  • How To Freeze Dry Mango?


    misha

    The exotic and sweet taste of fresh mango can be captured, concentrated and frozen for monthly or annual use at home through the process of freeze drying. Freeze drying an mango stripslimate directly from ice to vapor. The end product of the freeze drying cycle is a lightweight, nutrient-packed and intensely flavoured treat than can be eaten as a crunchy snack, rehydrated for use in recipes, or powdered for virtually any culinary application. Here’s a step-by-step guide to help you start your own freezing-drying mango at home.

    Selecting Your Mangoes

    Much lies in choosing the right fruit; pick mangoes that are ripe and bursting with flavour, firm but without any soft spots or bruises. The best ones are in season at different times depending on the mango variety and place of origin, but in general they are at their best when naturally ripened on the tree.

    Preparing the Mango

    Wash and peel: Rinse the mangoes well, getting rid of pesticides and dirt. Then peel the skin from each one. I like to use a vegetable peeler or paring knife.

    Slice: Detach the mango flesh from the pit and slice it. The size and shape isn’t critical, but thinner slices will yield faster drying time.

    Pre-treatment (Optional): Prevent browning and retain the colour of mango slices by pretreating them in a mixture of ascorbic acid and water or lemon juice and water. Pretreatment is optional but is highly recommended for the best visual and nutritional quality.

    Freeze Drying Process

    To Tray: Lay out the mango slices on the freeze dryer trays. Try not to have them lay on top of each other, as there needs to be sufficient space in-between the slices to allow for air flow so that the drying will be much more effective.

    Freeze: Follow your freeze dryer’s instructions to pre-freeze the slices. Most home freeze dryers have a combined pre-freeze dry phase that is built into the process, but if your machine doesn’t, pre-freeze the mango slices in your fridge freezer until what you’re looking at is more like a piece of cold clay than a frigid piece of fruit.

    Sublimation: Turn on the vacuum pump inside the freeze dryer. Run the drying cycle. It will create a vacuum around the frozen mangoes, then slowly warm them to cause the ice to transition from solid to gaseous state without melting, a chemical process known as sublimation.

    Post-Drying (Optional): After the atmosphere-exchange phase, some commercial units have a final drying step to make sure there is no residual moisture being left behind in the chamber. This step is especially important if you need to store the materials long-term.

    Storing Freeze-Dried Mango

    When the mango slices are fully dehydrated, pack them in airtight containers or mylar bags with an oxygen absorber, and keep them in a cool dark place to maintain freshness.

    Freeze-dried mango can be enjoyed in various ways:

    As a Snack: eat the sliced, delicious cakes from the pack as a healthy, ready-to-hand snack.

    Rehydrate: The freeze-dried mango can be soaked in water for several minutes before use in smoothies, desserts or as a topping for cereal and yoghurt.

    Powdered: Blitz the freeze-dried slices in a food processor or blender to turn them into a fine powder. Adding mango powder can lend a boost of flavour to baking mixes, marinades and drinks.
