Do you know that acai berry fruit can be processed in two ways? And this is the key for you to know whether the acai product is pure or not.
The first one is the freeze drying method, whenever you want to buy acai supplement, you should always choose acai products which is processed by this method. Because it can ensure the preservation of minerals as well as acai nutrients, and you can be assured that you can get a pure acai supplement.
On the other hand, if the acai berry fruit is produced using spray drying method, maltodextrin can be added as coating to the fruit. You can never buy the pure acai products in this case.
