Aloe vera juices are made in one of two ways:
In this method, the entire aloe vera leaf – incorporating the rind, latex and gel – is ground up and filtered using activated carbon to remove the latex compounds called aloin.
The filtering process is known as ‘decolourisation’ or ‘purification’.
Aloe vera latex is bitter tasting, has harsh laxative effects and may be harmful in large quantities. Removing the aloin protects the consumer against these effects.4
With this method, the rind and latex are stripped away before the inner gel is processed into a liquid. Sometimes, the aloe vera gel is also carbon filtered for extra purity (decolourised).
In Europe, pure aloe vera gel destined for use in beverages must have aloin at no higher amount than 0.1 parts per million.5
