Compostable packaging as effective as conventional plastic for shelf-life of fresh produce: Study

The results cast new doubt on the claim that conventional plastic packaging is the only possible solution for preserving freshness on the market

Compostable packaging is as effective as conventional plastic and may even outperform it for the shelf-life of fresh produce, two peer-reviewed studies have revealed.

 

The results cast new doubt on the claim that conventional plastic packaging is the only possible solution for preserving freshness on the market.

 

Scientists at the Agricultural Research Organisation (ARO), The Volcani Institute (Israel), used cucumbers and bell peppers to test the differences between compostable packaging and conventional plastic packaging.

 

They found compostable packaging enables shelf-life of bell peppers up to 21 days and cucumbers up to 15 days, even better than conventional plastic. The compostable packages used were purchased from Israel-based TIPA Corp.

 

In the studies, part of the produce remained unpacked as control, while other produce was packaged in non-perforated, micro-perforated and macro-perforated compostable packaging or commercial micro-perforated polypropylene packaging.

 

Afterwards, half the samples were continually stored at 22 degree centigrade to simulate extended shelf conditions, while the other half were stored for two days at 15 degree centigrade, a further two days at 22 degree centigrade and then up to six weeks of home refrigerator storage at 4 degree centigrade to simulate farm to fork supply chain conditions.
