Case Study

Ethyl Cellulose Used for the Preparation of Antibacterial Aerogels for Shelf Life Extension of Fresh Rice Noodles

Li, Haiyan, Zekun Jin, and Nengguo Tao. International Journal of Biological Macromolecules 307 (2025): 142138.

Ethyl cellulose (EC), a food-grade, hydrophobic polymer, was utilized in the fabrication of aerogels designed for the controlled release of (E)-2-hexenal-an antimicrobial essential oil-to preserve the quality of fresh rice noodles. In this study, EC was combined with agarose (AG) to form biopolymer-based aerogels capable of sustained antibacterial activity.
The EC/AG aerogels were prepared by dropwise addition of EC solution (0.08 g/mL in ethanol) to an AG aqueous solution (0.02 g/mL), followed by thermal mixing at 70 °C, ultra-low temperature pre-freezing at -80 °C, and vacuum freeze-drying at -110 °C for 48 hours. Varying EC concentrations (ratios of 1:10, 2:10, and 3:10 relative to AG) produced aerogels with distinct porosities and hydrophobic characteristics. Higher EC content resulted in more uniform pore structures, enhanced mechanical strength, and improved control over (E)-2-hexenal release profiles.
The optimized formulation (EC-AG-3) loaded with 0.20 μL/mL (E)-2-hexenal exhibited robust antimicrobial efficacy, suppressing spoilage bacteria for up to 72 hours and extending the shelf life of fresh rice noodles by four days at ambient temperature. Key quality indicators such as microbial load, pH, water activity, texture, and cooking properties were significantly preserved.
This case underscores ethyl cellulose's role as a structural and functional component in novel aerogel systems for active food packaging applications.

Ethyl Cellulose Used for the Preparation of CaCO₃ Nanoparticle Dispersions in Paper Deacidification Applications

Bračič, Matej, et al. Surfaces and Interfaces 60 (2025): 106065.

In this study, ethyl cellulose (EC) was utilized to prepare stable dispersions of calcium carbonate (CaCO₃) nanoparticles for non-aqueous deacidification of acidic paper. The experimental process began with dissolving EC in ethyl acetate at a concentration of 2 wt.%. Separately, dry CaCO₃ nanopowder was added to the EC solution at varying concentrations (0.25-1 wt.%) to form mixed systems labeled as EC+C(x), where x denotes CaCO₃ content.
To achieve uniform dispersion, the mixtures underwent probe ultrasonication at 750 W power, with a 30% amplitude and pulsed mode (5 s on, 5 s off) for 5 minutes. This treatment led to the formation of well-dispersed CaCO₃-EC nanoparticle suspensions, in which the EC acted as a stabilizing shell around agglomerated alkaline particles (250 nm in size), improving compatibility in the non-aqueous ethyl acetate medium.
For application, acidic model paper samples were treated via dip-coating in the CaCO₃-EC dispersions for 1 hour. Following immersion, samples were hung vertically and dried overnight at room temperature. Various control and experimental groups were labeled according to the presence or absence of EC and CaCO₃. This systematic approach enabled a precise evaluation of EC's role in particle stabilization, uniform penetration, and pH neutralization during the deacidification process.
The methodology demonstrates the practical utility of ethyl cellulose in forming effective non-aqueous nanoparticle delivery systems for paper conservation.

Ethyl Cellulose Used for the Preparation of Bio-Based Foams via Emulsion Templating Method

Cao, Huaqiang, et al. International Journal of Biological Macromolecules 306 (2025): 141502.

To address the growing issue of plastic pollution, this study presents a sustainable approach using ethyl cellulose (EC) for the preparation of fully bio-based foams through the emulsion templating method (ETM). Ethyl cellulose played a key role as a stabilizer in forming water-in-oil (W/O) Pickering emulsions, together with silicon dioxide (SiO₂) and acrylated epoxidized soybean oil (AESO).
The preparation process began by weighing the required amount of AESO, followed by sequential addition of 4 wt% EC and 0.6 wt% SiO₂. After thorough mixing, distilled water was added at an oil-to-water ratio of 6:4, and emulsification was performed at 25 °C by mechanical stirring at 200 rpm for 30 minutes under 20% relative humidity. Orthogonal experiments were conducted to optimize the curing parameters, with the optimal condition being 80 °C for 3 hours in the presence of 3% benzoyl peroxide (BPO).
To create the foam structure, 1.0 wt% ammonium bicarbonate (NH₄HCO₃) was used as a blowing agent and heated for 15 minutes. The resulting foams exhibited low density (0.176 ± 0.006 g/cm³) and excellent thermal insulation (0.065 ± 0.002 W/m·K). This work highlights ethyl cellulose's function in stabilizing Pickering emulsions and promoting porous foam formation, offering an eco-friendly alternative to conventional polymeric foams in packaging and insulation applications.
