Dietary intake of trans fatty acids (TFA) has recently been linked to the incidence of coronary heart disease. Partially hydrogenated oils and milk and depot fat of ruminant animals are widely regarded as the major sources of dietary TFA. Data concerning TFA contents of industrially prepared food, so-called convenience food, are, however, scarce. Therefore, the fatty acid composition of 52 canned meat products, 51 dry products (soups and sauces), 51 bakery products and snacks, and 74 ready prepared meals (canned or deep-frozen) was examined by gas/liquid chromatography. Canned meat products or prepared meals are no major sources for dietary TFA. Both product groups provided less than 1 g/100 g meat or serving. Contrary to this, dried food items may contain up to 9 g TFA/100 g product.
近期研究表明，膳食中反式脂肪酸（TFA）的摄入量与冠心病的发病率有关。部分氢化油以及反刍动物的奶和体脂被广泛认为是膳食中TFA的主要来源。然而，关于工业化生产食品（即所谓的方便食品）中TFA含量的数据却很匮乏。因此，通过气/液色谱法对52种罐装肉制品、51种干燥制品（汤和酱料）、51种烘焙食品和零食以及74种即食餐（罐装或冷冻）的脂肪酸组成进行了检测。罐装肉制品或即食餐并非膳食中TFA的主要来源。这两类产品每100克肉类或一份食物中的TFA含量均低于1克。与此相反，干燥食品每100克产品中可能含有高达9克的TFA。
