Most of us know about the five basic tastes (sour, sweet, salty, bitter and umami), and now scientists of Purdue University have found enough evidence to prove that “fat” is the sixth basic taste. 
大多数人都知道五种基本的味觉----酸、甜、咸、苦，鲜。如今，美国普渡大学的科学家们又确认了一种新味觉----肥。

Their research(研究) shows that fat(肥) has the characters of a basic taste(味觉). Not only does ittaste(尝起来) different from the other five, it also cannot be achieved by mixing(混合) other tastes. It is a specific(具体的) and independent(独特的) taste.

The discovery(发现) of the fat taste may lead to a revolution of food(食品革命). Maybe in the future, fat will be extracted(提炼) as a food material, andcucumbers(黄瓜) that taste like roast beef(烤牛肉)will be produced.
