Contents of Trans Fatty Acid Isomers (C18:1) in Bakery Products

摘要

Trans fatty acids (TFA) occur in many kinds of foods in varying quantities with trans octadecenoic acid isomers being the predominant TFA. In principle, there are two distinct dietary sources of TFA, industrial partially hydrogenated vegetable oils (PHVOs) and ruminant derived foods (biohydrogenated oils) such as milk, butter, cheese, yogurt, beef, etc. Due torntechnological advantages adherent to the PHVOs (e.g. improved melting behaviour resulting in a better mouth-feeling, increased stability against oxidation), TFA are currently present in a number of food products.
