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.

For recruitment purposes, adults interested in cooking and consuming Quebec seaweeds will be randomly assigned to an experimental group (n=16 x 3 groups, ingredients, recipes and a culinary workshop) or a control group (n=16 x 3 groups, ingredients and recipes). Online questionnaires will be administered via the secure platform of INAF (FANI) at the beginning and the end of the study.

Inclusion Criteria:

• be interested in cooking and consuming Quebec seaweeds in various forms
• be available to fill out online questionnaires and perhaps participate in a culinary workshop in Quebec City

Exclusion Criteria:

• have allergies and dietary restrictions
