Supercritical CO₂ Extraction
While the Sea Buckthorn is a powerful little fruit, it is also delicate. Extracting its essence can be tricky because even a small change in temperature during the process can have a significant impact on quality and nutrients. For that reason, we utilize Supercritical CO₂ extraction to ensure that every drop of oil, puree, and powder is as pure and potent as possible.
Supercritical CO₂ extraction is a clean, non-toxic process that we use to draw out the essence of the Sea Buckthorn. When the Sea Buckthorn berries or seeds are added to the CO₂ in liquid form, it pulls the oils out, retaining nearly all the vitamins, essential fatty acids, proteins, and other beneficial components. This meticulous process is well worth the work— unlike other extraction methods, it does not cause any heat or chemical damage to the berry because there is no risk of oxidation.
A majority of the bioactive nutrients in sea buckthorn comes in oil forms, including Omega-3-6-7-9, beta-carotene, and vitamin E. And their applications are limited to mainly softgel or ready-to-use oil.
With our advanced microencapsulation technology, Puredia incorporates the functional lipids from sea buckthorn with selected carbohydrates. This leads to the creation of a series of water-dispersible nutritional lipids powder, namely Omega Powder.
This technology provides formulators with more flexibility in formulation design and allows more convenient and innovative applications. The additional microencapsulation shell also protects the easily-oxidized nutritional lipids from oxidation and allows controlled release of the nutrients, ensuring the best bioavailability.
