Assessment of Cholesterol Contents in Egg Yolk and Yoghurt Samples.

Abstract

Ten yoghmt samples obtained from shops and supennarkets in Minna metropolis were analysed for cholesterol content using llca's reagent based on Lieberman n - Bu rchard reactio n . Except for samples G :md H with cholesterol val ues signi ficantl y ( P<0.05) higher than N A FDAC concentration range (0.55 - 3.50 mg Cfi,). all other samples had values w i th in the N A FDAC concentration l i mit. Five pai rs of bird s' eggs (local and hybrid), namely : Col/ us do111es1irns, M e/leag ris golloporo, A 11as platv/1_rnclw. N11111id 111el/ eogris and Colu111ba livio were al so obta i ned from M i n na Cent.ml Market and were analysed for cholesterol in the yol k usi ng spectrophotometer at absorhance of 650 nm. Cholesterol concentration of lhe yolk of local breed Col/us domesticus was significantl y (P<0.05) high (1 1.80 ::!: 0.46 mg/ml ) compared to other birds. The hyb1id of Colu111ba Livia had the lowest concentration (5.65 ± 0.44 mg/ml) of cholesterol. Based on the values obtained ' from these works, eight of the yoghu11 samples (except samples G and H) are considered safe for consumpti on, while Columba Livia considered the most prefeITed bi.rd safe for consumption.
