Rediscovering Portuguese White Crowberries (<i>Corema album</i>): Cultural Insights and Nutritional Significance
Abstract
White crowberries (Corema album) are a fruit from an endemic shrub found in Southern European Atlantic costal dunes. Although this shrub and its fruits never became a formal commercial crop for a number of reasons, it has a long-lasting relevance and tradition, much associated with summer, beach and holidays. The main goal of this study was to conduct a thematic analysis of the words and small expressions people associate with white crowberries. For that, a questionnaire was used, and the participants were asked to indicate in an open-ended question which top-of-mind words/small expressions they associate with white crowberries. A total of 501 people participated in this study, of which only 394 knew about white crowberries, and from those, only 229 answered the open-ended question of interest to this purpose. The results showed that the words/small expressions given by the participants were distributed between five categories (1—Memories of places, people and times, 2—Emotions and experiences, 3—Sensorial perception, 4—Properties and uses, and 5—Natural resources’ valuation). Additionally, 18 subcategories were also identified. The most representative of the categories was sensorial perception and the most relevant of the subcategories was habitats (a subcategory from category 1). The most frequent words mentioned by the participants were beach, berry and summer. In addition, the effect of sociodemographic groups was investigated and some variations were observed in the categories of the words mentioned by the participants according to sex, living environment or region. This work allowed for the identification of a high variability in the words or expressions that account for a rich patrimony of tacit knowledge, memories, emotions and perceptions of the population towards white crowberries, thus confirming their social as well as nutritional relevance.
