| The content of insulin-like growth factor 1 (IGF-1) in bovine milk in México is unknown, and high levels could increase the health risk for adult people who ingest milk. The aim of this study was to determine the level of IGF-1 and its relationship with fat content using liquid chromatography with ion trap as a mass detector in milk marketed in Durango, México. During 18 months we analyzed, three times, six lots chosen randomly of whole, reduced-fat, and low-fat milk of three brands. Each sample was pre-treated using cut-off membranes, digested with trypsin, and subjected to liquid chromatography-mass spectrometry. There was a significant difference in the mean concentration of IGF-1 between the brands and types of milk analyzed (Chi square=34.66;... |
