In fact, there is room for the shelf life of general milk. Milk can't go bad as soon as it reaches the shelf life, so everyone should judge whether the milk that has expired for one day has gone bad.
You can pour the milk that is one day overdue into a bowl and observe the state of the milk. If milk condenses into lumps or bean curd residue, then milk will go bad. If milk is milky white liquid, it is normal milk and can be drunk.
You can still smell the milk. If it is spoiled milk, it will give off a strong smell, while the smell of non-spoiled milk is milk smell.
Although expired milk can't be drunk, it can also be used to remove stains, water flowers and wipe floors.
Milk contains a lot of lactic acid, which can be used to polish shoes, and can also be added with laundry detergent to wash clothes together.
Although expired milk has lost a lot of nutrients, it still contains some nutrients suitable for plant growth. Watering flowers with diluted milk is beneficial to plant growth.
Expired milk can also be diluted and used to wipe the floor. Milk not only contains lactic acid with strong decontamination ability, but also contains protein, trans fatty acids and other substances, which can form a protective film on the floor, make the floor brighter and protect the floor.
