Shi, Xueying, et al. Food Hydrocolloids 163 (2025): 111111.
In this study, erythritol was employed to induce the formation of β-glucan-based microgels derived from Dictyophora rubrovalvata (DRP), aiming to develop a gelatin-free gelling system for low-calorie gummy applications. The extraction of DRP began with ethanol pretreatment of dried fruiting body powder, followed by hot water extraction at 75 °C, ethanol precipitation, deproteination, dialysis, centrifugation, and lyophilization to obtain purified polysaccharides.
For gel preparation, DRP was dissolved in deionized water at a concentration of 3% (w/w) and stirred at room temperature for 24 h. Subsequently, erythritol was added at varying concentrations (0-9%, w/w), and the mixtures were stirred at 1500 rpm for 5 min. The suspensions were then subjected to thermal treatment at 90 °C for 30 min, followed by static incubation at 25 °C for 2 h to allow gelation. The resulting samples were designated EDM-0 through EDM-9 according to erythritol content.
Among them, EDM-5 (5% erythritol) formed a stable, resilient microgel with enhanced water retention and structural integrity. Characterization via FTIR, XRD, SEM, and molecular docking confirmed the formation of new hydrogen bonds and a strengthened gel network. This thermally induced gelation process highlights erythritol's critical role as a structuring agent in DRP-based gels suitable for functional food development.

This study demonstrates the efficient transformation of erythritol into 1,3-butadiene via catalytic hydrodeoxygenation (HDO) under liquid-phase batch conditions. Using rhenium (Re)- and molybdenum (Mo)-based metal oxide catalysts supported on carbon black (CB), researchers investigated erythritol's selective C-O bond cleavage under hydrogen-rich atmospheres (60 bar H₂, 140 °C). The one-step HDO reaction proceeds through a key intermediate, 3-butene-1,2-diol, which appears at short reaction times and subsequently converts to the target olefin.
Catalyst screening revealed that Re-enriched systems (20 wt%) exhibit improved erythritol conversion (65%) and 1,3-butadiene selectivity (88%), compared to lower Re loadings (2-5 wt%). Notably, a bimetallic 5Mo-10Re/CB catalyst displayed optimal performance with 93% 1,3-butadiene selectivity at 51% erythritol conversion after 5 hours. The combination of Mo and Re promotes both redox and acidic functionalities, favoring C-O scission while suppressing over-hydrogenation to butenes.
X-ray photoelectron spectroscopy (XPS) and CH₃OH-TPSR analyses confirmed the coexistence of fully and partially reduced Mo and Re species, responsible for the catalytic activity. The regeneration of spent catalysts by N₂ treatment showed no loss in activity or selectivity, underscoring catalyst durability.
This work presents a viable strategy for converting erythritol, a biobased polyol, into high-value platform chemicals such as 1,3-butadiene under mild conditions, offering sustainable prospects for bio-based chemical synthesis.

This study presents a novel application of erythritol (Ery) in the preparation of inclusion complexes with hydroxypropyl-β-cyclodextrin (HP-β-CD) for use in active food packaging. The HP-β-CD/Ery complex was synthesized via an ultrasound-assisted method, wherein equimolar amounts (5 mmol) of erythritol and HP-β-CD were dissolved in 40 mL of purified water and subjected to ultrasonic treatment (65 W, 1 s pulse, 2 h). The resulting white solid was obtained by freeze-drying.
These inclusion complexes were further incorporated into a nanofiber matrix composed of polylactic acid (PLA), gelatin (Gel), glycerol (GI), and metal-organic framework ZIF-8 using electrospinning. The addition of HP-β-CD/Ery and ZIF-8 increased fiber diameters from 337.36 nm to 2184.20 nm, enhanced thermal stability and hydrophilicity, and reduced crystallinity. Notably, the fiber membranes exhibited controlled and sustained release of erythritol over 240 h, effectively delaying the microbial degradation of grapes.
Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) confirmed successful complex formation, while the functional film showed significant antimicrobial and antioxidant activities. This work highlights erythritol's multifunctional potential beyond sweetening, offering a biocompatible, biodegradable, and effective solution for next-generation food packaging systems with prolonged preservation capabilities.
