Abstract

Due to environmental issues caused by plastic packaging and growing consumer demand for fresh and safe food, there is a growing interest in antibacterial active food packaging films/coatings containing plant essential oils (EO). For the effective use of EO-incorporated active films/coatings, EO must be effectively integrated encapsulated in active films/coatings, and the integrated encapsulated EO must be released from active films/coatings slowly during storage to exhibit antibacterial effects more durable. Recently, several promising strategies have been proposed to improve the sustained release and retention enhancement of EO in active films/coatings, including particle encapsulation, nanoemulsion, Pickering emulsions, multilayer system, and electrospinning technology. This article reviewed the latest technologies of sustained release and retention enhancement strategies for encapsulating EO in active films/coatings. The advantages and disadvantages of these sustained release and retention enhancement strategies and their practical applications in food preservation are also introduced.
