Coatings over the meals prodcan is usually accomplished by spread coating, spray coating, dip coatings methods [4]. In ucts be accomplished by spread coating, spray coating, oror dip coatings techniques [4]. Within this section, all three procedures might be discussed in detail.3.2.1. Spread CGP-53353 Formula coating The spread coating method could be the easiest system of polymeric coating more than the surface of meals merchandise and packaging supplies (Figure 12). There isn’t any requirement for employing a sophisticated instrument. As a result of this reason, this strategy may be simply adapted by small-scale industries with no substantially monetary burden. In this strategy, the polymer solutions are straight applied more than the meals solution or packaging components employing a sterile brush or spatula [4]. The polymer option may include various additives (e.g., crucial oils, nanomaterials, and plasticizers, etc.) that would increase the physical, barrier, and mechanical properties and improve the coatings’ functionality (e.g., antimicrobial and antioxidant). As soon as the polymer solution/mixture is coated more than the food merchandise, the food items are dried beneath sterile situations. For this goal, a laminar flow cabinet might be made use of [4]. Just after the liquid coating layer is dried to form a thin film, the meals prod-Int. J. Mol. Sci. 2021, 22,12 ofucts are subsequently packaged and stored under the specified storage conditions for the food items. The coating on the packaging components that do not have functional properties, like antimicrobial and antioxidant properties, could be carried out similarly. The coating imparts added offered properties to the packaging supplies. By way of example, coating the paperbased packaging material with chitosan coating imparts antimicrobial and antioxidant Int.

Further, such a coating technique improves moisture retention without the need of compromising the mechanical properties [4].11.
