The difference between the shelf life of food (optimum shelf life) and the shelf life of food (recommended final shelf life)
The shelf life of food refers to the period for maintaining the quality (quality) of the food under the storage conditions (such as temperature, humidity, etc.) specified on the label. The food is within the shelf life, fully suitable for sale, and meets the quality standards (quality) specified on the label or in the product standard; beyond the shelf life, the food is still edible for a certain period of time. The shelf life is not equal to the shelf life.
The shelf life refers to the final date when the food can be eaten under the conditions specified on the label; beyond this period, the product quality (quality) may change, so the food is no longer suitable for sale and consumption.
