Tasting seaweed : A scoping review of methodologies used in sensory evaluation of seaweeds

A scoping review of methodologies used in sensory evaluation of seaweeds BackgroundSensory analyses are important tools in developing healthy and sustainable foods that correspond to consumers’ wants and needs. Seaweeds have been described as a highly sustainable future food, particularly for the Western world, where it is not commonly consumed. Therefore, sensory evaluations are needed to pave the way for new seaweed products with high consumer acceptance. AimThe aim of this study is to describe available scientific knowledge on sensory evaluation of seaweeds, focusing specifically on methodological perspectives. MethodFor this scoping review, three databases (Scopus, Web of Science, and Pubmed) were searched, using a defined search term that yielded 1,004 unique records. After screening and applying predefined criteria, 92 records remained. The information extracted from the papers included sensory methodology, number of participants, proportion of seaweed included in the samples and sample preparation. ResultsAnalytical and affective analyses were identified, including trained, and untrained, and naïve panelists. These were published in scientific journals, of which only a small proportion were specialized in sensory and consumer science. In this review, different methodologies applied were evaluated in relation to the stated aim of the included studies. Preliminary findings identified differences in the sensory methodology of the included studies, e.g., sample preparation, sample sizes, hedonic- and intensity scales, and training of panels. DiscussionOur initial review suggests that there could be significant value in developing standardized guidelines concerning the methodology employed in sensory studies of seaweed. This consideration becomes particularly pertinent when contributing articles to journals that may not specialize in sensory-focused research. By aligning methodologies more closely with established standards, we can enhance the clarity, relevan
