Abstract

Trans fatty acid content in fat from domestic cow and goat milk was determined by conducting capillary GLC and silver-ion TLC in conjunction on fatty acid propyl esters.<BR>1) In sixty-eight commercial cow milk samples purchased from August to October 1994, mean t-C18 : 1 acid was 3.2% (range : 2.1% to 4.9%) of total fatty acids, this being in good agreement with data reported for French butter. Total trans fatty acid content (including t-C16 : 1, C18 : 2 and C18 : 3) varied from 2.7 and 7.5% (mean 4.5%).<BR>No species (Holstein, Jersey or Guernsey) or regional differences in trans fatty acid content could be detected.<BR>2) In five commercial goat milk samples purchased from April to May 1995, mean total trans fatty acid was 5.6% (range : 4.4% to 6.3%) of total fatty acids.<BR>3) As for seasonal variation in cow milk from dairy farm from November 1994 to October 1995, total trans fatty acid content was highest (4.8%) in milk during December to February and lowest (3.3%) during June to August. These values were signiticantly lower than those in European countries, indicating the differences in feed stuffs.
