PRODUCING A NOVEL CANOLA PROTEIN CONCENTRATE USING SOLID STATE FERMENTATION TECHNIQUE FOR RAINBOW TROUT Oncorhynchus mykiss

One of the main challenges for producing canola protein concentrate is the simultaneous concentration of nutrients and anti-nutritional factors (ANFs) in the final products. Fermentation will introduce new fermented products to aquafeed industry in the near future through reduced peptide size of proteins, increased nutrient digestibility, reduced feed sensitivity, growth promoter compounds (essential amino acids and vitamins) and immuno-stimulants. Successful use of Neurospora sitophila has been reported in the production of functional foods from soybean seed, coconut and peanut meals. However, there is no report regarding the production of canola protein concentrate using the solid fermentation technique in aquaculture nutrition. The fermentation efficiency can be monitored indirectly by measuring chemical composition such as dry matter, crude protein and glucosamine contents of the final products.
