Cognis: Betatene natural mixed carotenoids

Betatene® natural mixed carotenoids contain several carotenoids derived from Dunaliella salina algae that are not only popular with consumers, but also well investigated by the scientific community. Betatene® provides a unique combination of important carotenoids that are found in many fruits and vegetables.
• Betatene® contains beta-carotene, alpha-carotene, lutein, zeaxanthin, and cryptoxanthin.
• Betatene® supplies several natural isomers (cis and trans) of beta-carotene, unlike the synthetic products, which contain mainly one isomer (all trans).
• The microscopic alga Dunaliella salina is cultivated by Cognis Australia in salt water from the clean and remote Southern and Indian Oceans of Australia.
• The two sites at Hutt Lagoon,Western Australia and Whyalla, South Australia are the world’s largest algae farms with a total capacity of over 1,900 acres (800 hectares).Two sites give security of supply and year round production.
• Innovative, proprietary techniques and rigorous scientific monitoring maximize the growth of these carotenoid-rich algae in a sustainable fashion with positive environmental impact.
• The algae are harvested mechanically, without any chemical additives or solvents.The carotenoids are then extracted and formulated under Cognis total process control using
only natural plant oils.
• Betatene® can be labeled as natural mixed carotenoids (carotenes), natural beta-carotene, algae carotenes, or as provitamin A* (because the human body converts beta-carotene and
alpha-carotene to vitamin A).
• Betatene® is available in multiple concentrations and forms (oil, powder, and tablet-grade beadlets) to meet customer formulation requirements.
• Betatene® has excellent stability. Stability charts illustrate Betatene® products maintain their potency and stability over time. In fact, only a minimal overage is required in most formulations.


The typical carotenoid distribution in
Betatene® 30% is as follows:


                       microgram/gram
beta-carotene      283,500
alpha-carotene       10,500
cryptoxanthin          3,000
lutein                     1,500
zeaxanthin              1,500

Extraction of Nutraceutical Components from Algae Using Supercritical CO2

Nadine Igl-Schmid, Josef Schulmeyr, Andreas Wuzik

Supercritical CO2 extraction pressuresDuring food processing organic or inorganic liquids are conventionally used for separation purposes. While supercritical CO2 extraction is increasingly applied as an alternative at industrial scale, details of processing  are critically important to preserve functional properties of the ingredients, for example carotenoids in nutritional products or dietary supplements. The authors describe algae species which they find best suited for carotenoid extraction and their experience with extraction from sensitive biomass at different pressures with varying outcomes of  supercritical CO2 extraction.
