That's right, kiss, the soup is a very test of the heat.

The reasons why the old soup gets darker the more you cook, are as follows:

1. There are more and more impurities and oxides in the soup;

2. Impurities, impure components mixed in a substance, their forms include solid granules, fibrous, soft gelatinous, liquid, and gaseous. Generally, we consider liquids with impurity content not exceeding 0.03% as impurity-free;

3. Oxide is a binary compound composed of negative valence oxygen and another chemical element, such as iron oxide and alumina, which is usually produced by oxidation reaction. Oxides are extremely common in the earth's crust, and the same is true in the solids of the universe, free oxygen ions are strongly alkaline, and are unstable in aqueous solution, and oxidation is very easy to discolor the solution.
