Cholesterol content in meat of some Cyprinidae

Abstract

The aim of this paper was to examine cholesterol content in meat of five Cyprinidae species: white bream (Bllica bjoerkna L.), carp bream (Abramis brama L.), baltic vimba (Vimba vimba carinata Pallas), zope (Abramis balerus L.) and crucian carp (Carassius carassius gibelio Bloch) from the river Danube. Cholesterol content was examined in the function of season factor and individual weight. Cholesterol concentration in meat of white bream carp bream, baltic vimba, zope and crucian carp is on average level below 20 mg/100 g of meat, which makes meat of these fish species nutritively very valuable. Cholesterol content is variable during the season. Its concentration in meat and in lipids is lowest during spring, during summer it increases and during autumn decreases, except in meat of white bream. Body weight has influence on cholesterol content when its concentration is expressed as % of cholesterol in lipids. Its content in lipids decreases with increasing of individual weight, except in meat of carp bream.

Jedan od najznačajnijih faktora rizika koji dovodi do razvoja ateroskleroze i bolesti srca i krvnih sudova je povišen nivo holesterola u krvi. Stoga je cilj ovog rada bio da se ispita sadržaj holesterola u mesu pet vrsta Ciprinida poreklom iz reke Dunav, u funkciji sezonskog faktora i mase jedinki. Sadržaj holesterola u mesu, svih ispitivanih vrsta riba, je na niskom nivou. Njegova prosečna vrednost tokom perioda proleće-jesen kreće se od 14.85 mg/100g u mesu špicera, do 31.40 mg/100g u mesu krupatice. Sadržaj holesterola, u mesu deverike, plavonosa, špicera i babuške je ispod 20 mg/100g mesa, što su znatno niže vrednosti no u mesu toplokrvnih životinja. Koncentracija holesterola u mesu i u masti najmanja je tokom proleća, tokom leta se povećava, a u toku jeseni smanjuje, osim u mesu krupatice. Masa trupa utiče na sadržaj holesterola u slučaju kada je njegova koncentracija iskazana kao % holesterola u masti. Njegov sadržaj u masti smanjuje se sa povećanjem mase jedinki, osim u mesu deverike.
