Abstract from the study
The aim of the project was to increase the utilization and value of raw materials and the convenience of consumers through the development of prepared foods from fish proteins.

It was investigated how isolated fish proteins can be processed and used as additives in prepared foods. Antifreeze had to be added to wet isolated haddock protein before freezing into blocks to ensure its stability during freezing. Oxidation before and during the processing of isolated proteins from saithe led to extensive development in dried powder so that it could not be used for product development. Drying of saithe washes rinsed and purified from water (surimi) was also studied. It turned out to be possible to produce a powder that was suitable for product development by both freeze-drying and spray-drying. 7% of lyophilized saithe powder could be added to extruded cornmeal. A so-called chop mix with 30% saithe powder was developed. Finally, an attempt was made to add lyophilized saithe powder to Iranian food. There was no difference in taste, appearance and texture of ice cream with 0, 3 or 5% saithe powder after 2 months of storage at -18 ° C. After that, there were changes in taste, smell and texture. Scientific and technical information from the project is important and constructive both for ongoing research on the utilization of fish proteins and for companies that are interested in developing prepared foods and snacks with added fish proteins. This would increase the value of underutilized raw materials and at the same time be one way to increase fish consumption in countries or areas where there are no traditions for cooking fresh or frozen fish.

The doctoral dissertation is based on eight scientific articles, two of which have already been published in an international scientific journal and two others have been approved.

The United Nations University School of Fisheries awarded a scholarship to Gholam Reza Shaviklo. Matís ohf, Iceoprotein hf, Iran Fisheries Research Organization (IFRO) and Iran Fisheries Organization (SHILAT) in Tehran, Iran, SIPA Co., Qazvin, Iran, Iran Fish Processing Research Center (Anzali, Iran), provided its research facilities. The research in the project belonged to the projects Propephealth in SEAFOODplus (project no. FP6-016333-2) funded by the 6th Framework Program of the European Union and Health Products from Fish which is funded by the Technology Development Fund.
