Description

A pineapple a day keeps the doctor away. Pineapples aren’t just delicious fruits, they also help wounds heal faster, according to new research. Brazilian scientists created a wound dressing made from pineapple husks, the part of the fruit that normally gets thrown away.

The key ingredients are bromelain, a protein that breaks down other proteins; and nanocellulose, a byproduct of fruit-eating bacteria known as a ‘wonder material’ for its strength and flexibility.

Pineapple waste is an abundant resource, so the materials are renewable and cheap. Scientists say in the future, nanocellulose could be used to replace body parts.
