Congratulations, Dr. Rafiq
MSc Rafiq Ahmad today successfully defended his thesis titled Thermal and rheological properties of fish feed protein ingredients. The project has been run at Nofima. Although introducing soy protein concentrates to fish feed is desirable from a supply point of view, it does introduce problems to the extrusion process necessary to make feed pellets. Rather than plasticizing the mixture by addition of water, which is energy costly in the subsequent drying step, Refiq has explored the use of other protein additives rich also in free amino acids, to facilitate the extrusion step.
