Perhaps many people are surprised that the glass can identify whether the milk is spoiled, because even if the milk is spoiled, its appearance does not change much, so many people cannot clearly distinguish whether the milk is spoiled. So how to use a cup to identify whether the milk has spoiled? let us see.

1. Shake the packaged milk, quickly pour it into the cup, and then pour it out slowly. There may be a few air bubbles, but no lumps.

2. Shake gently with a small amount of water, the white on the wall of the cup becomes evenly lighter;

3. Return to a transparent and clean state again, that is, fresh milk.

4. If the milk film on the glass is uneven, or even has small lumps and small fragments visible to the naked eye, or cannot be rinsed thoroughly with water, or even needs to be scrubbed by hand, it means that the freshness of the milk and the quality of the raw materials are low.

So when we are not sure if the milk is spoiled, if there is a glass nearby, we can use the glass to identify if the milk is spoiled. But pay attention to use the cup to identify good milk, and be sure to do a good job of cleaning the cup, otherwise the residual traces will affect the beauty of the cup.
