Preferences For Berries Among Consumers in Southern Chile: Blueberries Are Produced But Are They Consumed?

This document discusses a study on consumer preferences for blueberries, strawberries, and raspberries in southern Chile. The study aimed to evaluate preferences for loose versus packaged/branded berries sold at different prices, and identify consumer segments based on preferences. A survey of 400 people in the Araucanía region found that raspberries and strawberries were preferred over blueberries, and that consumers preferred packaged/branded berries sold at the lowest price. Two main consumer segments were identified: price sensitive consumers who preferred strawberries, and consumers sensitive to berry species who preferred raspberries and strawberries.

Preferences for Berries Among Consumers

in Southern Chile: Blueberries Are Produced


but Are They Consumed?
Berta Schnettler, Horacio Miranda, José Sepúlveda, Marianela Denegri, Marcos Mora, and Germán Lobos

Abstract: Blueberry plantations in Chile are oriented exclusively towards exports to northern hemisphere countries;
however, this fruit has recently been introduced into the domestic market due to the increased supply and a fall in
export market prices. Based on the previously mentioned, the objectives of the present study were to evaluate consumer
preferences for 3 species of berries (blueberries, strawberries, and raspberries), sold loose (unpackaged) as opposed to
packaged and branded, at different prices, in one of the principal blueberry producing areas of Chile; and to distinguish
consumer segments by their preferences. To do this a survey was applied to 400 people in the Araucanı́a Region of
southern Chile, who were responsible for purchasing fruit for their households. Conjoint analysis showed a preference for
raspberries and strawberries over blueberries, packaged and branded, at the lowest price. Total of 2 principal segments were
distinguished by cluster analysis: “price sensitive” (42.7%), who preferred strawberries, and “sensitive to species of berry”
(47.5%), who preferred raspberries and strawberries. The segments presented different profiles in their demographic
make-up and fruit consumption behavior. Strategies are discussed that might reverse the low acceptance of blueberries in
the Chilean domestic market.
