Abstract

Nutrition-rich extruded snacks were developed from a mixture of cornflour, Bengal gram flour fortified by tree bean (TB) powder (0, 5, and 10%) using a twin-screw extruder. The nutritional, antioxidant, and amino acid profile and structural, functional, and sensory properties of the ready-to-eat (RTE) extruded snacks were evaluated. Ash, protein, and fiber content in TB-fortified extrudates were increased, whereas nitrogen-free extract was decreased. Total phenolics (2.34 mg g–1 FW), ascorbate (2.23 mg g–1 FW), total flavonoids (0.16 mg g–1 FW), and reduced glutathione (8.53 µM g–1 FW) were higher in the extrudates with 10% TB powder. Similarly, RTE extruded snacks fortified by 10% TB exhibited higher DPPH, FRAP, ABTS, hydroxyl radical activities, reducing power, and essential amino acids, such as lysine, leucine, isoleucine, cysteine, threonine, tyrosine, and methionine derived by HPLC. Extrudates fortified by 5% TB powder exhibited better microstructure through scanning electron microscopy. However, 10% TB powder possessed higher physicochemical properties and overall sensory attributes. This study reveals the tremendous industrial potential of nutrient-rich RTE extruded snacks fortified by underutilized TB (10%).
