Interestingly, they observed a decline in the populations of these pathogens after the introduction of APFs. The researchers further deposited the antimicrobial fibers on avocados. They noticed that the APF coating prevented the growth of pathogens on the fruit and protected the same from spoilage and damage. Thus increasing the shelf life of avocados by about 50 percent.
Whereas plastic packets often release harmful chemicals into our food and take more than 400 years to biodegrade, the APF coating is a naturally derived biodegradable and non-toxic biopolymer that does not impact the quality of the edible it covers (a previous study also highlights that humans can digest pullulan). Moreover, according to the researchers, it can be easily washed off from a food item using water and takes only three days to completely decompose in the soil.
Excited with these results, Demokritou wrote, “What we have come up with is a scalable technology, which enables us to turn biopolymers, which can be derived as part of a circular economy from food waste, into smart fibers that can wrap food directly. This is part of the new generation, ‘smart’ and ‘green’ food packaging.”
Sayonara you evil plastic food wraps.https://t.co/zQKdti4P0C
