food storage encompasses the methods and practices for preserving dry goods, canned goods, and preserved foods at optimal conditions for extended shelf life. A well-organized food storage system provides food security, reduces waste, and saves money through bulk purchasing. The three pillars of food storage are temperature, humidity, and pest control.
Grains, beans, pasta, flour, sugar, and dried foods are stored in airtight containers to protect from moisture, insects, and rodents. food-grade plastic buckets with gamma seal lids, glass jars, and mylar bags with oxygen absorbers are standard storage containers. The storage area is maintained at 10 to 21 degrees Celsius (50 to 70 degrees Fahrenheit). For every 10 degree Celsius reduction in temperature, the shelf life of dry goods doubles. Oxygen absorbers remove residual oxygen from sealed containers, preventing insect development and rancidity.
Home-canned foods are stored in a cool, dark location at 10 to 21 degrees Celsius (50 to 70 degrees Fahrenheit). Temperature extremes accelerate nutrient loss and can cause seal failure. The jars are stored without the screw bands to prevent rust from hiding a broken seal. The jars are labeled with contents and date. Canned goods are rotated using the first-in, first-out method. Home-canned foods are best used within 1 year, though they remain safe indefinitely if the seal is intact.
Root cellars provide natural cold storage for vegetables. The Root Cellars is maintained at 0 to 10 degrees Celsius (32 to 50 degrees Fahrenheit) with 85 to 95 percent humidity. Different crops require different storage conditions. Potatoes, carrots, and beets store for 4 to 8 months. Cabbage stores for 3 to 4 months. Onions and garlic store for 2 to 6 months in dry, cool conditions. Winter squash stores for 2 to 6 months at 10 to 13 degrees Celsius.
The primary pests of stored food are grain weevils, rice weevils, Indian meal moths, and rodents. Prevention includes cleaning the storage area, inspecting incoming food, and using airtight containers. Bay leaves, diatomaceous earth, and food-grade neem oil are used for insect control. Rodent bait stations and traps are placed around the perimeter of the storage area. Regular inspection catches problems before they spread.
