Case Study

Sodium Decanoate Used for the Preparation of High-Performance Egg White Protein-Based Foaming Systems

Li, Xingyu, et al. Food Hydrocolloids (2025): 112166.

This study investigates the multifunctional role of sodium decanoate (SD) in enhancing the enzymatic hydrolysis and foaming properties of egg white protein (EWP), addressing the industrial challenge of thermal aggregation during enzyme inactivation. SD, a medium-chain fatty acid salt with amphiphilic properties, was incorporated into EWP solutions prior to enzymatic hydrolysis. Its amphiphilic structure induced partial unfolding of protein molecules, exposing additional enzymatic cleavage sites and nearly doubling the degree of hydrolysis.
Critically, during enzyme inactivation at 90 °C, SD effectively prevented thermal aggregation through steric hindrance and hydrophobic shielding, preserving solution clarity and fluidity. The hydrolyzed peptides in the presence of SD (SEW system) demonstrated significantly improved foaming performance, achieving 118.3 % foaming capacity and 69.9 % foaming stability. This enhancement was attributed to the formation of a thicker, more viscoelastic interfacial film at the air-water interface, which stabilized foam bubbles during processing.
Application testing in bread making confirmed the practical benefits of SD: loaves prepared with the SEW system exhibited the largest specific volume and an optimized soft-yet-resilient texture, demonstrating both improved aeration and mechanical stability.
Overall, sodium decanoate serves as a multifunctional additive for the preparation of high-performance protein-based foaming systems. Its combined effects of facilitating enzymatic hydrolysis, preventing thermal aggregation, and strengthening interfacial films provide a versatile strategy for developing EWP-based ingredients with enhanced processing stability and functional properties, offering significant potential for industrial food applications.

Sodium Decanoate Used for the Preparation of Corrosion-Resistant Coatings on Aluminium Alloy 2024

Boisier, Grégory, Nicolas Portail, and Nadine Pébère. Electrochimica acta 55.21 (2010): 6182-6189.

This study investigates the application of sodium decanoate (SD) as an effective corrosion inhibitor for aluminium alloy AA2024. SD, a long-chain carboxylate, functions by forming a hydrophobic protective layer on the metal surface, preventing chloride ion penetration and mitigating galvanic interactions between intermetallic particles and the surrounding aluminium matrix.
Electrochemical techniques, including bulk and local electrochemical impedance spectroscopy, were employed to elucidate the inhibition mechanism under varying conditions of pH (4-10) and NaCl concentrations. The results indicated that SD adsorption significantly enhanced the resistance of the passive oxide layer, as evidenced by high contact angles and increased impedance values. Local impedance mapping on an Al/Cu model system demonstrated uniform adsorption of SD over both aluminium and copper surfaces, effectively limiting galvanic coupling-a primary driver of localized corrosion in AA2024.
The protective effect of SD was observed across a wide pH range, highlighting its robustness for diverse environmental exposures. By forming a continuous, hydrophobic film, SD not only prevents chloride-induced breakdown of the oxide layer but also passivates intermetallic sites, thereby reducing the overall corrosion rate.
These findings establish sodium decanoate as a multifunctional additive for the preparation of corrosion-resistant coatings on aluminium alloys. Its ability to combine hydrophobic barrier formation with galvanic coupling mitigation underscores its potential for industrial applications in surface treatment and long-term protection of AA2024 in chloride-containing environments.

Sodium Decanoate Used for the Enhancement of Intestinal Barrier and Antioxidant Functions in Porcine and Murine Models

Zhao, J., Hu, J., & Ma, X. (2021). Nutrients, 13(8), 2756.

This study investigates the application of sodium decanoate (SD) in improving intestinal barrier integrity and antioxidant defense in both IPEC-J2 cells and C57/BL6 mice models. SD, a medium-chain fatty acid salt, was evaluated for its ability to mitigate oxidative stress induced by H2O2 and to enhance gut physiological functions.
In vitro experiments revealed that SD at 1 mmol/L upregulated tight junction protein expression in IPEC-J2 cells, effectively reinforcing cellular barrier function. Additionally, SD improved the antioxidant capacity of cells under oxidative stress conditions, as indicated by enhanced scavenging activity and reduced oxidative damage. Comparative analysis with sodium butyrate confirmed the superior efficacy of SD in these protective roles.
In vivo, SD administration significantly increased ileal villus height, improved intestinal morphology, and enhanced growth performance of mice. Moreover, SD modulated gut microbiota by increasing α-diversity and promoting the production of volatile fatty acids. Mechanistic investigations indicated that these benefits were mediated via activation of the G protein-coupled receptor-43 (GPR-43) signaling pathway in the ileum and colon, linking SD supplementation to improved intestinal barrier and metabolic signaling.
Overall, this work establishes sodium decanoate as a multifunctional agent for enhancing intestinal health, promoting growth, and mitigating oxidative stress. Its dual action-strengthening the epithelial barrier and activating GPR-43-mediated antioxidant pathways-highlights its potential application in animal nutrition and functional food development.
