Freeze-drying is the very heart of Aboca’s production, the step which makes it truly unique.
Aboca was the first to adopt freeze-drying in the field of extracts from medicinal herbs, in order to preserve the sensory features and contents in active principles, avoiding the use of excipients or technological adjuvants. Freeze-drying consists of quick freezing of the product (at temperatures below -50°C) followed by removal of the liquid component through sublimation, i.e. direct passage from solid to vapour.
Freeze-drying thus affords dry extracts which are 100% natural, without any excipients, solvents, toxic residue, and are concentrated compared to the initial drug.
