Marine products and co-products


The abundant and nutrient-rich biomass offers a wide range of potential applications, including antimicrobial properties for food (peptides derived from snow crab co-products) and the ability to modulate glycemic response (bioactive derivatives from brown algae).

A sea of
compounds of interest

Fishing, aquaculture, and seafood processing constitute an economically significant sector in Quebec. This resource, along with the by-products from its processing, represents a vast reservoir of compounds of interest for the development of functional ingredients and foods. The research conducted by INAF and its partners in this field encompasses the characterization of active biomolecules to the validation of their health effects through clinical nutritional studies. Through sustainable production processes, numerous marine extracts can be evaluated to demonstrate their potential for human health and explore potential applications in food production, nutrition, pharmacology, and cosmetology.

Here are a few
project examples

CuisiAlg Project

Edible Seaweed and Health: Quality Biomarkers to Enhance Consumer Acceptance

Objective: Studying the perception and consumption of Quebec seaweeds

The project aims to scientifically study the health benefits of Quebec seaweeds and assess their acceptability among consumers.

Neuronalg Project

The Neuronalg Project aims to identify novel biomolecules present in seaweeds that have a positive impact on the brain, inflammation, and intestinal microbiota. Ongoing research is focused on enhancing the extraction processes of these molecules and demonstrating their health benefits.

This collaborative initiative brings together academic and industry partners from France and Quebec, including Université Laval, Université de Bordeaux, Université La Rochelle, and Merinov.
