Researchers at Harvard University have developed a spray that covers food and serves as a container so that they don’t spoil.
It is a solution to the use of plastic made from a fungus mixed with water which is applied directly on the food in question. Just by washing it with water, the layer disappears and the product is ready to consume.
It is an invention with several advantages and it is that makes the product stay fresh 50% longer, which helps reduce food waste. It also has antimicrobial properties: it protects food from pathogens that spoil it and transmit diseases, which increases food safety.
In addition, it can be eaten, according to its creators, and it is cheap to produce. The most important thing is that it is biodegradable, does not pollute and decomposes in three dayswhich places it as an alternative to the plastic pollutant.
The problem with this spray is that a method to quickly apply it to food has not yet been developed And it has to be done one at a time.
