Evaluation of Egg Yolk Colour

Popis výsledku v původním jazyce

We compare visual evaluation of yolk colour estimated by the usual method applying La Roche scale with spectrophotometric determination of beta-carotene by AOAC method, and by new rapid analyser iCheck (TM) Egg photometer (BioAnalyt). The eggs under consideration were purchased on a current Czech market. The eggs originated from various countries and various types of breeding including some specialities. The yolk colour varied between the values of 4-13 of La Roche scale. The carotenoid content expressed as beta-carotene measured by AOAC method varied between 11-87 mg/kg. The carotenoid content expressed as beta-carotene measured with the analyser iCheck (TM) Egg photometer was lower and varied between 7.5-68.5 mg/kg. The correlation between the colourhue measured visually and the carotenoid content was not proved. Slovak eggs from cages which contained 28.3 mg carotenoids in 1 kg of yolk had the darkest yolks (value 13), Czech bio eggs which contained 20.2 mg carotenoids in 1 kg of y
