Extrusion‐based three‐dimensional (3D) printing has been extensively studied in the food manufacturing industry. This technology places particular emphasis on the rheological properties of the printing ink. Gel system is the most suitable ink system and benefits from the composition of plant raw materials and gel properties of multiple components;...

Cellulose nanocrystals (CNC) have gained widespread attention in intelligent food packaging because of their iridescent optical properties. Here, we report a CNC composite film employing CNC, sugar alcohols (e.g., maltol, erythritol, mannitol, sorbitol, xylitol, and anthocyanins), which has a special iridescent color that can be used as a pH and hu...

Cellulose nanocrystals (CNC) exhibit great potential as a food emulsifier or functional material template. Herein, CNC-Fe nanoparticles were successfully prepared via an in situ chemical reduction approach. Zeta potential measurements, low-field nuclear magnetic resonance spectroscopy, and atomic force microscopy showed that Fe(III) ions were adsor...

This study aimed to understand the impact of different oil types on the cellulose nanocrystals (CNCs) to modulate lipid digestion and the in vitro gastrointestinal toxicity of CNCs in food systems. We explored the ability of CNCs to modulate lipid digestion in a simulated gastrointestinal system and monitored the gastrointestinal fate of CNC-based...

Cellulose nanocrystals (CNCs) can self‐assemble in an aqueous solution to form a chiral nematic liquid crystal structure, which is maintained in the subsequent solid iridescent film and presents a unique structural color. In this study, in order to explore the effect of ultrasound on the optical properties of CNC, CNC films with a chiral nematic he...

A route for creating edible 3D materials is the use of highly concentrated oil-in-water emulsions. In this study, a high internal phase Pickering emulsion (HIPPE) was prepared by centrifuging pre-emulsions at different CNC concentrations. We found that HIPPE with an internal phase volume fraction of 80% can be obtained at 0.5 wt% CNC concentration...

This study investigates the interactions between cellulose nanocrystals (CNCs) and bovine serum albumin (BSA) under different pH conditions. A multiscale technique was employed to characterize the CNCs and BSA at pH 7 and pH 3. ζ-Potential measurement and UV–vis spectroscopy demonstrated strong interactions between CNCs and BSA at pH 3, whereat the...

This study was aimed to investigate the fabrication and properties of magnetic cellulose nanocrystal (MCNC) and further explored its application in stabilizing Pickering emulsions. The MCNC was successfully synthesized by ultrasound-coprecipitation. Combinational morphological and structural techniques were used for characterization. The results hi...

Cellulose nanocrystals (CNCs) were successfully produced with good nanoscales and dispersibility, using a recycled sulfuric acid (H2SO4) hydrolysis process. This method, at the cost of an overall 25% increase in the hydrolysis time, could significantly reduce the dosage of H2SO4 by approximately 40% without affecting the per-batch yield and perform...

BACKGROUND Sugarcane straw is an available but largely ignored lignocellulosic biomass to obtain cellulose nanocrystals (CNCs) with highly crystalline, tunable surface chemistries and a wide‐ranging adaptability. Herein, we utilized sugarcane straw to obtain pure cellulose via purification processes, followed by subsequent preparation of CNCs via s...

The synthesis of novel functional materials from abundant food waste resources has great application potentials and ecological benefits. Nanocellulose is a renewable and sustainable polymer that possesses a modifiable surface, excellent mechanical strength, and high aspect ratio, and it is non-toxic. These unique properties garner nanocellulose a p...

Understanding how patterns of recovery and geological conditions affect microbial communities is important for determining the stability of karst ecosystems. Here, we investigated the diversity and composition of microorganisms in karst and non-karst environments under natural restoration and artificial rehabilitation conditions. The results showed...

Soil enzymes play a vital role in biogeochemical cycling and ecosystem functions. In this study, we examined the response of six soil enzymes to changes in physicochemical properties resulting from changes in season and vegetation and geological conditions. Catalase, urease, acid phosphatase, invertase, amylase, and cellulase not only promote carbo...

Mining and smelting activities are the major sources of antimony (Sb) contamination. The soil around Xikuangshan (XKS), one of the largest Sb mines in the world, has been contaminated with high concentrations of Sb and other associated metals, and has attracted extensive scholarly attention. Phytoremediation is considered a promising method for rem...

[Objective] This paper aims to clarify the effects of different forests on soil microorganism and soil enzyme activity under different geological conditions, providing a theoretical basis for further research on restoration of natural ecological system. [Method] The soil samples were collected separately in rhizosphere of Eucalyptus robusta plantat...
