The shelf life of rice is generally three years, but it can be extended if it is properly preserved. But long-term storage will affect the quality and taste of rice. During the storage of rice, it is easy to get wet and breed bacteria, leading to deterioration. In addition, although vacuum-packed rice can effectively extend the shelf life, it also has a certain time limit.

Although the shelf life has passed, if the vacuum packaging is not opened and the rice has not deteriorated, it can still be eaten in theory. However, the time beyond the shelf life is too long, which has far exceeded the safe consumption period and is not recommended.

In short, in order to ensure the quality and safety of rice, it is recommended to eat it as soon as possible after purchase, and pay attention to the storage conditions. If rice has expired or is improperly stored, it is best not to eat it to avoid health problems.
