Colour parameters of DFD beef meat.

摘要

The aim of our study was to evaluate the colour of DFD and normal beef meat by CIELAB system and to analyse haeme pigments in Musculus gluteus medius. Colour parameters (L*, a*, b*) and haeme pigments were measured in DFD beef (pH over 6.2) and normal beef meat (pH<5.8). Colour parameters and values of pH were measured during 48 hours. We found significant differences (P<0.001) between DFD and normal beef meat in all pH values and all colour parameters during 48 hours. DFD beef meat had the lowest L* value, a* value and b* value, but the highest pH value.
