The aim of this work is to study new, extruded products based on corn flour enriched with carob bean and the evaluation of its functional quality to develop novel gluten-free food products. Five samples based on corn flour with added carob bean flour (5 to 12.5%) were formulated. Extrusion was performed using a single-screw laboratory extruder at pilot plant scale. Extrusion parameters such as color and carbohydrate content (fiber, sucrose, and starch) were evaluated. Carob bean addition led to an increase in starch, soluble fiber, and insoluble fiber. Texture parameters related to hardness (crunchiness) were significantly reduced with the addition of CB (p 5%) no major differences in color were observed. The extrusion process reduced the content of soluble and insoluble fiber, and sucrose in all formulated samples. Extruded samples with 5–7.5% CB seem to be the best formulation in terms of fiber content, color, and texture parameters. These innovative gluten-free foods could be considered as a source of fiber, and a healthier alternative to some commercially available snacks.
