Abstract: | The evolution of biochemical, instrumental colour and texture, sensory parameters and consumer acceptability of 12-month dry-cured hams maintained up to 26 months under “bodega” conditions (18 °C, 75% relative humidity) was assessed, in order to investigate the influence of extended ripening on their sensory characteristics and acceptability. Results demonstrated that ham acceptability showed no significant differences (p > 0.05) from 12 to 22 months, while it decreased significantly (p < 0.05) until 26 months. Principal component analysis of all data brought about a comprehensive explanation of the biochemical, instrumental and sensory parameters involved in the acceptability decrease. In fact, high pastiness and adhesiveness values, as measured by both sensory and instrumental methods, appeared to be most related to decreasing acceptability. Those attributes were the result of an excessive proteolysis, as revealed by biochemical maturation indices. |
