Improved processing of capelin roes

The processing of capelin roe is largely based on research and development that took place between 1972 and 1982. The weakness of the processing process has been the drying of the roe, where roe is left in pots for up to 20 hours where excess water is allowed to leak. . The drying method disrupts the continuity of processing, is costly and increases the risk of microbial growth in the product. The report discusses the effect of processing factors on the chemical and physical properties of capelin roe, as well as the results of experiments with continuous drying during the processing of capelin roe.

Current processing technique of Capelin roes is based on research and development carried out in 1972 to 1982. The weakness of the current process is the drying procedure where the roes are allowed to stand for up to 20 hours while excess water drains off to desirable level. This drying process disturbs the continuity of the process, is costly and increases the risk of bacteria growth. This report discusses the influence of various processing steps on the physical and chemical composition of the Capelin roes and results from experiments with continuous drying procedures in the processing of Capelin roes.

In recent years and decades, various measurements and research on capelin roe in Iceland have been carried out at Matís ohf / Rannsóknastofnun fiskiðnaðarins. This is primarily a study of microorganisms, egg filling and water content. The report will cover microbial research carried out during the 1984 season, microbiological measurements in the period 2000-2008 and measurements of water content and egg filling 1984-2008.

In recent years and decades various studies and measurements have been carried out on capelin roes in Iceland at Matís ohf / Icelandic Fisheries Laboratories. They mainly include studies on microorganisms, roe-fill and water content. In this report, microbial studies on microorganisms from the capelin season 1984 are presented along with microbial measurements carried out during 2000-2008 and measurements of roe-fill and water content 1984- 2008.
