Production of fish sauce from Icelandic seafood with useful fermentation / Fish Sauce produced by useful fermentation

Fish sauce is a clear brownish liquid that has a characteristic smell and taste. Fish sauce can be produced by fermenting fish puree and salt with or without added excipients. Fish sauce is often used as a flavoring in cooking. Fish sauce was produced using 3 methods from different raw materials such as by-products of fillet processing as well as pelagic fish. Specially treated Icelandic barley was also tested for fish sauce production. Samples from fish sauces were evaluated in sensory evaluation, ie. taste, smell, color and turbidity. The chemical content, amino acid composition and bioactivity of the samples were measured. The yield of fish sauce production was assessed. Business analysis for fish sauce was performed. The results of the project indicate that it has been possible to produce fish sauce that can be compared to sauces that are sold widely.

Fish sauce is a brownish liquid with distinctive odor and flavor. Fish sauce can be produced with fermentation w./wo added enzymes. Fish sauce is commonly used as a condiment. Fish sauce was produced by 3 methods from various raw materials eg by ‐ products of fillet production and pelagic species. Koji developed from Icelandic barley was used in trials of fish sauce preparation. Samples of fish sauces went through sensory analyzes. Chemical content, free amino acid proportion and bioactivity of the samples were measured. Yield in fish sauce preparation was estimated and business plan was drafted. Results indicate that preparation of fish sauce similar to commonly traded products was successful.
