洋葱是厨房里最常见的蔬菜之,但切洋葱时产生的刺激气味常使人流泪,让不少人对它又爱又恨。不过,上述情况可能很快成为历史。日本一家食品公司3月31日宣布,公司研发出一种“无泪”洋葱,让人们在切它时不会再流泪。公司科研人员发现,切开洋葱时的气味中含有一种刺激人流泪的物质。科研人员设法通过一种离子大幅减少这种刺激物,从而使洋葱气味不再刺激流泪。公司一名发言人表示,目前尚未决定是否会把这种“无泪洋葱”投入商业化生产。 Onion is the most common type of vegetable in the kitchen, but the pungent smell of cutting onions often makes people cry and makes many people love and hate it. However, the above situation may soon become history. A Japanese food company announced on March 31 that the company has developed a “no tears” onion so that people will not shed tears when cutting it. Company researchers found that the smell when cutting onions contains a substance that stimulates the weeping of people. Researchers have managed to dramatically reduce such irritants with an ion, so that onion odor no longer stimulates tearing. A spokesman for the company said it has not yet been decided whether to put this “onion-free” into commercial production.
