Abstract

The effects of pig breed (Large White and Landrace) in combination with muscle type (M. semimembranosus and M. longissimus dorsi) on T45min, T24h, pH45min, pH24h, colour (CIEL*a*b* values), water-holding capacity (filter paper press method: ratio of the area of pressed meat film – M and the wet area on the filter paper – T; M/T value) and moisture, protein, total fat and total ash content were investigated. Interaction effect between breed and muscle was not found (p>0.05) for any parameter. The T45min, T24h, pH45min, and M/T value were influenced by the muscle, whereas T24h was also influenced by the breed. The pH45min was higher (p<0.01) and water-holding capacity was better (p<0.001) in M. semimembranosus muscle than in M. longissimus dorsi muscle. Based on the criteria for CIEL* and M/T values, pork meat was classified into seven technological quality classes. The percentages of pale and exudative, reddish-pink and exudative, and reddish-pink and non-exudative pork were 23.5, 26.5, and 27.7%, respectively. Composition was in the characteristic range for modern lean pigs.
