The Acai berry automatically loses 10% of its nutriments five minutes after being harvested.
It start losing the rest of its benefits gradually 12 hours after the harvest.
For that reason, the acai berry must be quickly flash frozen, pasteurized or turned into powder in less than 12 hours after being collected from palm trees.
This process is necessary in order to preserve the health benefits of the berry which quickly diminish after harvesting.
In fact, the acai berry can lose the total number of its nutriments after 24 hours of the harvest and its taste will turn sour.
When not harvested and handled quickly, marketers of the product tend to add sugar to the berry compounds in order to mask the sour taste. In these cases, consuming the product would not benefit the human body in any way.
