MRI-based analysis of feeding background effect on fresh Iberian ham

► This work describes the MRI analysis of hams from pigs fattened with different diets. ► It also studies the physical-chemical composition of the Iberian hams. ► MRI-bases analysis can be a useful tool for discerning hams as a function of pig diet. ► Data from MRI analysis and physical-chemical composition are highly correlated. ► Obtained results in this paper are of importance in terms of meat and meat products.
