Hydroxytyrosol (bijproduct olijfolie) in PVA folie voor voedsel

21 november 2016

Hydroxytyrosol (HTyr) is a biophenol found in extra-virgin olive oil or olive oil by-products. It is well known for its strong antioxidant activity. Researchers at the University of Perugia in Italy used HTyr as an active ingredient for a poly(vinyl alcohol) (PVA) matrix to develop film formulations by solvent casting process.
Morphological investigations showed evidence of homogeneity of all PVA/HTyr films, while the presence of HTyr clearly accounted for an increase of the crystallinity degree of the polymer matrix and also for providing antioxidant activity of the final films.
An article about the research is published in the Journal of Renewable Materials.
