Abstract

Purpose

The number of researches that evaluate how behavioural and personality issues affect consumers’ acceptance and perception of food is increasing. Thus, this study aimed to evaluate the effect of nutritional information and health claims related to soya and cashew nut beverages over consumers’ acceptance and perception regarding nutritional value and healthiness and to verify whether behavioural and personality issues affect such evaluation.

Design/methodology/approach

The samples were evaluated in two phases, with (blind phase) and without information (informed phase) about their composition, nutritional characteristics and functional claims related to some of their ingredients. The sensory evaluation data were analysed by means of the analysis of variance for repeated measures, applying 2 (information) × 2 (beverage) and generalised linear model to evaluate the effect of information over the acceptance averages, as well as over the perception of healthy food and nutritional value.

Findings

Information on composition, nutritional characteristics and functional claims related to the cashew nut and soya beverages did not influence flavour acceptance (p-value = 0.250) and overall impression (p-value = 0.316), but had a positive impact on consumers’ perception regarding healthiness (p-value < 0.001) and nutritious value (p-value < 0.001) of both beverages, the cashew nut beverage being perceived as more nutritious and healthier than the soya beverage. Consumers’ different characteristics with respect to their interest in healthy eating (high and low) and food neophobia (neophiliacs and neophobics) did not have any influence on the beverages’ acceptance, as well as on the perception of healthy food and nutritious value.

Originality/value

This work compares consumers’ acceptance and perception regarding nutritional value and healthiness with relation a totally unique product in the Brazilian market, and in the world, a new functional beverage made from cashew nuts, with a soya-milk beverage. Until this moment, there are no studies comparing consumer acceptance and perception of products based on hydrosoluble extract-base added with fruit juice which evaluate the influence of behavioural and personality characteristics of consumers in their perception and acceptance towards these products.
