Nanoscale coatings in food packaging for extended protection against microorganisms

Abstract

Today, several packaging materials have been produced to preserve the quality of food products, prevent their spoilage and protect them against external factors for transporting food safely to consumers. On the other hand, the materials used in the production of packaging materials pose a significant risk to environment and human health. In addition, significant quality losses occur during the period from post-harvesting of fruits and vegetables to handling due to the microorganisms such as bacteria and fungi leading to the food spoilage. These losses during harvesting and post-harvesting affect our economy in a negative way. Therefore, new package materials are required in order to reduce the quality loss of food products during storage and transportation. A potential solution is in coating the surfaces with water-based nanotechnologic material providing elastic and glassy layer in nanoscale. This approach reduces the diseases of fruits and vegatables after post-harvesting and extend the self-life of food products. The colorless, oderless and non-toxic Trialkoxysilane Functionalized Quaternary Ammonium compound form nanolayers on the surfaces and inhibit the growth of microorganisms. This solution provides the highest level of antimicrobial protection and offers new solutions by reducing the risks to human health and the environment. This patented compound, Antimic® can be coated on the surfaces of packaging materials: paper, carton, glass, plastic, wood and metal. In addition, Antimic® can be applied in food stores by spraying technique. Pilot scale studies have shown that post-harvesting diseases of fruits and vegetables can be controlled
