If an oil or fat is hydrogenated, people have treated it with hydrogen so a liquid oil becomes firmer — more like a solid. Factories do this to turn cheap plant oils into something that spreads like butter, or that can sit on a shelf for a long time without going off.

If an oil or fat is hydrogenated如果一種油或脂肪是hydrogenated的, people have treated it with hydrogen就是有人用氫處理過它 so a liquid oil becomes firmer讓液態油變得比較固, more like a solid更像固體. Factories do this工廠這樣做 to turn cheap plant oils是為了把便宜的植物油變成 into something that spreads like butter像奶油一樣好塗抹的東西, or that can sit on a shelf for a long time without going off或是能在架上放很久不變質的東西.

You see the word on food labels: hydrogenated oil, hydrogenated fat, partly hydrogenated vegetable oil. Chemists can hydrogenate other things too, but in ordinary English this word almost always points at food fats.

You see the word你會 on food labels在食品標籤上看到這個字: hydrogenated oil, hydrogenated fat, partly hydrogenated vegetable oilhydrogenated oil（氫化油）、hydrogenated fat（氫化脂肪）、partly hydrogenated vegetable oil（部分氫化植物油）. Chemists can hydrogenate other things too化學家也可以把別的東西氫化, but在日常英文裡 in ordinary English this word almost always points at food fats這個字幾乎都是指食品裡的油脂.

Though actually, “partly hydrogenated” oils are the ones that make trans fats, which many countries now try to limit; fully hydrogenated fat is a different, harder product. The word sounds scientific and a bit industrial — not a compliment in food talk these days.

Though actually不過其實, "partly hydrogenated" oils「部分氫化」的油 are the ones that make trans fats才是產生反式脂肪的元兇, which many countries now try to limit這也是許多國家現在想限制的東西; fully hydrogenated fat完全氫化的脂肪 is a different, harder product則是另一種比較硬的產品. The word sounds scientific and a bit industrial這個字聽起來很科學、有點工業感 — not a compliment in food talk these days在現在的飲食話題裡不算是稱讚.
