Odour-defeating nanocellulose film developed by Swedish researchers

A team of academics from Sweden has published a paper describing progress in designing a food packaging film that eliminates odour from aromatic foods like onions and cheese.

The researchers are employing cellulose nanofibrils (CNF) – a nanostructured preparation of wood fibres – to create flexible films that trap the sulphur often responsible for bad smells.

Analysis showed that the CNF–zeolite films were able to reduce the levels of negative odours below the level detectable by the human olfactory system.

The work is described in the paper Nanocellulose–Zeolite Composite Films for Odor Elimination, published in the journal ACS Applied Materials & Interfaces on 10 June.
