Does the label 'unconventional food plant' influence food acceptance by potential consumers? A first approach

In the Brazilian context, many plants have been marketed under the name of unconventional food plants (UFPs). However, it is not known whether this label causes some bias in product acceptance. Thus, two case studies were conducted to fill this gap. The research also sought to determine if the type of fair (agroecological vs. common) where the UFP is sold, the familiarity with the term, and the identification of a UFP when used as an ingredient act as moderating variables of this relationship. This paper presents data from two case studies. The first was conducted with jenipapo juice through sensory evaluations at a conventional fair and an agroecological fair in the metropolitan region of Maceio (Northeast Brazil). The product was offered to some attendees without giving them any information, while for other attendees, the presence of a UFP and the underlying concept were mentioned. In this context, the UFP label did not affect the sensory evaluation. In the second case study, taioba cakes were offered to students from a public university in the same city. In this context, the UFP-labelled product was less accepted than the product without the label only for students who had not heard of UFPs. The differences between the two case studies reinforce the need to expand research on this topic to identify in which contexts the UFP label influences sensory evaluations.
