The #10 can is the gold standard of long-term food storage — the same format used by restaurants, the military, and emergency planners worldwide. But how many servings you get from a #10 can varies enormously: a can of powdered milk has 74 servings while a can of freeze-dried chicken has around 11. This guide is the definitive reference.

Why do freeze-dried proteins have so few servings? Fresh meat is 70–75% water by weight. After freeze-drying, the same volume holds much less food than a can of rice or oats. You're paying for 25-year shelf life and concentrated protein — not per-serving economy.

Grains and legumes in #10 cans give you 10–30x more calories per dollar than freeze-dried proteins or vegetables. Build your caloric base from staples, and use freeze-dried proteins and vegetables for nutritional balance and meal variety.
How to Read a #10 Can Label
Serving size: Typically measured in dry volume (e.g., "¼ cup dry") — less than a real cooked portion
Servings per container: Based on the label size — real-world meals may use 1.5–2× more
"As prepared" vs. "as packaged": Freeze-dried calories are measured dry; water adds volume but minimal calories
Net weight: The actual food weight inside, excluding the can itself
Planning tip: Budget 400–500 calories per labeled serving to account for the fact that real-world meal portions tend to be 1.5–2× the label serving size.
Frequently Asked Questions
Why is the serving count on my #10 can lower than I expected?
Label servings are often smaller than real eating portions. A ¼-cup serving of dry rice looks correct on the label, but most people eat ½ cup or more per meal. Always apply a 1.5–2× multiplier when calculating actual meals from a can.
Are all #10 cans the same size?
The can dimensions are standardized (6.25" diameter × 6.9" tall, ~109 oz volume), but the weight of food inside varies — a can of powdered milk is much heavier than a can of freeze-dried strawberries for the same volume.
How do I store a #10 can after opening?
Snap on a plastic #10 can lid and store in a cool, dry location. Most opened freeze-dried products last 6–12 months. Never refrigerate — moisture from condensation accelerates spoilage.
Which #10 can has the most total calories?
Elbow macaroni and pasta cans typically have the highest total calories per can (~10,000 cal), followed by white rice (~7,200 cal). Freeze-dried proteins and fruits have far fewer because of low density in the dried form.
Can I buy single #10 cans or do I have to buy cases?
Safecastle and most suppliers sell individual #10 cans. Cases typically contain 6 cans and often include a discount. Buying individual cans is a great way to try products before committing to a full case.
I received a kindly email saying that an unexpected delay in shipping occurred, but that the order would be fulfilled at the earliest possible time. It would've been helpful to have been given tracking information so that I could have some idea when it might arrive and so leave my gate open.
As it happened, the package was delivered unexpectedly and left outside of the gate. The mill was packaged reasonably well, although the temporary, transport-security base was broken. All of the iron parts were undamaged.
The assembly instructions do not exactly correspond to the model I received, but it was not too difficult to figure out.
As with most metallic items that come into contact with food, I believed that those surfaces should be cleaned with mild soap and warm water before use. However it is not easy to remove the center shaft. I used a rubber mallet to drive out the shaft, the spring augur, and bearings.
After washing, drying, and re-assembly, a test grind produced nice flour, although not as fine a grind as I have gotten with hand-operated stone mills.
The advantage of this mill is easy cleaning of the grind plates and no stone particles in the flour. Also, the mill is nicely heavy and easy to operate, and can be belt driven with a slow-enough electric motor. Step-down gearing could also be used, if necessary.
A suggestion would be to include an exploded-view diagram, showing all of the clearly named parts.
The Owner's Manual makes no mention of it, but replacement parts *might* be available if they are asked for through the chat feature on the SafeCastle website.
The can arrived well packaged & w/ no dents. My wife used the canned ground beef to make beef stroganoff. The result was excellent & every bit as good as store bought hamburger meat. It's just plain ground beef w/ no spices or flavorings added. We liked that because we could flavor it to our taste. Thank you.
