Abstrakt: Background: Many consumers have a high salt intake and bread is a primary source because of its high rate of consumption. The inclusion of seaweeds has been proposed as an ingredient that could help reduce the salt content of food products. As such, the present study aimed to evaluate whether the amount of salt in bread could be reduced and the change in sensory properties be mitigated by the inclusion of brown seaweed. There were two different sensory trials conducted. In the first trial, participants (n = 102) evaluated bread made with brown seaweed (4% substitution for flour) with reduced amounts of salt (10%, 20%, 30%, 40% and 50%). The second trial asked participants (n = 98) to evaluate the control bread and the 20% salt-reduced bread in blinded and informed conditions. In both sensory trials, the breads samples were assessed using hedonic scales, just-about-right scales, and check-all-that-apply.
Results: The results showed that the 10% and 20% salt-reduced breads were acceptable and associated with being soft, chewy and having no aftertaste. The other breads were associated with a dense, dry and strong aftertaste, along with not being salty enough for the consumers. When the breads were evaluated in informed conditions, the salt reduction label had a negative impact on the consumers' liking.
Conclusion: The research emphasizes that salt-reduced labels influence consumers' sensory perception. © 2023 The Authors. Journal of The Science of Food and Agriculture published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.
