A few years ago, biotechnologists from Samara State Technical University took up the development of edible food film, which, according to scientists, could reduce the amount of waste from traditional plastic packaging. The product obtained by Samara scientists is made exclusively from natural ingredients, with no dyes or preservatives. Chemical processes that entail deep chemical changes are not required for production. The technology uses standard processes of the food industry (mixing, concentration, formation of layers of raw materials). First, scientists use fruit or vegetable puree to form a mass and add a plasticizer—a special natural adhesive substance whose composition is kept secret. After that, the finished layer is dried at a temperature not higher than 60 degrees C.
In 2018, the technology for creating edible packaging received three Russian patents and formed the basis of another ambitious project—edible dishware. The experiment began with glasses, since it is the most common type of disposable plastic dishware in the world.

Of course, there are already edible packaging and dishware products made from rice, coffee, avocado seeds, etc. but these products are only conditionally edible, since they contain artificial additives that are not completely absorbed by the human body. An adhesive substance used in the edible film and edible dishware is completely safe and made exclusively from natural plant materials. It is not obtained by chemical synthesis, it does not contain harmful impurities, it is widely used for the production of a number of food products.
In developing food film formulations, scientists experimented with raw materials from various fruits, berries and vegetables, including apples and carrots, currants and chokeberries, plums and strawberries, green beans, pumpkins and blueberries. However the scientists found that...
