title: Effects of carbon dioxide and ozone treatments on the volatile composition and sensory quality of dry-cured ham.
abstract: Randomized complete block designs with 3 replications were utilized to evaluate the effects of carbon dioxide (CO(2)) (0% at 96 h, 60% at 48 h, and 60% at 96 h) and ozone (O(3)) (0 and 175 ppm for 48 h) on the volatile flavor compound concentrations in dry-cured ham. Minimal differences existed in the presence and concentration of aroma active compounds in both CO(2) and O(3) fumigated hams but phenols were slightly more prevalent (P < 0.05) in the CO(2) treatments and oxidation compounds were slightly elevated (P < 0.05) in the ozone treated samples when compared to the control. Triangle tests (n = 54 and 56) indicated that consumers could not discern (P > 0.75) between the control hams and the hams that were fumigated with CO(2) and O(3), respectively. This study revealed that there were minimal aroma/flavor differences among the ham treatments between 0 and 60% CO(2) for 96 h; and also between 0 and 175 ppm O(3).
