Top quality extraction from algae

Gentle extraction from algae

In Asia algae are a basic feature in the cuisine there, and are not only used to add flavour but are also popular because of their positive health effects. Nowadays more and more active substances and extracts from algae are extremely popular as food supplements. A large number of these active ingredients can be and actually are extracted using our CO2 technology.

Astaxanthin from Haematococcus pluvialis

The alga (Haematococcus pluvialis) is a green freshwater alga which produces a characteristic reddish colour under adverse living conditions. This pigment is carotenoid Astaxanthin which protects the algae from UV rays and compensates for the lack of nourishment. Due to its antioxidant properties this Astaxanthin is a valuable food supplement. The sensitive substance is extracted using our CO2 extraction process, and high quality oleoresins are formed which are used worldwide. CO2 extraction of most of the carotenoids is however only profitable when pressures of over 600 bar are applied. This is why our exclusive ultra-high pressure equipment is especially suitable for effective extraction of this sensitive pigment.

ß-Carotene from Dunaliella salina

Dunaliella saline is a saltwater algae und an important part of the cuisine in Asian cultures. As it produces large quantities of beta-carotene while growing, it is used in food supplements. Algae carotene is said to possess higher biological activity than synthetic forms and improved antioxidant protection. Concentration of this active substance with CO2 is made possible with our special ultra-high pressure equipmentmore information about D-Factory

Further possible products for CO₂ extraction

Not only valuable carotenoids such as Astaxanthin are extracted by us from algae such as Phaeodactylum, Chlorella, Spirulina or Nannochloropsis, but also special oils and omega-3 fatty acids for food supplement, pharmaceutical or cosmetic industries. We will gladly answer any questions you may have.  

Advantages of our CO₂ production process in the extraction from algae

Especially the oxygen-free atmosphere and exclusion of harmful UV-rays during the entire process ensure that our process is champion when it comes to enrichment of especially sensitive or oxidation-vulnerable substances from marine material and biomasses. We have custom-made extraction units especially for this purpose, which make scaling from research up to industrial ton-scale possible.
