What’s inside milk?

Let’s imagine that we enlarge a small amount of milk and look what is inside. What will appear is surprising. A fluid landscape reveals that milk is 87% water. That fine mist that embraces everything is mostly sugar such as lactose and mineral salts: an super small multi-colored dust.

Some spheres will appear similar to hot air balloons. Fat globules are straw-yellow in color. Immediately after, a little smaller and irregular spheres of a beautiful ivory hint. They have long barbs, almost like the tentacles of bizarre jellyfish, and these are casein micelles. Caseins are proteins found in large quantities in milk and tend to aggregate with each other and with other substances to form globules, called micelles.

Equally numerous and similar to moray eels are the lactobacilli, bacteria that join together in long, dancing chains. And then, like agile little animals suspended in liquid, there are the albumins, which together with other proteins complete the microcosm of milk.
