Edible Seaweeds and Health: Quality Biomarkers to Support Consumer Acceptance

Seaweeds have been part of the diet of Asian countries for thousands of years, but consumption by Quebecers remains unfamiliar. Because of their rich nutrients content and unique bioactive compounds, seaweeds have a great dietary potential. The overall objective of the project is to determine the potential for sustainable local exploitation of St. Lawrence seaweeds by assessing their quality under growing conditions and following processing, and to use them as a basis for culinary innovations for both industry and consumers. Our specific objectives are as follows: 1. To assess the impact of environmental factors on the specific profile of biomarkers of nutritional quality and health potential of harvested or cultivated seaweed; 2. To determine the impact of processing on the profile of biomarkers of nutritional quality and health potential of harvested and cultivated seaweed; 3. To study changes in dietary attitudes and behaviours through a culinary workshop promoting the acceptance of seaweeds and their appropriation as an ingredient by consumers. The application for ethical approval and this trial registration applies only to Specific Objective 3.
