Experts from Harvard University USA and Nanyang Technological University (NTU) Singapore have developed transparent, durable and eco-friendly bags made from corn husks that hold fruits and vegetables for up to a week.
These plastic-looking bags are additionally biodegradable, meaning that after a short period of use, they automatically dissolve into harmless substances and thus do not contribute to environmental pollution.
They are made with the help of a method called ‘electro-spinning’, while in the manufacture of these bags, in addition to the substance ‘zein’ remaining after making ethanol from corn, fiber containing starch, cellulose and other natural polymers ( Fibers) have been used.
During the initial experiments, when fresh strawberries were wrapped in these bags, they remained edible for a week, after which they began to develop mold.
These bags are additionally antiseptic, meaning that when the germs that cause rot and rot are removed from the wrapped vegetables and fruits, these bags begin to release antimicrobial substances in response.
Thus the food stored in them stays in good and usable condition for many days without any special arrangement.
“In this way, we can develop sustainable and environmentally friendly technology for food packaging that will keep mold and germs away (preserved items) and will be extremely useful for the food industry,” said a professor at Nanyang Technological University. Marie Chen, who is also the lead scientist in the study, said.
