Core objective of EU-funded NanoPack project is to extend shelf life and quality of fresh produce, bakery and proteins. Active materials tested with wide range of products have shown remarkable results.
Fresh cherries, which were packed in NanoPack antimicrobial film, containing low concentration of various natural essential oils, exhibited an increased shelf life of 40%. The cherries were packed in bags made of NanoPack film and commercial film were stored at the same holding temperature for 14 days and then transferred to an ambient temperature for 4 days. The results have shown that NanoPack film extends the shelf life of cherries by 2 days. Only 33 % of the cherries packaged in commercial film were saleable, compared to the 73 % using the NanoPack material. This two-day increase in shelf life corresponds to an added value of 40% increase in their saleability.
