日本研发出“微笑”洋葱 让你切洋葱时不再流泪
Chilling an onion reduces the movement of its atoms, resulting in less syn-propanethial-S-oxide（顺式-丙硫醛-硫化物） – the tear-inducing lachrymatory（催泪的） agent – being released when cut, but that only reduces the number of tears you shed. 将洋葱冷冻能减少洋葱原子的运动，从而减少顺式-丙硫醛-硫化物的释放，这种气体就是“催泪弹”——洋葱被切时就会释放。但是切冷冻洋葱只能减少流泪。
Chopping the Smile Ball onion in any conditions is reportedly a tear-free experience.切“微笑洋葱”，不管是冷冻还是常温，都能给你带来“无泪”体验。
Last year, when it made its big announcement, House Foods Group revealed that it managed to suppress（抑制） the production of syn-propanethial-S-oxide by bombarding（照射） onion bulbs with irradiating ions, which also made the vegetables less pungent. 去年，House食品集团隆重宣布，他们用辐射离子照射洋葱，已经成功抑制了顺式-丙硫醛-硫化物的生成，还能减少洋葱的刺鼻气味。
Full-grown Smile Ball onions release almost no tear-inducing compounds when chopped or eaten raw.不管是在切洋葱时还是生吃时，成熟的“微笑洋葱”几乎不会产生催泪成分。
About five tons of Smile Ball onions were sold in trial runs at Tokyo department stores and online shops this year, but come fall, they will be available at supermarkets nationwide, at a price of 450 yen ($4.30) for a pack of two. That’s twice as expensive as regular onions.今年已有约五吨“微笑洋葱”在东京百货商店和网店试销，等到秋季时将会进入日本各地超市，一包两个的售价是450日元（合4.3美元），比普通洋葱贵了一倍的价钱。
The rate at which the trial batch of 5-6 tons of Smile Ball onions sold out signals that they will be a huge hit when they hit the market, but skeptics worry that they will have the same fate as apples, which many say have lost most of their original flavor after years of selective breeding.这批五六吨的“微笑洋葱”被抢购一空的速度，预示着它未来在市场的巨大成功，但是有怀疑论者担心新型洋葱会步苹果的后尘——苹果曾经经历了数年的选择性培育，以至于丧失了原有的风味。
