But if it is kept in the refrigerator, the shelf life of pure milk can be extended. This kind of pure milk can be eaten even if it has expired, as long as it has not gone bad. Fresh pure milk is even in texture, milky white and fragrant, while deteriorated pure milk has a certain sour taste, white lump precipitation, and some even change color.

The shelf life on the food label refers to "the date when the food quality is guaranteed under the conditions specified in the label, and the food beyond the shelf life can still be eaten".

The above-mentioned "specific conditions" generally refer to storage methods, such as ventilation, drying and shade. The food is completely suitable for sale and consumption within the shelf life. Foods whose color, fragrance and taste have exceeded the shelf life can still be eaten. For example, beer that exceeds the shelf life can be drunk if there is no loss of light, turbidity, odor, etc.
