unhydrogenated vegetable oil

http://en.wikipedia.org/wiki/Shortening
Shortening is a semisolid fat used in food preparation, especially baked goods, and is so called because it promotes a "short" or crumbly texture (as in shortbread). The term "shortening" can be used more broadly to apply to any fat that is used for baking and which is solid at room temperature, such as butter, lard, or margarine, but as used in recipes it refers to a hydrogenated vegetable oil

Hydrogenation of unsaturated fats produces saturated fats and, in some cases, trans fats.

erst einmal Singular

z.B.: http://en.wikipedia.org/wiki/Trans_fat

Habs gerade schon mal bei "ungehärtet" geschrieben. So wie oben wird es in der Lebensmittelindustrie verwendet.
