Abstract

A total of 6700 veal calves were used to compare the ability of chromameter CR300 in measuring the veal meat colour on-line at slaughterhouse and to develop a prediction equation of colour score based on relationship between instrumental and visual assessments. A total of 5000 carcasses were used to develop equation of prediction while 1700 were used to test it. The meat colour was assessed subjectively in 3 different slaughterhouses by the slaughterhouse's judges 10h post mortem and objectively by chromameter CR300 45 post mortem on the Rectus abdominis. The prediction equation classified correctly 79% of carcasses and was characterized by an R-2 of 78%. Furthermore it has to be underlined that the chroma contributes to the total R-2 with a 0.21 partial R-2. This data confirmed that chromameter CR300 can be used on-line to measure objectively veal meat colour at the end of the slaughter line
