Can rice be eaten after being stored for 2 years?

If vacuum rice is not opened and left for two years, it can be eaten without shelf life and deterioration. However, unpackaged vacuum rice is not recommended to be eaten after two years. The longer the storage time of rice, the lower the internal enzyme activity and the looser the overall structure. When rice goes bad, it is very easy to grow insects, and soon it will lose its quality, color and flavor, and its nutrients will be greatly reduced.

In most cases, rice can be eaten normally as long as the package is intact and there is no mildew, odor and discoloration after opening. But if the time is too long, the moisture in the air will enter through air oxidation, which will lead to discoloration and mildew due to the influence of moisture.
