How To Freeze Dry Corn
Welcome to our guide on how to freeze dry corn. Freeze drying corn is a simple way to preserve its flavor, nutrients, and texture for long-term storage.
This process removes the moisture from the kernels while retaining their shape, making them lightweight and shelf-stable for years.
Freeze-dried corn can be used for snacks, soups, casseroles, or any recipe where you want the fresh taste of corn without worrying about spoilage.
No matter if you’re using fresh corn from the cob or frozen kernels, freeze drying helps you get the most out of your harvest or grocery haul.
The first time I learned about freeze drying corn, I was amazed at how easy it was to prepare and store. After cutting it off the cob, just place it into the freeze dryer and let the machine do it’s thing.
You will get perfectly preserved corn that rehydrates beautifully for your recipes. Freeze drying has become a go-to method for preserving my favorite vegetables, and corn is one of the easiest to start with.
I love this way of preserving this type of food because you can get corn on the cob pretty cheap during harvest time and just do a ton of batches.
How To Freeze Dry Corn
Step 1: Prepare the Corn
Remove the husks and silk. Cut the kernels off the cob using a sharp knife or corn stripper. Then wash the corn. For frozen corn, there’s no need to thaw it; you can use it directly from the freezer.
Step 2: Load the Freeze Dryer Trays
Spread the corn kernels evenly across the Harvest Right trays. You can load up the trays, but don’t go above the tray line.
Step 3: Place Trays in the Harvest Right Freeze Dryer
Insert the loaded trays into your Harvest Right freeze dryer. Close the chamber securely and select the appropriate setting for vegetables or customize the settings if needed.
Step 4: Start the Freeze-Drying Process
Begin the freeze-drying cycle. The Harvest Right machine will freeze the corn first, then create a vacuum to remove moisture through sublimation. This process typically takes about 24 hours, depending on the moisture content and the size of your load.
Step 5: Package and Store the Freeze-Dried Corn
Once the cycle is complete, remove the trays and check that the corn is fully dried. The kernels should be crisp. Transfer the freeze-dried corn into airtight containers like a mason jar with oxygen absorbers for long-term freshness. Store in a cool, dry place.
Freeze Drying Corn FAQ
1. Do you need to blanch corn before freeze-drying?
Blanching is optional. While blanching can help preserve color and texture for long-term storage, it is not necessary for freeze-drying which is different than putting it in the freezer. You can freeze-dry fresh or cooked corn, depending on your preference and how you intend to use it later
2. How do you prepare corn for freeze-drying?
Easy! Start by removing the kernels from the cob and giving them a wash. You can stack up the corn, but make sure they are not overflowing over the tray. Try to even them out as much as possible.
3. How long does it take to freeze-dry corn?
Freeze-drying will usually take about 24 hours with the Harvest Right Freeze Dryer. It will depend on your freeze-dryer model and the moisture content of the corn.
The nice thing about the Harvest Right freeze dryers is that they have automated settings that you program in.
4. Does freeze-drying corn preserve its nutrients?
Yes, freeze-drying is one of the best preservation methods for retaining nutrients in the corn. The process removes water while keeping the structure and most of the nutrients intact.
5. How should freeze-dried corn be stored?
After freeze-drying, store the corn in airtight containers or mylar bags with oxygen absorbers. I like to keep my freeze dried food in glass mason jars for long term storage. You can also use a vacuum sealer for jars.
Keeping it in a cool, dry place will give it a shelf life of up to 25 years.
For freeze dried corn that I use often in my pantry, I use the flip top jars with lids.
6. My freeze dried corn is clumping after storage.
It’s important to make sure that your food is completely freeze dried so that no moisture is in the kernels. If you go ahead and use your corn months or years later and it is clumpy, it might not be ok anymore. Freeze dried food does not stick together.
