Use of vital wheat gluten in aquaculture feeds Emmanuelle Apper-Bossard* , Aurélien Feneuil, Anne Wagner and Frédérique Respondek Summary In aquaculture, when alternative protein sources of Fish Meal (FM) in diets are investigated, Plant Proteins (PP) can be used. Among them, Vital Wheat Gluten (VWG) is a proteinaceous material obtained from wheat after starch extraction. “It is mainly composed of two types of proteins, gliadins and glutenins, which confer specific visco-elasticity that’s to say ability to form a network providing suitable binding. This will lead to specific technological properties that are notably relevant to extruded feeds”. Besides these properties, VWG is a high-protein ingredient with an interesting amino-acid profile. Whereas it is rather low in lysine, it contains more sulfur amino acids than other PP sources and it is high in glutamine, which is known to improve gut health and modulate immunity. VWG is a protein source with one of the highest nitrogen digestib Less
