目前使用的蠟有多種，法定要求都是“可食用蠟”。比如，棕櫚蠟是從棕櫚葉子上提取的，而蟲膠則是寄生于樹上的紫膠蟲分泌的樹脂。經(jīng)過(guò)分離純化，它們可以食用。實(shí)際上，它們?cè)谑称分械膽?yīng)用遠(yuǎn)遠(yuǎn)不止蘋果打蠟。很多需要表面光潔和防止水分散失的食物以及藥片，比如巧克力豆等糖果，藥物膠囊等，都有它們的身影。蘋果打蠟跟其他的食品添加劑一樣，規(guī)范合格的使用不會(huì)危害健康，而帶來(lái)的好處是明顯的。消費(fèi)者不必“談蠟色變”，而應(yīng)該是通過(guò)購(gòu)買來(lái)源可靠的產(chǎn)品來(lái)保護(hù)自己。蘋果在保存運(yùn)輸中，表面也可能會(huì)沾染細(xì)菌或其他東西，所以不管打蠟與否，吃之前都有必要充分清洗。如果實(shí)在不放心，那就削了皮再吃。</p><p style="text-indent:25px">可食用的蠟一般是天然來(lái)源的蠟，來(lái)自于動(dòng)物或者植物，比如蟲膠或者一些植物的膠，像棕櫚蠟，這些東西是天然的且無(wú)
