| This study analyzed the effect of the inclusion of legume-derived pro-teins, specifically pea and fava bean protein, with varying solubility levels on theexpansion of corn starch. Three different proteins exhibiting low, medium, orhighsolubilityweremixedwithcornstarchtoobtainblendscontaining15%,25%,and 35% (w/w) of the protein. Extrusion was performed on a twin-screw extruderat three different screw speeds (200, 400, and 600 rpm), a moisture content of16% (w.b.), and a die temperature of 140◦C. Obtained extrudates were analyzedfor their expansion, unit density, and hydration properties, namely, water solu-bility index (WSI) and water absorption index (WAI). Extrudates containing theprotein with the highest solubility showed different patterns than those that hadproteins with low or medium solubility. Expansion ratio (ER) increased from amaximum of 3.55±0.24 for pure corn starch up to 5.45±0.43 when incorporat-ing 35% of the protein with medium solubility but significantly decreased downto 1.24±0.08 when incorporating 35% of the most soluble protein. The influenceon the system parameters, as well as on the hydration properties, was also great-est for the blends containing the protein with the highest solubility. Even thoughsignificant Pearson correlations were observed between protein solubility andER (r=−0.579), unity density (r=0.614), WSI (r=−0.634), torque (r=−0.612),as well as specific mechanical energy (r=−0.451), further research is neededto evaluate if the solubility is indeed the reason for certain behaviors or if otherprotein characteristics are more critical for expansion. |
