ABSTRACT
The aim of this study was to establish sensory and nutritionally acceptable enrichment level of low calories spreadable fats (soft margarine and mix of butter and vegetable oil) with omega-3 eicosapenta- and docosahexaenoic acids (EPA, DHA) by addition of fish oil preparations (ROPUFA - 30% EPA, DHA and MARITEX - 10%), and evaluation of enriched spreads stability (sensory and chemical) during storage. It was shown that tested spreadable fats might be enriched up to 1% EPA, DHA (i.e. 3% ROPUFA, 8% MARITEX), that had no significant influence on sensory acceptability. Both used fish oils exerted similar influence on fats quality. Enriched mix of butter and vegetable oil and margarine may be stored up to 3 and 9 weeks respectively without significant decrease of quality. Peroxide value and acid numbers were not much affected by enrichment and storage. Daily portion (25-30 g/day) of spreadable fats enriched on level established in the study may provide 0.2-0.3 g EPA, DHA significantly increasing long chain omega-3s amount in the diet above those eaten normally.
