This article reviews the applications of cellulose nanocrystals and cellulose nanofibers in edible food packaging films, showing that their addition can significantly improve film properties, but there is an optimal concentration limit.
Due to the environmental pollution problems caused by plastic-based packaging the development of edible food packaging films is imminent. However, the performance of most edible packaging films is insufficient to meet practical applications, so recent studies have focused on the research of various fillers to improve film properties. This article reviews recent applications of cellulose nanocrystals (CNC) and cellulose nanoriber (CNF) in edible food packaging films including the effect on thickness, optical properties, barrier properties, water sensitivity, mechanical properties, antioxidant and antimicrobial properties. The main conclusion of this review is that the incorporation of CNC and CNF could significantly improve the performance of edible food packaging films. Particular finding is that although CNC and CNF can be used as excellent addition to improve the performance of edible food packaging films, there is a key optimum concentration. In addition, we also found that CNC and CNF as excellent controlled release agents and stabilizers significantly increased the antioxidant and antibacterial properties of edible food packaging films.
