我来补答
条件状语从句：If a foodadditive that cannot be used in a food is derived from a raw material for whichthe food additive can be used
【嵌套主句】a foodadditive is derived from a raw material 一种食品添加剂是从一种原料中提取出来的
【修饰 additive定语从句】 that cannot be used in afood 不能在食品中使用的（添加剂）
【修饰rawmaterial 的定语从句】for which the food additive can be used 这种添加剂可以用于的（原料）
主句：the restrictionon the use of food additives may not be applied within the range of suchderiving from the raw material.
【主语】the restrictionon the use of food additives 在使用食品添加剂方面
【谓语】may not beapplied 会是不适用的
【状语】within therange of such deriving from the raw material.在从原料中的这种提取范围内
参考译文：如果一种不能在食品中使用的食品添加剂是从一种原料中提取出来的,而这种添加剂又可以用于该原料,那么在这种来源于该原料的围内使用食品添加剂方面的限制会是不适用的.
