Edible Coating to Prolong Shelf Life of Fruits and Vegetables
Context: A team of researchers have developed an edible material that can extend the shelf-life of fruits and vegetables.

- The specialised coating was created using a mixture of two substances: micro-algae extract and polysaccharides.
- The marine microalgae Dunaliella tertiolecta, is often used as a source of algae oil, which is a health supplement.
- The microalga is known for its antioxidant properties and has various bioactive compounds such as carotenoids and proteins.
- The coating is non-toxic and could be safely used as an edible food packaging material.
- It also had excellent UV-Vis light-blocking properties.
- The material can be either directly coated on the vegetables and fruits or made into a vegetable storage pouch. In both cases, the shelf-life of the vegetables can be extended.
- It can help preserve vegetables and fruits for as long as two months.
