Storage Tips
Store below 70°F (21°C) for maximum shelf life
Use food-grade 5 mil or thicker mylar bags
Label bags with date and O2 absorber size
Store sealed bags inside 5-gallon buckets for pest protection

Not removing enough air before sealing
Storing in direct sunlight or near heat sources
Using pre-activated oxygen absorbers
White Rice Storage FAQ
How long does white rice last in mylar bags?
White rice in sealed mylar bags with oxygen absorbers lasts 25-30 years at room temperature. Without O2 absorbers, shelf life drops to 1-2 years. Key factors: 5 mil minimum thickness, seal integrity, 300cc absorbers per gallon, and storage below 70°F.
What size oxygen absorber for rice?
Use 300cc per 1-gallon bag or 2000cc per 5-gallon bag. Rice is dense with less airspace, so standard sizing works well.
Can you store brown rice long term?
Brown rice only lasts 1-2 years in mylar due to natural oils that go rancid. White rice, parboiled rice, or instant rice are better for 10+ year storage.
Should you freeze rice before mylar storage?
Freezing 48-72 hours kills insect eggs. While O2 absorbers suffocate insects, pre-freezing adds insurance, especially for bulk warehouse purchases.
