Comparative analysis of requirements for quality of fish oil for food and medical applications.

: Fish oil is reach natural source of vitamins А, Е, D and polyunsaturated fatty acids (PUFA) which are useful for supplementation, prophylaxis and therapy in food industry, medicine and veterinary. The analysis of regulatory documents for the quality of fish oil (based on concentration of main nutrients) leads to conclusion that content of vitamins A and D, and PUFA is controlled in medicinal preparations. With regard to fish oil for food application there is no unified approach. In particularly, content of vitamin D in food supplements with fish oil available on Russian market is not indicated by manufacturer or its concentration varies in 3-10 folds. Because of important biological functions and pharmacological activity, it is very important to have uniform standardization for vitamins and PUFA in fish oil for application in food industry and medicine. Development and unification of analytical methods became special attention for these reasons.
