Acceptance of nanotechnology applications and satisfaction with food-related life in southern Chile

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 sunflower 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.

Acceptance of a food of animal origin obtained through genetic modification and cloning in South America: a comparative study among university students and working adults

AbstractWith the aim of comparing the acceptance of milk obtained from cloned, genetically modified (GM) and conventionally bred cows among working adults and university students, and identifying and characterizing typologies among both subsamples in terms of their preferences, a survey was applied to 400 people in southern Chile, distributed using a simple allocation among the subsamples. Using a conjoint analysis, it was found that consumers preferred milk from a conventional cow. Using a cluster analysis, in both subsamples two segments sensitive to production technology were identified. Rejection of cloning was greatest among university students, whereas a higher proportion of working adults rejected GM. The segments differed in terms of area of residence, knowledge about GM, and milk consumption habits. Contrary to what was expected, no differences were found according to education, gender or degree of satisfaction with food-related life.
