牙签是东亚地区普遍使用的洁牙工具,但韩国多数饭馆中的牙签与中国不同,那就是牙签由环保材质制成,甚至可以吃。环保和动物保护风潮则是这种牙签在韩国风靡的主要原因。随着韩国养殖业的发展,食物残余渐渐成为许多养猪场不可或缺的饲料。但是,由于不少传统牙签被混入剩菜剩饭中,致使许多猪在食用后由于牙签戳伤内脏而死亡。随即有人提议,开发出能吃的牙签。1994年,首款淀粉牙签面世,并迅速风靡韩国。这种牙签由土豆、红薯或玉米淀粉制成,长度一般在6厘米左右,颜色为绿色或浅黄色。虽然硬度不如传统牙签,但这种牙签克服了传统牙签很难自然分解的弱点,入水10分钟就会变软。而且,由于其成分与红薯、土豆等相差无几,因此,即使人和动物吃下去也会被消化掉,不会危害健康。 Toothpicks are common toothpaste tools in East Asia, but the toothpicks in most Korean restaurants are different from those in China. Toothpicks are made of eco-friendly materials and can even be eaten. Environmental protection and animal protection is the trend of toothpicks in South Korea swept the main reason. With the development of aquaculture in Korea, food residues have gradually become an indispensable feed for many pig farms. However, since many traditional toothpicks are mixed with leftover food leftovers, many pigs die after being eaten due to toothpicks. Then someone proposed to develop a toothpick to eat. In 1994, the first toothpick came out and quickly swept South Korea. This toothpick made of potato, sweet potato or corn starch, the length is generally about 6 cm, the color is green or light yellow. Although the hardness is not as good as a traditional toothpick, this toothpick overcomes the weakness of the traditional toothpick that is difficult to be naturally decomposed and will soften in 10 minutes. And because its composition is almost the same as that of sweet potatoes, potatoes, etc., even humans and animals will be digested and will not be harmful to health.
