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.

韓國農(nóng)業(yè)發(fā)展部的 Hwang Hye-sung 研究人員欲培養(yǎng)一種新品種的蘋果(kiss apple)，它的特點是小巧、切有治療口臭的作用。

據(jù)說這種蘋果將只有乒乓球大小，便于攜帶，你可以隨時隨地的拿出來咬一口，它就像口香糖一樣具有清新口氣的作用。當然，同時也可擁有蘋果的營養(yǎng)價值。

Hwang Hye-sung 說該蘋果可以幫助口氣清新自然，同時還可以移除牙縫的殘渣。目前計劃這種蘋果在2年內(nèi)批量上市。
