Packaging for freeze-drying strawberries
Due to the loose and porous structure inside freeze-dried strawberries, they are highly susceptible to moisture absorption, oxidation, or flavor mixing. Therefore, packaging materials must have extremely high barrier properties. Aluminum foil bags or high barrier composite films are preferred, as these materials can effectively isolate air
Three drawbacks of freeze-drying strawberries
Although freeze-drying technology can retain over 90% of thermosensitive nutrients such as vitamin C and anthocyanins, it is essentially a physical dehydration process that leads to highly concentrated sugars and calories. The calorie content of 100 grams of fresh strawberries is only about 32 calories
Five considerations for freeze-drying strawberries
When shopping, it is advisable to choose reputable brands and avoid purchasing loose-packed products on the roadside or "three-no" products without a production license (SC). The ingredient list of high-quality freeze-dried strawberries should be as clean as possible, ideally containing only "strawberries"
Four self questions and answers about freeze-drying strawberries
What is the difference between freeze-dried strawberries and regular dried strawberries? Answer: The biggest difference lies in the processing technology. Ordinary dried strawberries are usually dried with hot air or dehydrated with sugar stains, which can damage the cell structure of strawberries, resulting in darker color, harder texture, or more tough texture. And strawberry freeze-drying is carried out in a vacuum low-temperature environment
