摘要

The aim of this study was to examine the relationship between meat quality parameters, intramuscular fatty acid composition, instrumental texture and sensory attributes on pork. The animals were fed a basal diet (control diet) supplemented with different fats: animal fat (1%; 3%), soyabean oil (1%) and calcium soaps of palm oil fatty acids (1%). A principal component analysis (PCA) was performed with the variables measured in Longissimus thoracis et lumborum muscle. The PCA explained 76.33 % of the variability of the results within the first two axes. The first PC (58.43 %) was characterized by the major saturated (SFA) and monounsaturated (MUFA) fatty acids, tenderness and fat flavour. These variables were negatively correlated with the polyunsaturated acids (PUFA) and PUFA/SFA ratio, lying near the first PC on the opposite side. IMF content and juiciness were negatively correlated with WBSF values. Each quadrant in the biplot discriminated against one of the type of added fat. Control and animal fat diets were on the left side of the graph, close to the variables SFA, MUFA and IMF, whereas soyabean oil diet was situated on the right side of the graph, where the PUFA were grouped.
