Evolution of volatile aldehydes in Iberian ham matured under different processing conditions

To evaluate the influence of the Iberian ham processing conditions in the e volution of Volatile aldehydes, 35 hams were processed in two plants follow ing different conditions of relative humidity and temperature. For this, fr ee fatty acids, peroxide values and volatile aldehydes were quantified in t he hams. The highest increases in free fatty acids were noted during the dr ying stage in both processing plants. The drying period also revealed the g reatest increase in peroxide values, where the highest values were in those hams processed at higher temperatures. The temperature during post-salting and drying had a marked influence on the formation of volatile aldehydes, being responsible for the differences in volatile compounds of matured hams .
