Recently, eight IFL reports, which had been closed temporarily after work on the relevant projects was completed, were opened. The reports are from the years 2003 and 2005.
The reports from 2003 are all from a project that began in 2000 and ended in 2003. The project's working title was Light salting, stability and utilization of frozen products and the aim was to examine how water retention, chemical composition and texture of fish flesh could be controlled by light salting.
It was investigated whether it was possible to produce juicier products than was possible with conventional pre-freezing processing. The effects of the use of salt, phosphates and processed proteins in brine on the aforementioned factors were evaluated and information on regulations and market attitudes related to the management of the chemical composition of fish products was collected. The reports now appearing from this project are number 07-03; 10-03; 12-03 and 13-03. One report from the aforementioned project was published in 2003, report no. 09-03.
Of the reports from 2005 that have now been opened, three are from the same project that began in 2004 and ended last year. Its job title was Production of shaped fish pieces and gel blocks from cuttings and marlin, and aimed to develop a processing process to produce shaped fish pieces with fish glue. The idea was to use less expensive by-products and fish species in the fish paste production, such as cuttings, marlin and blue whiting.
Production of shaped fish fillets began in Iceland in the 1980s, and at first it was mainly raw materials that had been cut into small pieces and then molded into cakes or other shapes with stamps. In this way, cuttings from fillet processing were used directly in bread products where the natural appearance of fish pieces could be imitated. Higher prices have been obtained for such products than when the raw material has been placed in a block. Blocks made from boneless and peeled fillets of whitefish, however, have been produced for more than 50 years and are still an important raw material in the further processing of fish products in North America and Western Europe.
Rehabilitation in the fishing industry uses pressure that disrupts normal muscle structure and purees the fish. In the aforementioned project, one of the main goals was to use the fish glue to be able to reduce the pressure during shaping and maintain / create a normal muscle structure in the product, which is a novelty. The three reports that have now been opened are numbered 19 to 21 in 2005.
Finally, we can mention report no. 24-05 which bears the title Protein in wastewater Preliminary study of quantities and properties and its aim was to obtain basic information on the amount and type of proteins in wastewater in order to examine whether they could possibly be used in some way for human consumption.
