Organic sea buckthorn powder | BERTRAND

Cryogenic grinding is used primarily when grinding at room temperature would lead to problems. This would be the case with the sea buckthorn berry due to its relatively high oil content. And since the berries already are shock frozen from the harvesting process, cryogenic grinding eminently presents itself to the production of sea buckthorn powder.
