Abstract. While hands-on, focus-group-based testing may be used to measure consumer preference, other computationally-based
methods have also proven effective in testing opinions and sentiment toward a product. The IdeaMap
®
approach presents online,
human subjects with a suite of attributes that define a given product. The subjects rate the product as these attributes change
in various combinations. Upon analysis, individual attributes of the product, identified as consistently favorable or unfavorable,
become apparent. In applying this methodology to strawberries, three-hundred and six subjects representing a broad cross-section
of demographics from the United States were surveyed. The subjects rated perceived strawberry fruits based on appearance, texture,
health benefits, flavor, point of purchase, and how they were consumed. Results from these experiments define the individual
elements of a strawberry that contribute to or detract from an “ideal” strawberry experience. Furthermore, the results of this study
indicate that sweetness and complex flavors are the most important attributes, while perceived health benefits had little influence
on consumer preference. The point of purchase can have a strong positive or negative effect, depending on the demographic
fraction. Additional analysis of these results illustrate that there is not a single, perfect strawberry. Specific likes, dislikes and
preferences change with ethnicity, age, gender, urban or suburban location, education and marital status. The results from this
study can help shape breeding priorities as well as provide important guidance for marketing to specific demographics in the
interest of increasing strawberry consumption.

1. Introduction
The cultivated strawberry (Fragaria × ananassa Duch.) is an economically valuable small fruit crop with fruit
containing numerous, diverse chemical compounds that can benefit human health and nutrition. These compounds
include antioxidants (especially vitamin C and pelargonidin-3-glucoside) vitamin B6, ellagic acid, and folic acid
[1, 2]. Multiple lines of in vitro, animal or clinical evidence indicate that strawberry-prevalent compounds have
potential health benefits such as cellular anti-proliferative activities [3, 4], lipoprotein control and cardio-protective
effects [5, 6], maintenance of blood glucose levels [7], and prevention of specific digestive disorders [8]. The health
benefits alone provide a sound rationale to encourage greater strawberry consumption. Improved flavors and aromas
would likely further increase strawberry consumption.
