Transition of trans Fatty Acid Contents of Margarines, Fat Spreads and Shortenings in Japan
1Japan Association for Inspection and Investigation of Foods Including Fats and Oils.
Abstract:
Margarine, fat spread, and shortening made with partially hydrogenated fats and oils as their raw materials have been known as foods containing trans fatty acids. Due to concerns about the health effects of trans fatty acids, the content of trans fatty acids in these products has now been reduced to around 1 g/100 g (median value) through the use of alternative oils and fats, which is about the same level as that for vegetable oil used as main raw material. In this review, we summarized the trends in trans fatty acid content in products manufactured in Japan from 1969 to 2022.
