Scientifically known as Hippophae rhamnoides, the bright orange sea buckthorn berry is believed to be native to the Himalayas. Today, however, sea buckthorn is also grown in the cold-temperate regions of Europe and Asia, including the Baltic coasts of Finland, Poland and Germany ¹ .
The extract that we recommend for use in the liposomal formulations we manufacture is basically a concentrated juice extracted from the sea buckthorn berries.
What Makes Sea Buckthorn Extract a Good Preservative?
It has been established that the polyphenols contained in sea buckthorn extracts have a very good antioxidant potential ¹ .
The extracts from the leaves and seeds of this plant also have proven antimicrobial properties ¹ .
Both properties ensure that sea buckthorn is a good natural preservative.
What are the optimal conditions under which it acts as a preservative?
We have found that the sea buckthorn extract that we use in our production works best in a temperature range of 2°C and 21°C. A pH range of 4 - 5 is also ideal for its function as a preservative.
If you store your products according to these recommendations, you can be sure that they will have a long shelf life.
