Isolation, purification and research into antihypertensive peptides from fish proteins

Studies of peptides derived from various food proteins have found peptides with antihypertensive properties. Icelandic fish proteins could potentially become an important source of such peptides that could be used for the development of valuable fish products and health food. The aim of the project is to study this activity in fish peptides and to isolate, purify and define peptides with antihypertensive effects. The report reports the first results on the isolation of fish protein peptides and measurements of their antihypertensive effects.

Various processed food proteins have been reported to include peptides with possible antihypertensive effect. Fish proteins are a potential source for such blood pressure-lowering peptides that might be used to develop valuable fish products and nutraceuticals. The aim of this project is to study the activity of fish proteins and isolate, clarify and define peptides with antihypertensive properties. The report presents the first results regarding the isolation of fish protein peptides and their bioactive properties as ACE inhibitors.
