Nanotechnology offers many potential applications across the supply chain which could result in a more sustainable agriculture and food system. However, considerable challenges still exist in realising its potential, including consumer acceptance. This research examines consumer perspectives on two different nanotechnology applications (in packaging for chicken fillets and in cheese) using conjoint analysis. A face-to-face survey of 1046 Irish adults was undertaken. It finds that technology has a significant impact on consumer food choices (higher levels of acceptance with traditional technology rather than nanotechnology), that different applications of a technology can result in varying levels of acceptance (higher acceptance for nanotechnology in packaging of chicken fillets rather than in the cheese product) and that offering salient benefits (e.g. health or lower price) can off-set technology concerns in some but not all instances. Differences amongst consumer segments also exist with price having low utility for “health focused consumers” but having high utility for “conventional consumers”. This research provides industry with an overview of consumer perceptions around two potential nano-inside and nano-outside product applications elicited through a nationally representative quantitative survey (n = 1046). The results from this work can contribute to the development of a research commercialisation strategy that will yield products and processes of value to consumers, and thus will have greater likelihood of acceptance. Moreover, this work points to the need to involve consumers at an early stage in the product development process and in considering potential commercialisation pathways, particularly with regard to food production where consumers may be especially sensitive or risk-averse. Appreciating the concerns and preferences of consumers and eliciting their overall level of acceptance with regard to particular technologies and product applications is crucial for their success. •Consumers display varying levels of acceptance to nanotechnology food applications.•Acceptance is strongly influenced by the particular application and benefits offered.•Salient benefits can off-set technology concerns in some instances.•Different benefits find favour with particular consumer segments.
