Boiled milk should be stored with a lid in the refrigerator to prevent contamination and absorption of odors. Leaving it uncovered can lead to spoilage and affect its taste.
Boiling milk helps to kill bacteria and extend its shelf life. However, once boiled, it's crucial to cool it down quickly and store it properly to prevent recontamination. Leaving boiled milk uncovered exposes it to airborne bacteria, dust particles, and other contaminants present in the environment. These contaminants can multiply rapidly, especially at room temperature, leading to spoilage and making the milk unsafe to drink. Furthermore, milk readily absorbs odors from its surroundings. An uncovered container allows the milk to absorb smells from other foods in the refrigerator, altering its taste and quality. Using a lid creates a barrier against these external factors, preserving the milk's freshness and flavor for a longer period.
Cool the boiled milk to room temperature before refrigerating it. Placing hot milk directly into the refrigerator can raise the internal temperature of the appliance, potentially affecting the safety of other stored foods.
