Summary: An efficient technique using citric acid and glucose based natural deep eutectic solvent (G-C-NADES) was developed to obtain ultrahigh deamidated wheat gluten (UDWG) with a deamidation degree of up to 92.45%, 22% higher than traditional citric-acid-DWG method. The technique demonstrates enhanced accessible conformation of WG through HBs of G-C-NADES, contributing to the improvement on the nucleophilic attack of deamidation and potentially guaranteeing the safety of wheat gluten based cereal food in terms of lowering its allergenicity.

Summary: To effectively improve the antibacterial and physical properties of corn starch/chitosan films, starch/chitosan/polyethyleneimine (PEI) blend films crosslinked by citric acid were prepared. It was found that the addition of 3.75% PEI improved the tensile strength and elongation at break, but decreased the thermal stability. Incorporation of citric acid significantly enhanced the tensile strength and thermal stability of the films. Strong interactions were observed among citric acid, PEI, and starch-chitosan. All films showed inhibitory effects on E. coli and S. aureus, with the film containing 3.75% PEI and 5.0% citric acid having the best overall properties.

Summary: In this study, starch and empty fruit bunch-based bioplastic composites were modified with epoxidized palm oil (EPO) or citric acid-epoxidized palm oil (CEPO) oligomer using melt blending to improve mechanical properties and water resistance. The incorporation of CEPO led to stronger interactions with starch/fibers and changes in X-ray diffraction patterns, resulting in improved tensile strength and young's modulus. EPO decreased the melting temperature of the composites, while CEPO increased it due to crosslinking effects. The addition of both oils also slightly reduced water sensitivity and permeability of the composites.

Summary: The utilization of natural deep eutectic solvents (NADESs) for super-deamidation of wheat gluten is a cost-effective method to broaden its application as a plant protein source and reduce allergens. A ternary hydrated NADES composed of betaine, citric acid, and glucose achieves a record-breaking degree of super-deamidation at 99.58%. The interaction between betaine, citric acid, and glucose in the NADES during hydration plays a crucial role in the accessibility of the buried amide group.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
