In a collaborative effort to enhance the meals trade, Dr. Mustafa Akbulut, professor of chemical engineering, and Dr. Luis Cisneros-Zevallos, professor of horticultural science, have developed a two-step coating resolution for galvanized metal that’s extra hygienic and reduces the chance of corrosion.
Galvanized metal containers and surfaces are used for harvested produce due to their sturdiness, power and decrease price in comparison with stainless-steel. Nevertheless, micro organism residing in storage containers may cause corrosion.
The brand new coating will cut back corrosion by not less than 70 %, Akbulut stated.
“This materials is extra sturdy and does not expertise corrosion,” Akbulut stated. “The floor itself can repel the micro organism so it does not get germs caught on it. Regular metal tends to gather pathogens and microorganisms, however the coated metal is overcoming that problem. These are the principle advantages of this know-how.”
The coating methodology for galvanized metal reveals superhydrophobicity and antifouling capabilities, successfully inhibiting the attachment of fungi, micro organism and dirt. This analysis was printed within the Journal of Meals Engineering.
“This may have an effect as a result of the those that eat fruit and veggies belief that they are shopping for one thing secure, and it’ll not have an effect on their well being,” Cisneros-Zevallos stated. “Proper now, the trade does their greatest to cut back these dangers, however you’ll hear about outbreaks of those contaminations and folks getting sick. There are generally reported deaths due to these occasions.”
In the course of the coating course of, the fabric properties, structural properties and mechanical power of metal don’t change. Solely the very prime layer of the metal is coated, since that’s the place meals is available in contact with the floor, Akbulut stated.
Analysis exhibits that this coating decreases bacterial strains over seven days and reduces adherence to Aspergillus, a foodborne fungi.
This coating know-how can doubtlessly be used on grain storage silos, together with different food-related storage items and containers, in line with the article. This can be a vital boon to the multidisciplinary fields of meals engineering, security and processing.
The galvanized metal coating may also profit agricultural farmland, in line with Akbulut.
“Most of the food-produced commodities come to the commercial setting in some kind of soil, particles or mud,” Akbulut stated. “So, even when the produce is washed, these commodities may cause contamination. With this know-how, we’re decreasing mud-related contamination.”
With the knowledge gathered from the analysis, Cisneros-Zevallos stated they might finally adapt and make the most of these applied sciences to revolutionize fewer outbreaks and positively influence the meals trade.
“Our purpose is to make the trade undertake this,” Cisneros-Zevallos stated. “Processors will profit within the sense that they are going to be dealing with one thing that they will ship in a trustful strategy to shoppers, and shoppers will profit as a result of they may have one thing that shall be secure for them.”
From the sphere to the buyer, contamination could be minimized by utilizing these sorts of surfaces and avoiding cross-contamination, as defined by Cisneros-Zevallos.
“With this analysis, we’re making certain that the technological developments from different fields are being pursued and applied in agriculture,” Cisneros-Zevallos stated. “The agricultural subject is catching up with different applied sciences. This coating straight impacts our each day life and the meals we’re making an attempt to make safer.”
Contributors to the analysis embody doctoral college students Wentao Zhou, Shuhao Liu, and William DeFlorio from the Artie McFerrin Division of Chemical Engineering, together with Professor Jun Kyun Oh and doctoral college students Sang Ha Music and Hayoung Choi within the Division of Polymer Science and Engineering, Dankook College.
A Meals Manufacturing Applied sciences Program grant and Specialty Crop Analysis Initiative grant from the USDA Nationwide Institute of Meals and Agriculture supported this work.
This work can also be partially supported by the Nationwide Analysis Basis of Korea grant funded by the Korean authorities. The Division of Polymer Science and Engineering was supported by way of the Analysis-Centered Division Promotion & Interdisciplinary Convergence Analysis Venture as part of the College Innovation Assist Program for Dankook College in 2022.
