  • How To Freeze Dry Green Beans?


    When you need some green beans, just grab them from your pantry and cook. Freeze-drying can help preserve freshness, nutrition and taste for a long time. It is a way to turn the food back in time when it is not available in the present, like when green beans are out of season.
    The process of freeze-drying the green beans is simple. First, the green beans will be frozen and then put in a vacuum. The vacuum will take the moisture out of the green beans and make them dry and lightweight. As a result, the dried green beans will last for years if kept in the proper condition.
    You can prepare freeze-dried green beans for eating after defrosting. You will find the texture and nutrition remain nearly the same as the original. You can use it just like any fresh green beans in your dishes.
    Freeze-dried green beans also can be added to your other uncooked foods. For example, you can use them in a smoothie. Just defrost them and add it to your other ingredients for mixing. Imagine a delightful smoothie described as having the texture and taste of green beans, but that's exactly how it would be. You could also add freeze-dried green beans to your tuna salad, stirring it with the tuna, mayonnaise, Salt and pepper, and capers.

    Understanding Freeze Drying

    Freeze drying technology, also known as lyophilisation, is used to preserve many types of perishable foods. It involves three stages: the freezing, the primary drying (sublimation) and the secondary drying (adsorption). Food structure, nutrients and taste are retained better after freezing drying than after traditional drying process. It is why freeze drying is preferred as a method to preserve foods such as green beans.

    Equipment Needed

    To freeze-dry the green beans you find at the grocery store, you need a freeze dryer. It is possible to give freeze-drying a try with a conventional freezer, but anyone who has tried these methods understands that the results are typically less successful. A conventional freezer can’t maintain a proper vacuum, which is necessary for the sublimation to occur. If you are a freeze-drying food enthusiast, investing in a home freeze dryer will help you successfully freeze dry different items, meeting all of your needs.

    Preparing Green Beans for Freeze Drying

    1.Fresh Green Beans:

    Choosing green beans in the supermarket can be simple. For the firmest green beans and sweetest flavour, choose fresh young green beans. Avoid green beans that are wilted or showing signs of overmaturity, such as yellow spots or off-colour areas.

    2.Wash and Trim:

    rinse the green beans under cold water and discard any beans that are brown, stained or look dried out. Trim both the top and bottom, and remove any strings.

    3.Blanching (Optional):

    Blanching preserves the beans’ colour, texture and nutrient content. To blanch, boil the beans for three minutes, then plunge into ice water to halt the cooking process.


    Place the blanched (or unblanched, if you skip the blanching step) green beans in a single layer on a baking sheet. Freeze until solid, several hours or overnight. This makes the freeze-drying process faster and more even.

    Freeze-Drying Process

    1.Load the Freeze Dryer:

    If your green beans are frozen solid, then you are ready to load the freeze dryer. Fill the trays to the brink, but don’t overfill. You want to make sure everything is evenly dried so spreading them out single file is ideal.

    Phase 2:

    2.Get the Freeze Dryer Running:

    Plug in and run the freeze dryer according to the manufacturer’s directions. The total drying time is about 24 to 36 hours, depending on how much food you are drying and what type of food it is.

    3.Testing the Depth of Dryness:

    Take off a few beans, and when they reach room temperature, test them for dryness. If the beans feel dry and brittle, you’re done. If they feel chilly or if you detect even the slightest moisture, give the beans a few more hours of drying.

    Storing Freeze-Dried Green Beans

    When the beans are thoroughly dried, put them in airtight containers or mylars with oxygen absorbers. Label and store in a cool, dark place.

    Rehydrating and Using Freeze-Dried Green Beans

    If you’re using the freeze-dried green beans, just soak them in warm water for a few minutes until they plump up to a texture similar to fresh green beans, and you can use them just as you would use fresh in your recipe – in soups, stews, casseroles or as a side.


    Consume Now:

    Your cheese is now ready to be used! Excellent for melting on top of other dishes or mixing into recipes that call for the cheese’s wetness, such as casseroles or sauces.

    Cold Soak for Snacking

    Cold Water Soak: For a crispy munchable type cheesy snack or even use it in recipes if you would like your cheese crumbly. Soak it in cold water.

    More Soaking Time: This one takes a little longer, giving the cheese time to soften; 20-30 minutes or to desired texture.

    Drain and Serve: Hydrate to your taste and drain any excess water. The cheese is ready to eat plain or as an ingredient in a cold dish, salads and so on.

    Tips for Best Results

    Play with Soaking Times: Some cheeses will need longer to rehydrate to your liking than others.

    Change Water Temperature: Warm water will hydrate cheese quicker and is preferred for cheeses that will be melted or used hot. Cold water is preferable for snacking or cold use.

    Storage Post Rehydration: Rehydrated Cheese is best enjoyed immediately, but if you have a few days you can keep it refrigerated but beware that this will reduce quality and safety.
