摘要
We describe a method based on isotope analysis (delta(13)C) for characterization and differentiation of Iberian pork meat as a function of the diet of the animal. Using adipose tissue, it is possible to classify unknown samples in group of animals designated "acorn-fed", "recebo = mixed-fed" and "feed raised" according the delta(13)C value obtained, from the calibration straight line of y = -22.12-0.35x, with a correlation coefficient r = 0.982 and s = 0.1%; where y = delta(13)C and x = arrobas of acorn and range forage received by the animals during the fattening period. Stress should be placed on the economic and industrial importance of Iberian-breed swine because the market prices of Iberian swine products depends on the classification of the animals according to the type of feeding regimen which they are subjected to.
