What is the use of expired sweet milk

Expired sweet milk is not recommended for consumption, but can be used for non edible purposes such as watering plants, cleaning, or making handmade soap. Sweet milk may breed bacteria and spoil after expiration, posing health risks when consumed directly. Expired sweet milk contains organic components such as lactic acid, which can be diluted and used as natural fertilizer to irrigate acid loving plants such as azaleas and gardenia. When using, it is necessary to mix water in a ratio of 1:3 to avoid excessive concentration and damage to plant roots. For leather products, a soft cloth dipped in a small amount of expired milk can be used to wipe the surface. Its fat content can have a polishing effect, but after treatment, a dry cloth should be used to wipe off any residue. Mixing expired sweet milk with coconut oil and sodium hydroxide can make a simple handmade soap, but attention should be paid to the safety of the ratio and avoid contact with eyes. If the sweet milk has clumped, has a sour odor, or has abnormal color, it can only be discarded. This type of spoiled milk may contain a large amount of pathogenic bacteria, and even boiling at high temperatures cannot completely eliminate toxins. Some people try to ferment expired milk to make cheese or facial mask, but it is difficult to control the contamination of miscellaneous bacteria in the family environment, which may cause skin allergy or gastrointestinal discomfort.

Sweet milk should be stored in the refrigerator compartment for daily use, and must be consumed within 48 hours after opening. If any abnormal situations such as packaging expansion or leakage are found, they should be immediately discarded. The safety of reusing expired food needs to be carefully evaluated. When it involves skin contact or household cleaning, it is recommended to try it on a small scale first. The safest way to dispose of dairy products that are uncertain about spoilage is to follow food safety principles.
