Effects of ionic liquid 1-allyl-3-methylimidazolium chloride treatment on the microstructure and phase transition of cornstarch

Applications of ionic liquids in starch chemistry: a review

“…b) Water acts as a solubility enhancer, which disrupts glucose-glucose interactions and enhances glucose- 108 This suggests that specific starch chain breaking reactions occur depending on the cation present in the IL, which can be linked to the theory of Papanyan et al 95 Recently, a mixture of [Emim][OAc]:water (mole ratio 0.15:1) was reported to dissolve normal maize starch at 28 °C, 105 although in another study, waxy maize starch was not dissolved completely in aqueous [Amim][Cl] at 25 °C. 109 We must highlight that the mechanism of starch dissolved in aqueous ILs under ambient condition is different from the mechanism during heating due to the interaction between starch and water are negligible at ambient temperature. The dissolution behavior of maize starch in the mixtures of water and alkylmethylimidazolium chloride at ambient temperature (22-23 °C) was studied by Ren et al 110 At water:IL ratios of 10:1 and 5:1 (mol./mol.…”

Structural disorganization of cereal, tuber and bean starches in aqueous ionic liquid at room temperature: Role of starch granule surface structure

“…The dissolution behavior of starch (rate and degree of granule disintegration) in ILs-based solvents J o u r n a l P r e -p r o o f are affected by several factors, but not limited to the solvent effects only (Zhao, et al, 2015). Firstly, the type and structure of cations and anions of ILs can highly affect starch dissolution.…”

Toward a Better Understanding of Different Dissolution Behavior of Starches in Aqueous Ionic Liquids at Room Temperature

“…1,13,14 ILs have attracted considerable interest as solvents for polysaccharides, including cellulose, lignin, and starch, owing to their high ability to destroy the hydrogen bonds in these biopolymers. 13,15−17 Examples of IL solvents studied in this regard include 1-ethyl-3-methylimidazolium acetate, 1,18−20 1-allyl-3-methylimidazolium chloride, 13,19,20 and 1-butyl-3-methylimidazolium chloride. 21−23 The [Cl]-based ILs were used initially and are more widely applied than other types of ILs.…”
