Basic Information of Dunaliella

Dunaliella salina is a species of microalgae that inhabits salty and sunny lakes such as Hawaii, Australia, and Israel.

Dunaliella contains cartinoid, which protects cells by preventing damage to the cells in the body by harmful oxygen in our body, and is effective in neutralizing toxic and carcinogens with strong antioxidant effects.

Dunariella also contains a large amount of lutein and zeaxanthin, pigments present in the retina and macula, which are effective for eye diseases.

Zeaxanthin can help the growing number of eye diseases due to modern lifestyles by suppressing damage from reactive oxygen species in the macula and protecting the eye by maintaining the pigment density of the macula.

The business value of dunaliella

Shortsight during growth period due to excessive use of smart phones, long time study etc.
Overuse of office computers, poor eyesight due to stress, and macular degeneration diseases
Eye diseases such as glaucoma and cataracts due to aging

Recently, the demand for eye health care and prevention of eye increased with macular degeneration and cataracts due to aging society

Microalgae are well-known as healthy food and alternative energy sources, and their availability is expanding due to the production of feed for fisheries, medical raw materials, and biological chemicals.
Among the microalgae in the spotlight as health food, microalgae such as Dunaliella Salina produce β-carotene and carotenoid and can be used as natural health food and feed, antioxidant use, and cosmetics.
The zeaxanthin content of the improved dunaliella is 40 times more different from that of the wild dunaliella and 1,000 times more than the corn ingredients. If mass extraction of lutein and zeaxanthin complexes from the improved dunaliella is possible, it can lead the competitivity in natural pigment market for eye health.

※ Development Technology of dunaliella cultivation system through convergence technology development project for small and medium enterprises

March 2017 (Lot#1)~June (Lot#1-Lot#6) a total of six 300L medium incubation studies are conducted. afterwards, demonstration mass culture (5ton)-Reference of picture

- After the medium incubation is conducted in the 300L class culture aquarium, the mass incubation was carried out and the distribution was carried out for 8 days.
-(July-September 2017)

Mass microalgae cultivation technology allows large amounts of microalgae to be cultivated in a fixed space in a short period of time.

Research experiment data of Dunaliella

1. Securing Dunaliella species of marine microalgae with increased content of zeaxanthin and lutein

▶Research purpose ·Identification of the zeaxanthin content of improved species by comparison with marigold and marigold extracts.

▶Research result ·Existing marigold needs new resources to be replaced by foreign companies.
·mp3 obtained in this study
The improved species was deposited with the Korea Center for Biological Resources (KCTC) and was given an accession number KCTC 12990BP.

▶Research purpose ·Estimation of the stability of zeaxanthin and lutein through the stomach, intestines, and tubular simulated experiment

▶Research result ·Invitro pigmentation stability assessment according to pH shows that the pigment content decreases at pH 2.0.

2. Establishing optimal incubation conditions and harvest processes for microalgae containing pigments

·Establishment of optimal incubation conditions for dunaliella enhanced species at the laboratory standard
