Fatty acid compositions of frequently consumed foods in Turkey were analyzed by capillary gas chromatography with particular emphasis on trans fatty acids. The survey was carried out on 134 samples that were categorized as meat products, chocolates, bakery products and others. The meat products except chicken-based foods have trans fatty acids, arising as a result of ruminant activity, with an average content of 1.45 g/100 g fatty acids. The conjugated linoleic acid content of meat and chicken doner kebabs were found higher than other meat products. Chocolate samples contained trans fatty acids less than 0.17 g/100 g fatty acids, with the exceptional national product of chocolate bars and hazelnut cocoa cream (2.03 and 3.68 g/100 g fatty acids, respectively). Bakery products have the highest trans fatty acid contents and ranged from 0.99 to 17.77 g/100 g fatty acids. The average trans fatty acid contents of infant formula and ice-cream, which are milk-based products, were 0.79 and 1.50 g/100 g fatty acids, respectively. Among the analyzed foods, it was found that coffee whitener and powdered whipped topping had the highest saturated fatty acid contents, with an average content of 98.71 g/100 g fatty acids.
采用毛细管气相色谱法对土耳其常见食用食品的脂肪酸组成进行了分析，特别关注了反式脂肪酸。该调查针对134个样本展开，这些样本分为肉类产品、巧克力、烘焙产品及其他类别。除鸡肉类食品外的肉类产品因反刍动物活动而含有反式脂肪酸，平均含量为1.45克/100克脂肪酸。发现肉夹馍和鸡肉烤肉串中的共轭亚油酸含量高于其他肉类产品。巧克力样本中反式脂肪酸含量低于0.17克/100克脂肪酸，但巧克力棒和榛子可可奶油这两种国产特色产品除外（分别为2.03克/100克脂肪酸和3.68克/100克脂肪酸）。烘焙产品的反式脂肪酸含量最高，范围在0.99至17.77克/100克脂肪酸之间。以牛奶为基础的产品婴儿配方奶粉和冰淇淋的平均反式脂肪酸含量分别为0.79克/100克脂肪酸和1.50克/100克脂肪酸。在所分析食品中，发现咖啡增白剂和粉状鲜奶油的饱和脂肪酸含量最高，平均含量为98.71克/100克脂肪酸。
