The food we get from market wrapped in a plastic paper which although decreases spoilage but there are also some drawbacks as they are difficult to destroy and creates a waste that can block landfills and our oceans for long time.
In this regard, many biodegradable have been studied by the researchers which are potential replacements and now a research team has used the milk protein casein in order to create a packaging film that is degradable, edible as well as much better in preventing spoilage than plastics.
Casein Biodegradable wrapping is an environment friendly replacement to all plastic and petroleum based packaging options that are increasing in the market. In this process, a casein coating is fine tuned by the researchers, which is making improvements in some designs flaws from earlier.
It is dissolving too quickly in water and possessing a higher susceptibility for both high temperatures and humidity. These biodegradable films are made of milk protein and have the efficiency to keep food fresher and replace plastic wrapping. This technology is currently being tested by researchers for edible food wrappers.
These coating applications in this process are endless and efficient. This casein film has much smaller pores than existing packaging options and makes it up to 500 times better than plastics at locking out oxygen.
These protein based films are powerful in oxygen and that’s why they can prevent food spoilage. They can prevent food wastage at the time of distribution along the food chain. These films are quickly biodegradable when thrown out.
