Volatile compounds of dry hams from Iberian pigs

Area of Science:

• Food Science
• Animal Science
• Analytical Chemistry

Background:

• Iberian pigs are renowned for their high-quality dry-cured ham.
• Diet significantly influences the flavor profile of dry-cured ham.
• Understanding volatile compounds is key to characterizing ham quality.

Purpose of the Study:

• To identify and compare volatile compounds in dry-cured hams from Iberian pigs fed different diets.
• To determine the impact of diet on the chemical composition of ham volatiles.

Main Methods:

• Headspace volatile analysis using gas chromatography-mass spectrometry (GC-MS).
• Identification of over 64 volatile compounds across three dietary groups.
• Statistical analysis to determine significant differences between batches.

Main Results:

• Sixty-four volatile compounds were identified, including aldehydes, alcohols, and fatty acids.
• Significant quantitative differences in volatile compounds were observed between dietary groups, particularly 'montanera' and 'pienso'.
• No qualitative differences in volatile compounds were found between the ham batches.

Conclusions:

• Diet is a major factor influencing the quantitative profile of volatile compounds in Iberian dry-cured ham.
• 'Montanera' and 'pienso' diets result in distinct volatile compound profiles.
• Further research can leverage these findings to optimize ham production for specific flavor characteristics.
