Edible packaging is primarily made of polysaccharides, proteins, and lipids, which are biopolymers.
These biopolymers are used to create edible films or coatings that can act as packaging. Here's a breakdown:
-
Polysaccharides: These are complex carbohydrates. Common examples include:
- Starch and its derivatives
- Gums (like those from seaweed or plants)
-
Proteins: These are complex molecules made of amino acids. Examples include:
- Gelatin
- Gluten
-
Lipids: These are fats, oils, and waxes.
These materials are combined and processed to form thin films or coatings that can encase food products, providing a barrier against moisture, oxygen, and other environmental factors. This offers a sustainable alternative to traditional packaging materials and can even be consumed along with the food it contains.
