Summary: This study investigates the designable diversity of ternary ChCl/Gly coordinated with various metal-salts and their effectiveness in lignocellulosic pretreatment. Different solvent properties and reaction characteristics were elucidated, showing that alkaline/acidic strengths and hydrogen-bonding forces play key roles in component fractionation. It was found that a strong alkaline ChCl/Gly-K2CO3 solvent achieved 72% delignification with significant holo-cellulose preservation, while Lewis acidic ChCl/Gly-FeCl3 (or AlCl3) removed a substantial amount of hemicellulose and lignin. Based on the lignin structural characterization, a potential reaction mechanism related to solvent properties was proposed to develop efficient ternary coordinated deep eutectic solvents.

Summary: Hydrothermal pretreatment is an effective method to improve the saccharification of lignocellulose. In this study, an efficient hydrothermal pretreatment of sunflower straw was conducted, resulting in the removal of 58.8% xylan and 33.5% lignin at a treatment temperature of 180 degrees C for 120 min and a solid-to-liquid ratio of 1:15. Various characterizations confirmed that hydrothermal pretreatment altered the surface structure and increased the accessibility to cellulase. The enzymatic saccharification of the treated sunflower straw achieved a high yield of reducing sugar and glucose and also produced xylo-oligosaccharide in the filtrate.

Summary: The aim of this study is to develop an environmentally friendly and effective method for the extraction of nutritious date sugar using natural deep eutectic solvents (NADES) and ultrasound-assisted extraction (USAE). The best performing NADES was synthesized using choline chloride (ChCl), citric acid (CA) and water in a ratio of 1:1:1 with 20 wt% water, resulting in a sugar yield of 78.30 ± 3.91 g/100 g. Further optimizations using response surface method (RSM) and artificial neural network (ANN) led to a sugar recovery of 87.81 ± 2.61 g/100 g. The NADES-USAE method showed a 43.1% higher sugar yield compared to conventional hot water extraction (CHWE). This study presents a promising approach for extracting nutritive sugars from dates using environmentally friendly solvents and advanced technology, while preserving the bioactive compounds.
