What can be done with expired pure milk

Expired pure milk is not recommended for consumption, but can be used for skincare, cleaning, or watering plants. Expired milk may breed bacteria, and direct consumption may cause gastrointestinal discomfort. The lactic acid component in expired milk has a softening effect on keratin and can be used for skin care. Mixing a small amount of expired milk with warm water before washing your face can help improve rough skin. The protein in milk can bind with dust, and wiping leather furniture or wooden floors with expired milk can have a cleaning and polishing effect. Plant growth requires calcium, and diluted expired milk can be used as a nutrient solution to irrigate acid loving plants such as rhododendrons and camellias. If expired milk shows clumping, discoloration, or a sour taste, it indicates severe spoilage and should be discarded immediately. Even if there is no significant change in appearance, a large number of microorganisms may have grown inside, and it needs to be boiled and disinfected before use for skincare or cleaning. After using expired milk, redness, swelling, and itching may occur on the skin. Rinse with water and stop using.

Milk should be stored in the refrigerator's refrigeration layer for daily use, and should be consumed as soon as possible after opening. Pay attention to checking the shelf life when purchasing to avoid hoarding too much and causing waste. If the milk is about to expire but has not deteriorated, it can be heated to make facial mask or baked food. High temperature can effectively kill some bacteria. It is recommended to purchase milk reasonably based on household consumption to ensure freshness and reduce resource waste.
