Abstract

Natural nanocomposites occupy a huge arena in the developing industries related to food and medicine. Nanomaterials are mainly used to strengthen the polymer matrix and their dimensions range from 1 to 100 nm. They also enhance the mechanical, thermal, optical, physical and chemical features of the polymeric materials as compared to their virgin structures. Examples of different nano-based composite materials have been identified in the recent era. Out of those, starch and clay are the most common ones. Other natural materials like chitosan, agar, proteins and their blends are also recognised by the researchers. Nano-based composites, offering antimicrobial properties, have been studied extensively in the recent past due to its applications in food packaging industry, so that the packages can be hygienic in nature and prevent the growth of bacteria causing food borne diseases such as Staphylococcus aureus (Gram-positive) and Escherichia coli (Gram-negative), etc. However, it has limitations like when food is packed in such packages containing such preventive film, needs a high content of the antimicrobial material in the film that leads to the enhancement of the food shelf period and thus there is a scarcity of the main antimicrobial agents. The use of various starch incorporated antimicrobial films can reduce this imitation. This chapter mainly deals with the evaluation of the antimicrobial properties of different starch-based materials containing different nanocomposite films, which have their wide range of applications in the field of biomedicines and food packaging.
