Temporary products refer to foods that are about to reach the shelf life of food, but still within the shelf life, and belong to the scope of safe food. For example, the "temporary food counter" in the supermarket sells temporary food. The temporary food can be eaten, and the temporary food is still within the shelf life, thus maintaining the quality of the food. In addition, many foods beyond the shelf life can also be eaten, and these foods near the shelf life are safe and reliable. Although it is imminent, it is still within the shelf life of the product, so it belongs to safe food; Can reduce the waste and environmental pollution of destroyed food in the process of returning to the factory for reprocessing; They are usually sold at a discount, so the price is relatively low.

"Temporary food" belongs to a concept of consumers. It is usually called "stock/tail grain" in the industry. Whether it is discount grain storage or discount grain store, it is the middle and lower reaches of this supply chain. Therefore, this kind of food is not completely measured by the shelf life, but by the "unsalable degree". Although some foods are far from the shelf life, the inventory pressure is high and the price is lower; On the contrary, some of them are close to the shelf life, but they are not too difficult to sell and the discount is relatively small. For temporary food, in order to leave time for turnover, we tend to purchase goods with a shelf life of at least 3-4 months or even longer.
