About this Research Topic
Nowadays, food quality and safety are major growing concerns of the food industry. Consumer demand for natural food products is increasing, but control of microbial growth in the packaging environment is essential in order to avoid food waste. The growth of spoilage microorganisms does not only reduce food shelf life, but also spreads pathogenic microorganisms, which can endanger public health.
Materials containing antimicrobials, also referred to as “treated” materials, have been introduced to the food packaging sector as a new active concept to improve both food preservation and safety. Active‐releasing antimicrobial systems can be generated in packaging articles by multiple routes such as the application of coatings or compounds absorbed on the film surfaces, the employment of volatile and nonvolatile substances directly incorporated into the inner plastic parts, the immobilization of antimicrobials onto polymer matrices by ion or covalent linkages, and also the use of polymer materials that are inherently antimicrobial. Furthermore, emerging research has suggested that a sustained release profile of biocides is needed for achieving long‐term protection functionality against harmful microorganisms.
Despite the promising results of research in this field, the potential application of antimicrobial packaging in the food industry still depends on further investigation exploring: a) the antimicrobial properties in open and closed systems that resemble actual packaging; b) the efficacy and safety of the antimicrobial packaging materials to control bacterial growth; c) the use of natural substances and sustainable food systems; d) the impact of the antimicrobial activity on food preservation; e) the controlled release capacity of treated materials into the food media; and f) the scale-up of the antimicrobial packaging production.
This Research Topic encourages research on antimicrobial packaging that is aimed at enhancing and/or improving food quality and safety by reduction of pathogen growth and extension of shelf life.
