Freeze-dried blueberries are a great snack and cooking ingredient that many people love. Due to their long shelf life, excellent flavor, and high popularity in the world, many individuals have problems with storing, using, or even making them at home. Wetness and bland flavors can bring disappointment if he or she is not familiar with any other ways to prepare such blueberries. This is why it is important to learn more about the most popular challenges and find real solutions for them. If one wants their freeze-dried blueberries to be perfect despite any external conditions and storage specifics, this guidance is here to help.
How Freeze-Drying Works
Such information is important because in order to solve a problem, one should understand how it appears. When fury food is transferred to a vacuum after freezing it, the ice inside it sublimates directly from solid to gas without any liquid state. This factor affects the product to the extent that it is almost deprived of moisture, but still contains its structure, flavor, and nutrient substances. Poor-quality freeze-drying or incomplete one will make the blueberries maintain the same wetness, causing them to soak and perish. Improper storage will also allow the air moisturizing the room where one keeps them to saturate the snacks, ruining the perfect crispiness. Therefore, it is crucial to understand that wetness is the main problem and the primary cause of many freeze-dried blueberry issues.
Preventing Sogginess and Maintaining Crispness
The most common complain associated with freeze-dried blueberries is that instead of feeling crunchy delight, they can become soft and even chewy. It almost inevitably means the blueberries are exposed o moisture. The solutions mainly focus on proper storing and imply the use of moisture-absorbing substances. Thus, when cooling your blueberries, always put them in an airtight container. Specifically,youshould choose a glass jar that has a solid sealing and can be reliably closed or heavy-duty plastic container. Additionally, you can benefit from including a food-safe desiccantpacket orand oxygen absorber. Both are individual small packets that are designed to soak in all the ambient moisture that may still exist in the container once it is sealed. Thus, once set, close the container and keep it on the shelves of a cool, dark, and dry place. The latter recommendation means a pantry, but make sure to avoid the areas near the stove or a refrigerator. Never put the berries in the refrigerator, as due to the behavior of changes in temperature, opening, and closing the door, the humidity is going to develop inside.
Preserving Color and Flavor
Another frequent complain is when the traditional purple-blue berries lose their color and taste, becoming dull or doing so with time. It normally happens because of due to exposure to oxygen and light, thus making the berries oxidate. Oxygen breaks down all the pigment and flavoring compounds, meant for color and taste. What can be done is secure truly airtight storage. That is especially beneficial for prolonged storage, where it is particularly useful to put your preserved berries in vacuum-sealed bags. All unwanted oxygen is sucked our of the pouch, remirroring the amount of the external atmosphere, retaining a color. The other recommendation is to keep the container in the dark. Light, especially sunlight, could also speed up this process. Reduced exposure to both oxygen and light will preserve the deep purple-blue color and the flavor.
Clumping and separation
A more demoralizing experience is to open your package and discover that all the freeze-dried blueberries have become a single solid block. Only a minimal amount of moisture is needed to cause each individual berry to stick to the others. Fortunately, this is not the end of the world. Applying a bit of pressure can temporarily dislodge them; otherwise, spread them out on a baking sheet and put them in an oven at a low temperature, say 150°F or 65°C, for 10-15 minutes should take care of the rest. Any surface moisture that is causing them to stick will swiftly go away. After cooling completely, place the blueberries back in a cool, dry area in an airtight jar with a fresh desiccant pouch to prevent them from sticking once more.
