ABSTRACT
Nanostructures are one of the most important inventions because they have a lot of applications in many medical and industrial fields. Nanostructures can be used to improve the safety and quality of foods as well as to produce novel food ingredients or supplements. Biopolymers from food industry waste are useful as raw materials for nanostructures synthesis because they are abundant and non-toxic, and they give to nanostructures some specific and benefit characteristics. Different biopolymers are extracted from natural sources such as wall cell plants, crustacean, and seaweeds. This review gives important evidence about the use of cellulose, lignin, chitosan, alginate, and carrageenan to obtain nanostructures.
