首先干燥环节。简单来说，就是给牛奶脱水。在高温条件下，将鲜牛奶进行浓缩、干燥，然后再进行快 速脱水，将鲜牛奶变成乳粉状态。这一过程可以大大延长牛奶的保质期，减少体积和重量，便于以后的 储存和运输。 从奶粉到牛奶，你知道复原乳是怎么生产出来的呢？今天就用一篇带你了解一下复原乳的奇妙"再生"之 旅吧。 复原乳的生产主要有两个环节：干燥-还原。 那么经过这样生产出来的复原乳，和鲜奶会有很大的差别吗？核心营养差不多，但细节有不同。 尽管复原乳的生产过程会经过两次高温灭菌，但核心营养蛋白质、脂肪、钙质，在高温中很稳定，都被 很好地保留了下来。并且含量和鲜牛奶中的含量相差不大。而在口感上，奶味会比鲜牛奶淡一些，不过 也有它的独特风味。 从新鲜的牛奶变成干燥的奶粉，再到加入温水"重生"为复原乳，这不仅仅是形态的简单变化，更是食品 科技的智慧结晶。它解决了鲜奶易腐坏、难运输的难题，让牛奶的核心营养能以更灵活、更稳定的方 式，突破时间和空间的限制，送到更多需要它的人手中。 其次还原过程。在干燥好的乳粉中，按照一定的比例，添加适量温度的水。将乳粉充分搅拌溶解。再利 用匀质机，对溶解好乳液，进行进一步地打碎，使脂肪球的颗粒更小，更 ...
