Innovative Coating Technology Enhances Food Safety in Galvanized Steel Storage

March 2024

Galvanized steel containers have long been a staple in the agricultural industry for storing harvested produce, owing to their durability, strength, and cost-effectiveness when compared to stainless steel alternatives. However, the presence of bacteria within these containers poses a significant challenge, as it can lead to corrosion and potential contamination of stored food items. Addressing this concern, a team of researchers led by Dr. Mustafa Akbulut from the Department of Chemical Engineering and Dr. Luis Cisneros-Zevallos from the Department of Horticultural Science at Texas A&M University has developed a groundbreaking two-step coating solution for galvanized steel, promising safer food storage and enhanced food safety measures.

The newly developed coating boasts a range of benefits aimed at mitigating corrosion and bacterial adherence while maintaining the structural and mechanical integrity of the steel. Notably, the coating has been shown to reduce corrosion by a remarkable 70%, offering a significant improvement in the longevity of storage containers. Furthermore, its bacterial-repelling properties prevent harmful microbes from adhering to the surface, thereby reducing the risk of contamination.

In addition to its corrosion resistance and anti-bacterial properties, the coating has demonstrated efficacy in reducing bacterial strains over a seven-day period and minimizing adherence to foodborne fungi such as Aspergillus. Moreover, it effectively minimizes contamination from mud, further bolstering food safety measures.

The potential applications of this innovative coating technology extend beyond food storage containers to include agricultural equipment, such as silos, thereby offering a comprehensive solution for enhancing food safety throughout the agricultural supply chain.

The impact of this breakthrough technology on the agricultural industry and consumer confidence in food safety cannot be understated. By improving the safety and integrity of stored produce, the coating technology reduces the risk of outbreaks and contamination, ultimately benefiting both food processors and consumers alike.

The development of this coating technology was made possible through collaborative efforts involving not only researchers from Texas A&M University but also contributions from Dankook University in Korea. Funding for this research was provided by various grants, including the Food Manufacturing Technologies Program grant, Specialty Crop Research Initiative grant from the USDA National Institute of Food and Agriculture, and the National Research Foundation of Korea grant, underscoring the collaborative and interdisciplinary nature of the project.
