Milk souring is a chemical change that can occur when milk is heated. The souring process is caused by the action of hydrolysis, which is the breaking down of lactose into lactic acid and glucose.
Lactic acid is a souring agent, and glucose is a sweetener. When milk is heated, the lactic acid and glucose combine to form a souring solution. This solution can be expelled through the nose or mouth, and it can also be used as a food additive.

What chemical reaction happens in bread?
Bread baking is a chemical reaction that happens when the air-liquid interface of two doughs comes into contact. The dough is heated up from the air and the liquid is drawn up into the dough.
This causes the liquid to vaporize and the gas to be released. The gas forms a plume that rises and forms a bread dough cloud. This dough cloud is then baked and the gas bubbles escape and break down the bread dough.
Why is baking a chemical change?
Baking a chemical change is a common reason why food tastes different after it has been baked. The baking soda in food reacts with the water in the dough to produce an egg white.
When the oven is turned on, the heat from the oven vaporizes the soda, which then creates an acidic environment. The acid in the dough causes the baking soda to react with the salt in the flour, which creates a baking soda and salt mixture. This mixture is then baked in the oven.
