ABSTRACT
The demand of consumers from around the world for natural, nutritional and palatable pork meat is increasing with time. This study analyzed macro (Ca, K, Mg, Na, P), micro (Fe, Zn, Cr, Mn, Ni, Cu, Se, Sr, Cs), trace (Li, Be, V, Co, Ga, Ba, U), and toxic trace (As, Cd, TI, and Pb) elements of pork meat from conventional and animal welfare farms in South Korea. Among the elements analyzed by inductively coupled plasma-optical emission, and mass spectrometric (ICP-OES, ICP-MS) techniques, K, Fe, Mn, and Ni content were higher in animal welfare pork meat. The trace and toxic trace elements content were lower than the standard values. The principal component and linear discriminant analyses (PCA, LDA) explained the highest variance (99.82%, 99.00%) of the group based on toxic elements. These findings can thus be used to evaluate animal welfare and conventional farms pork meat quality in South Korea as well as worldwide.
