Bioactive molecules from marine animal biomasses

Semester 3

The objective is to make the student ready to develop and propose a comprehensive approach for enhancing the value of fisheries and aquaculture products from animal origin (including by-products) for the development of new added-value molecules and ingredients, intended for food, feed, aquaculture, cosmetics, … Marine biotechnologies are targeting niche markets by offering products with low volumes and high added-values, and also mass markets like bio-sourced polymers.

Course Contents

Introduction: Global overview of how enhancing the value of fisheries and aquaculture products from animal origin: definitions, resources, markets, notion of value chain, current trends, and examples of innovation in Norway.
Chapter 1: Concentrates and isolates of proteins: conventional methods, Ph-shift, pulps.
Chapter 2: Gelatines et collagens: general properties, specificities of marine collagens, impact of process on techno functional properties. Niche and mass applications of gelatines. Innovative uses in nutraceutics, nutri-cosmetics et biomaterials (tissue engineering, …)
Chapter 3: Enzymes in industrial processes: 3.1. Fish protein hydrolysates (FPH) with functional properties: pH-stat method, characterisation of peptidic populations, choice of enzymes for FPH. 3.2 Use of enzymes for the controlled destructuration of complex matrices: application to microalgae.
Chapter 4: Peptides exhibiting biological activities: definitions, examples in food, feed, nutraceutical, cosmetics,
Chapter 5: Biopolymers (chitin and chitosan, chondroitin sulphate, hyaluronic acid: general characteristics, extraction process, properties et example of uses.
Chapter 6: Marine lipids: structures and functions: PUFA and phospholipids
