Now, supermarkets in Sweden have started doing just that. Labeling fruit with a laser is actually quite simple. The skin of many fruits and vegetables changes color when put under bright light. A laser shoots out light that is extra bright and strong, so it makes a very clear mark. The mark is safe to eat and doesn't change anything other than the skin. While the laser used to mark the food is expensive, it saves money in the long run.

現在,瑞典的超市已開始使用雷射標籤。在水果上雷射出標籤其實相當簡單。許多水果及蔬菜的表皮在強光照射下都會改變顏色。雷射裝置所照射出的光特別明亮強烈,所以能產生非常清楚的印記。這個印記在食用上很安全,除了蔬果的表皮之外不會造成任何改變。雖然用來標記食物的雷射裝置很昂貴,長期使用下來卻能省錢。
