared with raw faba bean flours, thermal treatment significantly decreased insoluble dietary fibers, anti-nutritional factors such as phytic acid, tannins, trypsin inhibitors, and alpha-galactosides and progressively improved the in vitro protein digestibility by 7,7%. In conclusion, faba bean and pea pod flours show significant potential as novel ingredients in the food industry. Their combination will enable the development of protein, fiber, and mineral-rich food products.
