Freeze-Drying Frequently Asked Questions
WeFreezeDryIt — professional freeze-drying services in Panama, based in Coronado, Panamá Oeste. We help families, farms, pet owners and food businesses turn fresh foods, meals, snacks and ingredients into lightweight, flavorful, shelf-stable products. Here are straightforward answers to the questions we hear most — including what freeze drying does, and what it does not do.
Packaging & Storage at a Glance
How long a freeze-dried food lasts depends on more than the freeze dryer. The main factors are:
- Residual moisture left in the food
- Oxygen exposure
- The barrier quality of the packaging
- Heat
- Humidity
- Light
- The food’s composition
- Fat content
In Panama’s humid climate, freeze-dried foods should be packaged promptly after processing because they can quickly absorb moisture from humid air. For long-term storage, properly heat-sealed Mylar bags with appropriately sized oxygen absorbers are commonly used where suitable. Other options, such as vacuum-sealed bags or jars, can work well for some products and shorter storage periods — the best choice depends on the food and how you plan to use it.
Common Questions
Does freeze drying kill bacteria?
No. Freeze drying is a preservation process, not a sterilization process. It does not kill all bacteria or pathogens that may already be present in food. Removing water greatly slows microbial activity, but microorganisms can survive in a dormant state and become active again when the food is rehydrated. That is why safe ingredients, clean handling and proper cooking (where needed) matter.
Can you freeze dry raw meat?
Technically, some raw meats can be freeze dried. However, freeze-dried raw meat is not ready to eat — it should still be cooked before eating unless it was fully cooked before freeze drying. Raw meat projects are reviewed case by case.
How long does freeze-dried food last?
It varies by food, residual moisture, fat content, packaging and storage conditions. Many properly freeze-dried foods can last for many years in high-barrier packaging stored in cool, dark, dry conditions, and some products may potentially last decades. High-fat foods generally have a shorter storage life because freeze drying removes water, not fat.
Do you remove 100% of the water?
No. Freeze drying removes the vast majority of a food’s water — approximately 98–99% is typical under appropriate processing conditions — but a small amount of residual moisture remains. Final moisture levels vary depending on the food, product thickness, load and processing conditions.
Does freeze drying preserve nutrients?
Generally very well, especially compared with high-temperature drying methods, because the process uses low temperatures. Nutrient retention varies depending on the food, the specific nutrient, preparation method, processing conditions and storage.
Why does packaging matter?
Freeze-dried food is very dry and porous, so it can quickly absorb moisture from the air and is vulnerable to oxygen and humidity. Good packaging — sealed promptly after processing — is what protects the texture, flavor and storage life you paid for.
What does WeFreezeDryIt do?

How do I start a project?
Fill out the quote form with a short description of your product — ingredients, raw or cooked, approximate quantity or fresh weight, intended use and desired packaging. Most projects are reviewed before processing, and we will reply with recommendations and a quote.
Which foods can you freeze dry?
Most fruits, vegetables, herbs, cooked meals, candies and many ingredients freeze dry well. Raw meats, seafood, dairy, raw eggs, very high-fat or syrup-heavy products and products for resale need additional review. Pure oils, butter, high-oil nut butters and honey generally do not freeze dry well. See our Food Acceptance Policy for details.
