Biofilm of potato starch and silver nanoparticles

The biofilm and covering have been used to promote the change and improve the natural peel of diverse fruits, to prevent the loss of humidity, to allow the interchange of gases, to provide sterility and conservation. Therefore, in recent years a growing interest in the organic films has emerged, this organic films are very diverse, highlighting the potato starch based biofilms. In this investigation some silver nanoparticles were synthesized by the chemical reduction process and were used as covering in fruits to avoid the growing of bacteria in strawberry and apples in conditions of room temperature to maximize the lifetime in shelf of this perishable fruits.
