Technological, chemical and physical traits of cured ham from Cinta Senese and Large White pigs, and their crosses were investigated. Hams were obtained from 29 Cinta Senese (CS), 29 Large White x Cinta Senese (LW x CS) and 12 Large White (LW) pigs, fed a commercial mixture. Sensory and chemical-physical analysis was performed on a sample-slice and on muscles (Biceps femoris - BF; Semimembranosus - SM; Semitendinosus - ST) and subcutaneous fat. CS showed the highest trimming loss and the lowest salting loss. Hams of CS pigs scored higher for fatness than those of LW pigs, LW x CS showing intermediate values. On sample-slice, CS exhibited higher firmness, redness and marbling of lean, and greater fat extension than LW, with crosses having intermediate scores. Muscle moisture was lowest in CS, while both SM and BF from LW had the highest percentage of protein and the lowest of ash. CS showed higher intramuscular fat content than LW x CS and LW. Shear force of BF was higher in CS than in LW x CS and LW. With respect to LW, CS had lower values of L* in muscles, and higher values of a* in subcutaneous fat. Subcutaneous fat of CS contained less SFA and more MUFA than LW x CS and LW.
