تاثیر بهره گیری از ذرات نانو در بسته بندی بر روی زمان ماند فراورده های غذایی
The effect of applying nano particles in packaging
on the shelf life of food products
Abstract
Packaging serves as the cover of products and therefore makes the first impression on the customers. Nanotechnology is one of the recent methods of choice in packaging for increasing the quality and safety of foods. Having unique physical and chemical properties, nano particles are commonly used in nanotechnology and other scientific fields with extensive applications. New properties can be seen in silver particles if the size of particles is reduced to less than 100 nanometers. These new properties of nano particles are related to the surface to volume ratio. Applying nanofilms in packaging (SPN) aims to increase the shelf Life and preserve the freshness of the foods. Antimicrobial properties of silver nano particles against the microbial organisms is effective on an extensive spectrum of bacteria. Released nano particle following the contact with bacteria not only affect those bacteria but also other microorganisms. Results show that applying silver nano particles in packaging can increase the shelf life of food products
