Researchers in South Korea may soon have a natural, portable answer -- a "Kiss Apple" tiny enough to be stashed in a pocket or purse for quick eating prior to locking lips.

Apples help freshen breath naturally and remove pieces of food stuck in the teeth, but the ping-pong ball-sized apple would be easier to carry around, and far less filling to gulp at a critical moment.

"We can mass produce the species with stronger functions that control food odors in as few as two years," Hwang added.

韩国农业发展部的 Hwang Hye-sung 研究人员欲培养一种新品种的苹果(kiss apple)，它的特点是小巧、切有治疗口臭的作用。

据说这种苹果将只有乒乓球大小，便于携带，你可以随时随地的拿出来咬一口，它就像口香糖一样具有清新口气的作用。当然，同时也可拥有苹果的营养价值。

Hwang Hye-sung 说该苹果可以帮助口气清新自然，同时还可以移除牙缝的残渣。目前计划这种苹果在2年内批量上市。
