Extract

The processing characteristics of pork fat are influenced by its fatty acid composition. Poor slicing quality of floppy belly bacon is caused largely by soft fat. High concentrations of saturated fatty acids (SFA) particularly stearic acid (18:0) and low concentrations of unsaturated fatty acids (USFA) mainly, linoleic (18: 2) improve firmness/hardness of fatty tissues (Wood et al, 1985). The physical properties of fat also influence the stability of emulsion-type meat products through fat loss during cooking. Losses of 0.8 from hard pork flare fat and 0.2 from soft jaw fat have been reported (Evans and Ranken, 1975). The objectives of this study were to evaluate the effects of breed, diet and slaughter weight on the fatty composition of pork fat and the quality of belly bacon and frankfurter sausage.
