When it comes to water content, dehydrated blueberries lose about 90-95% of their water, whereas freeze-dried blueberries remove 98-99% of their water. This significant difference in water content affects their shelf life as well. Properly dehydrated blueberries can last 6-12 months at room temperature, but freeze-dried blueberries can last 10-15 years when stored properly. To achieve long-term storage, freeze-dried blueberries should be stored in mylar bags with oxygen absorbers. For high-quality storage, it is recommended to use Harvest Right mylar bags and oxygen absorbers.
