Fresh Vegetables and Fruits start to ripen after harvesting and during the ripening process, the fruits and vegetables release ethylene gas. This ethylene gas when in the package increases the ripening rate of the fresh produce hence aggravating the ripening process resulting into faster rotting of the fresh produce.
They ethylene gas produced works as a auto catalyst for ripening which in turn produces higher sugar levels causing microbial spoilage of the fruits
The plastic articles produced by using KEEP-IT-FRESH MB absorb the harmful ethylene gas produced hence slowing the ripening and rotting process and increasing the shelf life of the packed produce.
The film produces shows upto 4 times increase in the shelf life of Bananas kept without packaging and improves the shelf life of Tomatoes by upto 3 times.
Tests performed on the Tomatoes show that the tomatoes kept in open started to rot in 5 days where as the ones in the KEEP-IT-FRESH bags were good even on the 10th day compared to the ones in generic plastic bag.
