Can vacuum-packed rice be eaten if the packaging has lost its vacuum but hasn't expired?

In general, whether vacuum-packed rice that has lost its seal but has not expired is still edible depends on the specific circumstances. The detailed analysis is as follows:

If the rice has been exposed due to a short-term leak and, upon opening, the grains appear plump, glossy, and odorless, and feel dry, loose, and free of clumping or mold when pinched, it is generally safe to eat. This situation usually results from minor packaging damage, with the rice having had limited exposure to moisture and contaminants. After thorough washing and normal cooking, it should not pose any food safety risks.

However, if the rice has been exposed for a prolonged period and, upon opening, emits a musty or rancid odor, appears yellowish or dull, shows clumping or stickiness, or displays visible mold spots or insect infestation, it should not be consumed—even if it is still within the expiration date. Once air and moisture enter the package, mold and pests can easily develop, potentially producing harmful substances that may cause gastrointestinal discomfort after consumption.

When purchasing rice, check the packaging for integrity and inspect any packages that have lost their vacuum seal. After opening, store the rice in an airtight container in a cool, dry place, away from direct sunlight and humidity, and consume it as soon as possible within the shelf life.
