ABSTRACT=Brewer’s spent grain (BSG) has been commonly considered as only a waste product, but recent research in its composition has shown that it can be a functional ingredient. The aim of this study was to analyse consumers’ attitudes towards different BSG-added food products under informed conditions. BSG-enriched bread, pasta and chocolate milk were studied exploring two major aspects. Firstly, eye-tracking technology was used to reveal the effect of different food labels in consumers’ attention and purchase intention. Information on sustainability and on BSG varied among the labels under analysis. The best consumers’ response occurred when the label displayed: sustainability logo, fibre source claim and BSG description. The phrase “Malted Barley” as an appellation of BSG was also analysed, although it did not produce a significant effect on consumers. Secondly, consumers’ response to fibre-enriched products and regular products, under informed condition, were assayed through sensory evaluations. For bread and chocolate milk samples, no significant difference was found in acceptability between the regular and fibre-enriched version. For pasta, on the other hand, consumers expressed a significant preference in terms of overall liking towards the fibre-enriched version. BSG-enriched products were accepted as much as the regular ones when information was provided, confirming the importance of the fibre source claim and sustainability claims.
