Novel applications of silver-nanoparticles in food contact material: A systematic review

Purpose – The purpose of this study is to outline the gap of knowledge in the current legislation and regulations regarding the use of silver nanoparticles (AgNPs) in novel applications and to present the risks in those gaps for further consideration.
Design/methodology/approach – A systematic literature review, using exclusive keywords, specific inclusion and exclusion criteria and quality assurance was used to consolidate information from accredited databases and present relevant regulatory context applicable to the application of AgNPs.
Findings – The results of this study indicated that there are no specific legislation and regulations regulating AgNPs in the food industry. Hence, there is a gap in governance and there is ambiguity regarding their risk. This is causing a quandary for the regulators and manufacturers when trying use these particles in applications.
Practical implications – Although this technology is very useful to solve real-world concerns, this uncertainty in practice for researchers, developers and manufacturers prevent nanotechnology from recaching its full potential.
Social Implications – The inconsistency among experts causes misperceptions among potential customers or consumers on the safety of products containing AgNPs.
Originality/value – This study provides valued insights concerning the potential of using AgNPs in packaging material. It will also provide mitigation around the risks associated with AgNPs, with a view of protecting consumers from any potential toxic effects identified. Moreover, the study evaluates the gaps of knowledge in the current legislation and regulation and the danger of those gaps being overlooked for future applications. The adoption of a systematic review is a suitable data collection tool as it allows this paper the rigour to gather information and views of among peers
