Abstract
With the growing awareness of plastic pollution, the need for sustainable alternatives has been more urgent. Bioplastics and biodegradable plastics present promising solutions that can help us reduce our environmental impact. Embracing these innovative materials is a vital step toward a cleaner, greener future. Vietnam is a country that uses packaging such as nylon bags and plastic products in large quantities. The use of plastic packaging puts a lot of pressure on environmental protection. Therefore, packaging made from natural and biodegradable materials is the current trend. Biodegradable materials used to develop bio-packaging are cellulose, pectin, chitosan, starch and protein extracted from plant and animal sources. Among them, seaweed is one of the potential biopolymers in biofilm applications. Gelling agents found in seaweed are mostly carrageenan, ager, alginate, these substances have the ability to form good biodegradable films and have properties that help them to be commercially applied as additives used in the food industry, as gelling agents, emulsifiers, stabilizers and thickeners, but they are gradually recognized as valuable materials, so it is necessary to strengthen basic research to discover new functions, make the most of its potential, especially in the production of biodegradable films. Biofilm made from gelling agent is one of the potential applications for creating biofilm with antibacterial properties to help preserve food, while also helping to reduce waste polluting the environment with biodegradability. The gelling agent is isolated from Kappaphycus alvarezii through the green method, which is the preprocessing by sonication and gelling agent is isolation by the temperature, these results were reported in the National Conference in Vietnam. In this study, biofilm made from gelling agent, which was isolated from Kappaphycus alvarezii, is reported first time. The biofilm show that the ability applied packaging and biodegradable materials used to develop bio-packaging.
