Prompt refrigeration and pasteurization delays spoilage. It helps to reduce the bacterial load from the beginning. That would mean maintaining a healthy herd and utilizing sanitary milking procedures.
Once milk has been purchased, keeping the milk below 40°F will help obtain maximum shelf life.
Milk turning sour is a chemical change. It occurs due to the fermentation of milk sugars by bacteria, leading to the production of lactic acid, which changes the taste and smell of the milk.
No, milk turning sour is a chemical change because the bacteria in the milk interact with the lactose to produce lactic acid, changing the composition of the milk.
The independent variable in turning milk into plastic would be the process or conditions under which the milk is treated or transformed. The dependent variable would be the resulting properties of the plastic formed from the milk, such as its strength, durability, or other characteristics.

Yes, milk turning sour is a chemical change. This is because the bacteria present in the milk ferment the lactose sugars, producing lactic acid which changes the chemical composition of the milk, resulting in the sour taste and smell.
To prevent milk from turning sour when making sour milk, you can add a small amount of vinegar or lemon juice to fresh milk to curdle it, rather than letting it naturally sour over time. This will give you the desired sour flavor without the risk of the milk going bad.
the sugar in the milk is carmelized thus turning brown.
Try turning the heat down.
Putting acids on a apple will not stop it turning brown as the apple is an acidic fruit itself so adding more acid would make it turn brown quicker.If you wanted to delay the browning of an apple you can always try neutrelising the apple by milk or something neutrel .It may no taste that great though .
During summers, milk can turn sour due to a chemical change called souring. This is caused by the growth of bacteria in the milk, which metabolize the lactose (milk sugar) into lactic acid. The lactic acid decreases the pH of the milk, giving it a sour taste and causing the proteins to denature.
It's not a physical change
stop it from overheating
