Expiration & Storage Tips
When does sushi rice expire?
Uncooked sushi rice, if stored properly, can last several years beyond its printed expiration date. Once the rice is cooked, it should be consumed within 4 to 6 hours at room temperature to prevent bacterial growth. If you have leftovers, they should be refrigerated immediately and eaten within 1 to 2 days. As for the sushi rice that is already mixed with seasoning, it is recommended to consume it on the same day without storing it, as it may lose its taste and texture.
How do you tell if sushi rice is bad?
The signs of spoiled sushi rice are quite discernible. Uncooked rice will develop a musty or off-odor and could have discoloration or visible mold. Cooked rice will have a sour smell, a change in texture or color, and could also accumulate mold if left for too long. Always trust your nose and eyes when it comes to identifying spoiled food, if it looks or smells off, discard it immediately to avoid foodborne illness.
Tips for storing sushi rice to extend shelf life
• Store uncooked sushi rice in an airtight container in a cool, dark pantry to prevent moisture and pests.
• Cooked sushi rice should be mixed with the vinegar dressing while it's still hot and left to cool at room temperature. It should not be refrigerated or reheated as it changes the texture.
• If you need to store cooked sushi rice, refrigerate it immediately after the 4-6 hour room temperature window. Eat it within the next day or two.
• Lastly, never mix seasoned and plain rice together. The vinegar in the seasoning could affect the unseasoned rice's freshness.
