Temperature responsive crosslinked starch-kraft lignin macromolecule

Recent advances in the fabrication, characterization and application of starch-based materials for active food packaging: hydrogels and aerogels

“…Previous research 81 has reported the preparation of hydrogels by crosslinking lignin sulfonate (KL) with starch. By analyzing the change in the C–O/C–O–C bond mass concentration (KLS, 55.5 ± 2.2%, KL, 37.2 ± 1.8% and starch, 42.3 ± 2.2%) using NMR and XPS, the changes in aromatic and anhydroglucose units of KL and starch were quantified.…”

“…Due to the clusteroluminescence properties of starch, a starch-based hydrogel is sensitive to moisture changes. 81 In the study conducted by Lai et al , 88 a responsive intelligent hydrogel packaging bag was developed using maize starch and was applied to the packaging of chicken breast meat. During the experimental process, the weight changes of the meat pieces were measured at regular time intervals under frozen conditions.…”
