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

Popis výsledku v původním jazyce

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.
