- v. an increased colourless carotenoid content;
- and/or
- vi. an increased α-carotene content;
- when compared to a Dunaliella alga, or extract thereof, which is grown or cultivated under natural light or white light conditions. 2 A powdered Dunaliella alga, or extract thereof, comprising:
- iv. an increased 9-cis β-carotene content and/or
- v. an increased colourless carotenoid content;
- and/or
- vi. an increased α-carotene content;
- when compared to a Dunaliella alga, or extract thereof, which is grown or cultivated under natural light or white light conditions.
