Bacon looks like a great candidate until you look at what it is made of. Pan-fried bacon is about 12% water and around 40% fat, so there is almost nothing for a freeze dryer to remove. The fat stays, and fat at room temperature goes rancid.
Owners who dry bacon bits for camping trips report they keep a few weeks to a couple of months. That is useful, but it is not what most people buy a freeze dryer for.
What to do instead
- If you want bacon bits for a trip: cook crisp, blot hard on paper towels, crumble, dry, and eat within weeks.
- For long storage, buy commercial shelf-stable bacon bits or canned bacon.
- Or dry lean Canadian bacon or ham instead.
