Lipid-based Materials in Edible and Non-edible Food Packaging

Abstract

Petroleum-based packaging materials, which are widely used for packaging applications, are non-biodegradable and have a negative impact on the environment. Packaging materials derived from biological sources are becoming very popular because of their sustainability, biodegradability, and non-toxic nature. However, poor mechanical, barrier, and antimicrobial properties are some challenges that must be dealt with. Lipid-based packaging films and coatings are used extensively to replace plastic packaging materials due to their excellent barrier activity and robust antimicrobial properties against common foodborne pathogens. Different lipids, such as essential oils, waxes, and fatty acids, are used in forming films and coatings. These compounds help enhance the shelf life and retain the quality of food products by inhibiting microbial growth, retarding lipid peroxidation, and preventing water loss from the samples. Therefore, this chapter will focus on the recent advancements and practical applications of lipid-based food packaging.
