【单选题】
许多民众认为奶粉的营养比不上鲜奶，乳企不该在乳制品中使用奶粉。同时，一些乳业专家也认为。由液态奶制成乳粉的过程需要经过两到三次提温脱水，而由乳粉再制成复原乳的时候。还要再重新加水、加温和消毒，数次提会造成营养成分的流失。而美国农业部的一份关于复原乳和鲜奶营养成分对比的数据显示，牛奶中的主要营养成分蛋白质、钙元素和脂肪，在复原乳中并没有流失．只有B族维生素有l0％至20％的损失，但是人体摄取维生素的途径不是牛奶．因此复原乳在营养上和新鲜牛奶差异不大。 文段意在说明的是：A.
复原乳经多次提温致使营养成分流失
B.
从营养角度看。复原乳和鲜奶差别不大
C.
从营养价值来看，复原乳明显高于鲜奶
D.
乳企更青睐复原乳缘于其安全性鲜奶
