How can I ensure that lactose-free milk lasts longer?

To ensure that lactose-free milk lasts longer, it is important to store it properly in the refrigerator at a temperature of 40°F or below. Make sure to keep the milk container tightly sealed to prevent contamination and spoilage. Additionally, avoid exposing the milk to direct sunlight or heat, as this can accelerate the deterioration process. Finally, always check the expiration date on the packaging and consume the milk before it goes bad to ensure freshness.
