W pracy podjęto próbę wzbogacenia wybranych serów twarogowych i topionych w wielonienasycone kwasy tłuszczowe omega-3 dodatkiem preparatu oleju rybiego i oceniono wpływ zastosowanego poziomu dodatku na ogólną jakość sensoryczną, badanych produktów. Wykazano, że wybrane do badań sery nadają się do wzbogacania olejem rybim w różnym stopniu.

The results of this work indicate that the flayour-related feasibility of enriching studied cheeses by adding fish oil varies with cheese types. Processed cheeses characterised by higher fat content may be added higher levels of fish oil. Strong-flavoured cheeses, such as garlic-flavoured processed cheese, effectively mask the savour of the fish oil. The highest levels of the enrichment were selected for the spreadable quarks and processed cheeses, and the usual 4-week storage period only slightly affected their savour. Spreadable quarks enriched with the omega-3 acids at 15 g/kg and processed cheeses enriched with those acids at 40 g/kg may constitute a major dietary source of those acids. A daily portion 30 g of enriched cottage or processed cheeses evaluated during the study may provide 150 to 400 mg of Jong-chain omega-3 polyunsaturated fatty (EPA and DHA) acids, satisfying the minimum daily dietary requirement for those acids.
