CGF (Chlorella Growth Factor), one of the components of chlorella, can induce interferon and stimulate macrophages in the body's defense tissues and immune tissues.
Microalgae contain a variety of active substances, and current research and development work is mainly focused on PUFA (polyunsaturated fatty acids), polysaccharides, pigments, etc. East China University of Science and Technology has done an outstanding job in using heterogeneous microalgae to produce DHA. my country's current relevant patents, such as 00117546.7 Microalgae health food and its preparation method, mainly include the production and processing of microalgae food.
The active substances in chlorella play a great role in the medical field. For example, PUFA, especially EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), have obvious effects on preventing and treating human diseases such as heart disease, arteriosclerosis, cancer, rheumatoid arthritis, asthma and diabetes. Marine microalgae have the ability to synthesize EDA and DHA, and the content is higher than that of fish oil. It has no fishy smell and can avoid the factor of excessive cholesterol intake. It is not easily oxidized during the process of making it edible and is a good health food.
Microalgae contain a variety of polysaccharide substances, which can enhance the cellular immunity and humoral immunity of humans and animals. Studies have shown that spirulina polysaccharide can significantly enhance the resection and repair of DNA damage caused by radiation and unprogrammed DNA synthesis. It also has a certain anti-mutation function. Chlorella polysaccharide has an effect on ascites liver cancer AH44, AH41c, leukemia L-120, and AIDS. Ascites carcinoma, MethA tumors have shown anti-tumor activity.
Beta-carotene is the precursor of Va and has the effects of preventing and fighting cancer, enhancing human immune function and delaying aging. Currently, most β-carotene on the market is chemically synthesized. With the continuous development of toxicology and analytical technology, people have found that although chemically synthesized β-carotene has high purity and low production cost, the synthesis technology is complicated and the synthetic products contain a small amount of toxic components, which can cause chromosome distortion. The microalgae that produce β-carotene is mainly Dunaliella salina, which can accumulate β-carotene in large amounts, up to 10%, which is much higher than the content in other animals and plants.
Astaxanthin Note 3 is an oxidized carotenoid, which has stronger antioxidant properties than ordinary carotenoids and has the functions of enhancing the body's immunity and preventing cancer. The content of astaxanthin in the cells of Haematococcus pluvialis is very high, exceeding 4% of the dry weight of the cells. It is the organism with the highest astaxanthin content found so far, and is considered to be one of the most promising green organisms. Algae. In addition, it has been found that other individual types of green algae can also accumulate astaxanthin and can be used by people.
