Researchers from Samara State Technical University, Russia, have created a packaging based on fruit or vegetable puree which consists of natural ingredients. Moreover, the product is very low on caloric value, thus can be considered dietary.
As per the production technology, fruit and vegetable puree is taken as a liquid mass with a plasticizer, and then the mass is dried at a temperature of no higher than 60 degrees Celsius. At higher temperatures, the packaging becomes too brittle. The team members created more than 500 experimental edible films samples. The samples carry high level of material strength and are able to compete with the materials obtained from cellulose. Currently, the team is trying to patent their invention.
In addition, scientists are experimenting with fruit raw materials and developing apple dishware and cosmetic masks based on apples with the introduction of plant extracts.
