The use of nano natural edible coating and films to Prolong Shelf Life of fruit & vegetable

Abstract

Nanotechnology is considered to be materials through which we control the construction of molecules in the specific size and shape, and with the difference of these molecules and compounds, the physical and chemical properties differ from them in the normal case, and from this we can develop nanotechnology at the atomic and molecular level at longitudinal levels from 1-100 nanometers. Thousands of shapes and sizes of different properties are produced for us from the same Nano metric material (depending on the structure of the particles of the material). The physical and chemical properties differ from them in the normal case, and therefore these materials take on new qualities that did not exist before. The modern world has tended to expand the production of nano natural edible coating and films and its technological applications on It is widely used in packaging and covering many types of vegetables and fruits because they do not interact with foodstuffs at room temperature and refrigeration. In gas and steam exchange and prevent corruption food is known as safe food film or functional film, which protects the food product from corruption, resists microbes and prevents oxidation, and in general, it consists of raw materials of plant or animal origin, as it is considered a thin barrier layer used as healthy and safe alternatives to traditional packaging materials harmful to human health and the environment where it is treated the food product, whether fresh or processed.
