Relationship between pork colour and ultimate meat quality parameters of the Czech Large White pigs

Original language description

In this study was compared two the meat quality classes of pork from Czech Large White Pigs. Samples of 144 pigs divided to the RFN (n=74), PSE (n=66) and DFD (n=4) was evaluated with pH, electrical conductivity, and drip loss in relation to colour measurements (CIELAB). RFN was represented with pHult 5.53, ECult 8.44 and drip loss 2.87 % and statistically differed from PSE group in low pHult (5.45), high electric conductivity (10.77 mS.cm-1) and high drip loss (4.13 %). Lighter meat had a progressive tendency to PSE. Mean values of pH and conductivity were in close correlation with drip loss (r = -0.29 and r = 0.38, resp.) and lightness L* (r = -0.64 and 0.47, resp.), and also between L* and drip loss (r = 0.57). Lightness L* was also near correlated(r = 0.67) with yellowness (b*), while redness a* had not so significant role.
