smoke point(冒烟点/烟点):指食用油脂或其他脂肪在加热时开始持续冒烟的温度。超过这个温度,油脂更容易分解,产生刺鼻烟雾与不良风味,也可能生成对健康不利的分解产物。(不同油的烟点差异很大,且会受精炼程度、杂质与使用次数影响。)
/ˈsmoʊk pɔɪnt/
Heat the oil to its smoke point, then add the vegetables.
把油加热到冒烟点,然后再下蔬菜。
Because the pan was too hot and the olive oil had passed its smoke point, the kitchen filled with smoke and the fish tasted bitter.
因为锅太热、橄榄油已经超过冒烟点,厨房里全是烟,鱼也带了苦味。
该短语由 smoke(烟/冒烟)+ point(点、临界点/温度点)构成,字面意思是“开始冒烟的那个临界点”。在烹饪与食品科学语境中,它用来描述油脂受热到一定温度后开始可见冒烟的阈值,并常用于指导煎、炒、炸等高温烹调方式的选油与控温。
