Cholesterol content in meat of some poultry and fish species as influenced by live weight and total lipid content.
Total cholesterol content in 24 fillets (F) of males and females of common carp, 35 samples of male chicken breast meat (BM) and thigh meat (TM), and 48 samples of male turkey BM and TM, respectively, was determined by high-performance liquid chromatography after total lipid (TL) extraction using n-hexane/2-propanol mixture. Cholesterol content in male carp fillets (77.6 mg/100 g) was higher (P < 0.001) in comparison with females (69.4 mg/100 g). Irrespective of the sex differences, cholesterol content increased (P < 0.01) in the sequence chicken BM (53.0 mg/100 g) = turkey BM (53.0) < turkey TM (61.5) < carp F (73.5) < chicken TM (82.9 mg/100 g). Cholesterol content in chicken TM decreased (P < 0.05) with increasing live weight reached at the age of 43 days, but did not change (P > 0.05) in other tested tissues. Cholesterol concentration in TL of all five tested tissues within three animal species decreased sharply (P < 0.001) with increasing TL content reached in a given tissue at the fixed age. It follows from the results of the study that a two hundred gram portion of carp F and chicken TM without skin represents 49 and 55% of the upper limit of daily cholesterol intake, respectively.
