Blanch your veggies before freezing, drying, or freeze drying. Blanching vegetables is an essential step in food preservation to ensure that your produce retains its color, texture, vitamins and flavor during storage. Don’t skip this essential step when you preserve vegetables at home.
Do you blanch before freeze-drying?
I always recommend blanching certain foods before freeze-drying. Think of it the same way you would about home canning. Blanching helps the food to be the right texture and color when you cook foods later. It works the same with freeze-drying.

The natural enzymes in corn need to be inactivated before freezing to prevent both loss of color and nutrients, and flavor and texture changes. These enzymes are inactivated by a hot blanch treatment. The chilling process prevents the corn from becoming mushy due to overcooking the starch.
Can raw meat be freeze-dried?
Raw Meats vs Cooked Meats
You can freeze dry both raw or cooked meat and get great results. If you freeze-dry an already-cooked steak, you won’t need to worry about flavoring it when it is rehydrated and it will also be more food-safe as it rehydrates.

What are the disadvantages of blanching?

What happens if you don’t blanch broccoli before freezing?
Broccoli — florets and stems — must be blanched for effective freezing. If you freeze it raw, you’ll wind up with bitter, drab green, shriveled stems. Blanching preserves the bright green color and tasty flavor. You can either blanch in boiling water for three minutes or steam for five minutes.
What happens if you don’t blanch cauliflower before freezing?
Blanching locks in a vegetable’s nutritional content and ensures a pleasant texture when you go to cook with it. Freezing fresh cauliflower might result in a mushy texture, but if you must, we recommend ricing the cauliflower first to avoid any weird textural changes.
What vegetables can you freeze without blanching?
Except for onions and peppers, which you can freeze raw, you should blanch or fully cook vegetables before freezing. Blanching vegetables, or dunking them into boiling water, stops the enzymes that cause discoloration and turn frozen produce mushy. Raw fruit, on the other hand, freezes just fine.
Does celery need to be blanched before freeze drying?
You don’t necessarily have to blanch the celery before freezing, but it will preserve the flavor for longer. Dry. Drain the celery in a colander.
Do I need to blanch zucchini before freeze drying?
Don’t pre-cook.
Precooking can just turn them to powder. Not what you want. I don’t like to use the ends of the zucchini for freeze drying, but I also don’t like to waste food. I usually put the ends into the compost for my garden.
What happens if you don’t blanch corn before freezing?
This is because the process of blanching destroys enzymes that can change the flavor, texture, and even the color of vegetables, including corn, during their time in the freezer. Corn that has not been blanched before freezing can become chewy (and sometimes downright mushy) once it’s thawed.
How long do you blanch corn before freezing?
Corn on the Cob

Does freeze-dried food need to be vacuum sealed?
All you need to do is make sure they are sanitized and add an oxygen absorber to lock your food up nice and tight for the long haul. (Some choose to use a vacuum sealer to seal their jars, but it’s vital that all the oxygen is removed when using this method.)
Can I freeze dry bacon?
Raw bacon can be readily freeze dried to a moisture content of less than 1.0 percent. In fact, I have freeze dried raw bacon to as low as about 0.7 percent moisture. In general, the lower the moisture content of the freeze-dried raw bacon, the better its storage stability.

Do you cook chicken before freeze-drying?
Before chicken can be freeze dried, it must be fully cooked, then diced or chopped into small pieces. The cooked chicken is then frozen to its triple point, which is the lowest temperature where water can exist in both a liquid and a solid state. Most facilities rely on a freeze-drying machine to accomplish this step.
What is the shelf life of freeze-dried food?

Because 98-99 percent of the moisture in food being freeze-dried is removed during the process, it has a shelf life of usually 25 years or more.
Can you freeze dry uncooked pasta?
Sure you can! Most people don’t bother to freeze dry pasta because it has an almost two-year shelf life in the package, but it can come in handy if your dry pasta is reaching the end of its shelf life or if you are running out of storage space. Freezing it can be a great option.
