Preferences for oil produced conventionally, produced with nanotechnology or genetically modified in the Araucanía Region of Chile. Cien. Inv. Agr. 40(1):17-29.

SUMMARY

In light of the increasing use of nanotechnology in food production, consumer acceptance of sunflower oil produced with nanotechnology or from genetically modified (GM) plants and the conventionally produced raw materials available in Temuco (Araucanía Region, Chile), market segments were differentiated with respect to their acceptance of nanotechnology and characterized according to their sociodemographic characteristics and food neophobia level. To achieve this aim, a survey was administered to 400 people. Using a conjoint analysis, the brand (33.6%) and production system (32.6%) were determined to be more important than the price (19.2%) and health certification (14.6%); national brands, produced conventionally with a health certification seal and sold at the lowest price, were preferred. A hierarchical cluster analysis identified three main segments. The largest (45.5%) preferred oil made with nanotechnology. The second (29.75%) preferred conventional oil and oil made with nanotechnology. The third (20.75%) preferred conventional oil and rejected oils made with nanotechnology and GM. The segments differed significantly according to marital status and according to the score on the food neophobia scale. Approximately 75% of the sample had a positive response to the oil produced with nanotechnology, and this positive response was related to the food neophobia score.Considerando el creciente uso de la nanotecnología en la producción de alimentos, se evaluó la aceptación de aceite de maravilla producido con nanotecnología, con materias primas genéticamente modificadas (GM) y producido convencionalmente en consumidores de Temuco (Región de La Araucanía, Chile), se diferenciaron segmentos de mercado en relación con la aceptación hacia la nanotecnología y, se caracterizaron según sus características sociodemográficas y nivel de neofobia alimentaria, mediante una encuesta a 400 personas. Utilizando análisis conjunto se determinó que la marca (33,6%) y el sistema de producción (32,6%) fueron más importantes que el precio (19,2%) y una certificación sanitaria (14,6%), con preferencia hacia el aceite con marcas nacionales, producido convencionalmente, con sello de certificación sanitaria, al menor precio. Mediante análisis de conglomerados jerárquicos se diferenciaron tres segmentos principales. El mayoritario (45,5%) prefirió el aceite producido con nanotecnología. El segundo (29,75%) prefirió el aceite convencional y con nanotecnología. El tercero (20,75%) prefirió el aceite convencional y presentó alto rechazo hacia los aceites con nanotecnología y GM. Los segmentos se diferenciaron significativamente según estado civil y en los puntajes de la escala de neofobia alimentaria. Aproximadamente el 75% de la muestra tuvo una respuesta positiva hacia el aceite producido con nanotecnología, lo que se relaciona con el nivel de neofobia alimentaria.
