Given the increasing use of nanotechnology in food production and packaging, its acceptance was evaluated in Temuco, Chile, and different consumer segments were identified. Different brands of sun/ower oil were used at different prices as a case study. A structured questionnaire was applied to 400 supermarket shoppers. It was determined that brand was more important than nanotechnology application in packaging and food, and more important than price. The consumers preferred an average priced oil with a manufacturer’s brand with nanoparticles to reduce cholesterol, and packaging with nanoparticles to increase the shelf life of the product and to prevent the growth of microorganisms. Three consumer segments were distinguished by the cluster analysis. The largest segment (44%) preferred the oil without nanotechnology. The second (35.2%) preferred the oil with nanotechnology in the food and the packaging, and the greatest preference was for packaging with nanoparticles extension in the shelf life of the product. The third segment (20.8%) had similar behavior, but it showed greater preference for the oil with nanoparticles that reduced cholesterol and for the packaging that prevented the growth of bacteria and viruses. The segments differed in terms of their satisfaction with food-related life and lifestyle. It was found that over 50% of the participants preferred oil with nanotechnology applications.
