Leroyet al. [31] used 1-butyl-3-methylimidazoliumchloride ([BMIM]Cl) as plasticizer
for starch–zein (main protein in corn) blend, comparing their results to glycerol
plasticizer. The presence of [BMIM]Cl allowed to obtain a lower water uptake and
better thermodynamical behaviour than samples with glycerol, resulting in an improved
blend compatibility.
