36 characteristics to describe blueberries

373

The objective of a 2014 research study was to identify the choice parameters of US consumers in their decision to purchase fresh blueberries .

In two different periods (2011 and 2013), 306 and 300 consumers respectively responded to cards containing a combination of attributes to describe blueberries; the panel was then asked how likely they were to buy a fruit with those attributes.

For example:

WITH WHAT PROBABILITY (FROM 1 TO 10) YOU WOULD BUY A FRUIT WITH THESE CHARACTERISTICS: FLOURY, KNEADED, DRY | LIGHT BLUE BERRIES | VERY SWEET, NO NEED TO SUGAR | NO FAT, NO CHOLESTEROL

The characteristics identified by the researchers that have been combined to investigate consumer preferences have been grouped into 6 categories (hardness, texture, size, colour, flavour and aroma, nutritional characteristics) and each in 6 descriptive elements.

These 36 elements can be used to provide a broad overview of the expressions that a consumer associates with the consumption of blueberries; they thus provide practitioners with a guide to the different aspects that are assessed when buying and repurchasing.
