What are the benefits and risks of using nanomaterials in food contact materials?

3 Regulation of nanomaterials

The regulation of nanomaterials in food contact materials is still evolving and varies across different countries and regions. There is no universal definition of nanomaterials, and no specific legislation or standards for their use in food contact materials. However, some general principles and guidelines apply, such as the precautionary principle, the risk-based approach, and the case-by-case assessment. The European Union (EU), for example, has adopted a definition of nanomaterials based on their size range (1-100 nm), and requires that any food contact material containing nanomaterials should be authorized and labeled accordingly. The EU also provides guidance on how to conduct risk assessment and risk management of nanomaterials in food contact materials, taking into account their exposure, hazard, and uncertainty. Other countries and regions, such as the United States (US), Canada, Australia, and New Zealand, have similar or different approaches to regulate nanomaterials in food contact materials, depending on their existing frameworks and scientific evidence.

4 Assessment of nanomaterials

The assessment of nanomaterials in food contact materials is a complex and challenging task, requiring multidisciplinary and collaborative efforts from various stakeholders. The assessment involves several steps, such as the identification and characterization of nanomaterials, the evaluation of their migration and exposure, the determination of their toxicity and effects, and the estimation of their risk and benefit. The assessment also requires appropriate methods and tools, such as analytical techniques, in vitro and in vivo models, computational methods, and nanosafety databases. The assessment also faces several limitations and uncertainties, such as the lack of standardized methods and protocols, the variability and diversity of nanomaterials and food matrices, the scarcity and quality of data and information, and the ethical and social implications of nanotechnology.

5 Future of nanomaterials

The future of nanomaterials in food contact materials depends on several factors, such as the innovation and development of new nanomaterials and applications, the consumer and market acceptance and demand, the regulatory and policy frameworks and harmonization, and the scientific and technological advances and challenges. Nanomaterials in food contact materials offer great opportunities for improving the quality, safety, and functionality of food products, but also raise concerns about their potential adverse effects on human health and the environment. Therefore, a balanced and responsible approach is needed to ensure that the benefits outweigh the risks, and that the ethical and social aspects are considered. Nanomaterials in food contact materials should be designed, produced, used, and disposed of in a safe and sustainable manner, with the involvement and participation of all relevant stakeholders.
