Quick Answer
For long-term storage of grains in Mylar bags, combine them in 5-gallon buckets, layering rice, beans, and grains, followed by a moisture barrier, a desiccant packet, and a Mylar bag. Ensure oxygen removal and seal the bag properly with a FoodSaver or similar device. This setup protects against pests, moisture, and oxygen.
Preparing the Storage Bucket
To store grains in Mylar bags for 25 years, start by selecting a 5-gallon food-grade bucket. Ensure the bucket is free from any contamination or residual odors. Clean the bucket with hot water and mild detergent, then thoroughly rinse and dry it.
Packaging the Grains
Begin by filling the bucket with a base layer of rice or beans, about 1-2 inches deep. Add a 1-inch layer of grains, followed by a 1-inch layer of beans or rice. This alternating pattern helps maintain even weight distribution and prevents the bags from shifting during storage. Repeat this process until the bucket is about 3/4 full.
Sealing the Mylar Bags
After adding the final layer of grains, place a moisture barrier, such as a 5-mil Mylar sheet, over the top of the bucket. This barrier prevents moisture from entering the bucket. Add a desiccant packet, like silica gel or calcium chloride, to absorb any remaining moisture. Finally, place a Mylar bag over the top of the bucket and seal it using a FoodSaver or similar device designed for removing oxygen and sealing food storage containers. This ensures a long-lasting, airtight seal that protects the grains from pests, moisture, and oxygen.
