As a result, the mixture is more acidic than before, and this higher acidity solidifies the casein proteins.
因此，混合物比之前更酸，高浓度的酸使酪蛋白凝固。
The whey proteins, on the other hand, don’t solidify, and separate out from the casein as liquid.
而另一方面，乳清蛋白不会凝固，所以会从酪蛋白中以液体的形式分离出来。
Yogurt you buy in the store has a stabilizer, usually fruit pectin, to keep the solid casein and liquid whey mixed together.
超市里销售的酸奶含有一种稳定剂，通常为果胶，它的作用是让凝固的酪蛋白与液体的乳清结合为一体。
But some of the whey still separates out from the casein, and that’s what you see when you open the yogurt container.
不过，部分乳清仍然会从酪蛋白中分离出来，正如你打开酸奶包装时所看到的液体。
Whey contains not only proteins but also B vitamins, including riboflavin, niacin, and thiamin, which can’t be found in the solid portion of the yogurt.
乳清不仅富含蛋白质还有维生素B，包括核黄素，烟酸和硫胺素，这些物质在凝固的酸奶中是不存在的。
Because of the nutritional value of whey, your best bet is to mix it back into the rest of the yogurt, then gobble it down!
鉴于乳清丰富的营养价值，你最好把它和酸奶搅拌在一起，然后一口气喝完！
