Tweelaagse PVA/chitosan-folie voor aardbeienverpakking

Strawberries are among the most popular fruits worldwide. Researchers at Sichuan Agricultural University in China tested strawberry packaging based on four different chitosan–poly(vinylalcohol) blend films with chitosan contents of 0 wt %, 20 wt %, 25 wt %, and 30 wt %.
They found that strawberries packaged using these films showed significant differences in weight loss and firmness, decay percentage, titratable acidity, total soluble solids and ascorbic acid content when compared to non-packaged strawberries. The findings suggest that the 25 wt % chitosan films can be used to extend strawberry shelf lives while maintaining quality levels. An article about the research is published in Coatings.
