Milled rice (white, parboiled or pre-cooked):
If stored properly, milled rice will keep almost indefinitely on the pantry shelf. Once opened, rice should be stored in a tightly-closed container that keeps out dust, moisture and other contaminants.
Whole grain rice(brown, red or black):
Because of the oil in the bran layer, this rice has a shelf life of approximately 6 months. Refrigerator or freezer storage is recommended for longer shelf life.
Cooked rice may be stored in the refrigerator for 3 to 5 days or frozen up to 6 months. USDA recommends to cool to 70 °F within 2 hours and from 70 °F to 40 °F within an additional 4 hours. Hold cold rice at 41 °F or below.
