Chlorella (green algae) and Spirulina (cyanobacteria)
In 2 1 century, human beings put forward the slogan of asking microalgae for food and medicine. Therefore, microalgae is recognized as the most ideal healthy food in 2 1 century. Microalgae has attracted more and more attention because it is rich in natural functional components. Dr. T.G. Randolph of the United States said: "Although synthetic products have the same chemical structure as natural substances, they can never replace natural substances, and even get the opposite effect." Physiological active substances of microalgae play an extremely important role in the development of health care products, medicines and functional foods. In addition to Chlorella, there are spirulina widely eaten by human beings. At present, a large number of edible microalgae foods are sold in the market, mainly Chlorella in the world and Spirulina in China.
First, spirulina
Spirulina in algae is a spiral algae called Spirulina. Its volume is about 100 times that of Chlorella, which can be distinguished by naked eyes. It grows in tropical and subtropical alkaline lakes such as Asia and Central Africa. Although the nutrients contained in spirulina can't be compared with Chlorella, spirulina which meets the hygienic requirements is still a new resource food raw material that can be utilized.
Spirulina has a unique spiral shape. De Rubin, a German algae scholar, introduced this strange-shaped algae for the first time in the literature. The name Spirulina should mean "spiral" in Latin. If we want to describe its formal system in plant taxonomy correctly, it should be "Cyanophyta, Chaetoceros, Chaetoceros Spirulina".
Since 1985, Chinese biologists have naturally discovered spirulina in Chenghai Lake, Yunnan Province. Since then, large-scale outdoor culture has been started in many places in China, which has made the development and utilization of spirulina develop rapidly. However, it is not optimistic that due to improper management, water quality in some areas has deteriorated and cyanobacteria have flooded.
Second, the characteristics of spirulina
Spirulina is a multicellular organism.
Spirogyra is composed of several short cylindrical cells, which seem to be vertically connected in a line. We call it a linear body. However, it is not linear. The enlarged picture shows that it is like an elongated spring with a regular spiral shape. Spirulina contains only a small amount of chlorophyll, so it can't carry out full photosynthesis. The size of spirulina filaments varies from species to species. The big one is 300-500 microns long and about 10 micron thick. Compared with 3-8 micron spherical unicellular Chlorella, we can know how big spirulina is. Therefore, spirulina is easy to harvest and has low cost when it is cultured in large quantities, which is one of its great advantages.
Although spirulina is a microalgae, it is a visible organism. Through observation, spirulina can be subdivided into many algae species, each of which has its own characteristics. Spirulina will mutate during its growth, that is, from one algae type gene to another; Even some algae are toxic, which is why spirulina is easy to cultivate, but difficult to purify and ensure its edible safety. The most famous algae species is Spirulina (Spirulina), which is the kind of spirulina food we usually eat. If it is not a variety of pressure plates, the utility will be much lower, or even ineffective.
Third, the difference between Chlorella and Spirulina
Because Chlorella has a good health care effect on human body, China has also invested a lot of manpower and material resources in research and development, but the effect is not ideal. There are two reasons: on the one hand, it is the problem of algae species, and it is difficult to distinguish whether the cultured algae species are high-quality varieties of Sclerotinia sclerotiorum; On the other hand, Chlorella cell wall-breaking technology is not available. The outer layer of Chlorella is very tough because it is wrapped by three layers of cell walls, and the nutrients in it are difficult to be digested and absorbed without wall breaking.
Chlorella is mainly popular in developed countries and regions such as Japan, Europe, America, China, Hongkong, Taiwan Province, etc. Because of its large investment in breeding equipment and high requirements for breeding environment, it needs technical support such as wall-breaking treatment technology. Spirulina is widely used in developing countries because of its low cost.
Chlorella and Spirulina are rich in protein and carotene, which can prevent cancer. The contents of vitamins and minerals in Chlorella are similar to those in Spirulina. The protein content of Chlorella is slightly lower than that of Spirulina. However, some functional components in Chlorella, such as biotin, chlorophyll and folic acid, are much higher than those in Spirulina. For example, the chlorophyll content in Chlorella is five times that of Spirulina, which can be said to be the king of green in nature! Chlorella has a tough cell wall protective layer, while spirulina silk has a cell membrane. The broken wall of Chlorella is a good dietary fiber, which has a good laxative effect and prevents colon cancer.
Chlorella with weak alkalinity is called "medicinal algae" and "bioreactor" of functional substances. More importantly, in recent years, scientists have discovered a special functional substance that spirulina does not have-Chlorella active biological growth factor (CGF). CGF is an active substance with biological reaction modification, and its physiological functions are as follows: it plays an important role in anti-aging, activating human cells and improving cardiopulmonary aerobic function; Activate lymphocytes and increase the phagocytosis of macrophages; Identify and inhibit the growth of mutant cells to prevent the occurrence of cancer; Increase the body's immune function; High concentration of chlorophyll can combine with toxins such as heavy metals and chemical harmful substances accumulated in viscera and tissues and be excreted; Purify the internal environment and restore the detoxification function of liver, spleen, kidney and other organs; Sedate blood pressure, blood lipid and blood trough, and assist in the treatment of chronic diseases such as diabetes, cardiovascular and cerebrovascular diseases; Promote the repair of injured tissues and wound healing; Improve gastrointestinal function, prevent and treat gastric ulcer, promote the reproduction of bifidobacteria and lactic acid bacteria in human intestine, regulate intestinal flora and inactivate pathogenic bacteria.
Chlorella contains natural biotin, but Spirulina has not been detected. The role of biotin has been paid more and more attention by medicine and nutrition. Biotin participates in the metabolism of carbohydrate, protein and fat, and has the functions of preventing premature gray hair, alopecia and decreased vision, relieving gout and muscle pain, and relieving eczema, dermatitis and allergies.
Chlorophyll content in Chlorella vulgaris is 2000-7000mg, much higher than that of Spirulina platensis (800- 1200mg), and its chlorophyll content is the highest in nature. The molecular structure of chlorophyll is similar to that of hemoglobin, and it has a strong adsorption effect on toxins. It is called a "cleaner" for discharging harmful substances from the intestines, kidneys, lungs and blood. Chlorophyll and folic acid can maintain the concentration of calcium in cells and bones, so that middle-aged and elderly people will not suffer from osteoporosis and tooth loss due to the rapid loss of calcium, and can repair damaged gingival tissue. Chlorella is a good product to supplement chlorophyll and folic acid for children who don't want to eat green vegetables and elderly people who have difficulty eating green vegetables.
The CGF functional substance after Chlorella cell wall breaking can improve the regeneration ability of normal cells by more than 25%, produce better cells and regenerate cells, tissues and organs. Traditional Chinese medicine research believes that Chlorella is cool, but the mildest, even people with deficiency and cold can take it.
Comparison between Green Algae and Spirulina
Spirulina (salt water) and green algae (fresh water)
Low alkali content 10 times higher.
Chlorophyll content is 3 times lower and 3 times higher.
Calcium content 1.5 times lower and higher.
Inactivity of vitamin B 12
Cell wall western medicine says: the cell wall of green algae can combine with harmful heavy metals, pesticides and carcinogens in the body and be excreted.
The cell wall treatment is not broken, and it is difficult for patients, the elderly and the weak to digest and absorb. After high-tech wall-breaking treatment, it is convenient for everyone to digest and absorb.
Japan's sales volume ranks first among healthy foods.
The content of C.G.F. is the only content containing C.G.F. in nature.
Western medicine says: C.G.F can renew cells, resist aging, improve cell regeneration ability by more than 25% and produce better cells. Regenerate cells, tissues and organs.
Cell multicellular single cell (the human body is a single cell)
Traditional Chinese medicine believes that cold constitution combined with dampness, abdominal edema, excessive phlegm and candida infection is not suitable. Among seaweed and wheat straw, green algae is cool, but the mildest, even people with deficiency and cold can take it.
▲ 1975, the Japanese government officially legislated to declare green algae as a therapeutic food for chronic diseases.
▲ 1988, the Japanese government's Ministry of Health and Welfare once again legislated to list green algae as a functional food with curative effect.
▲ The first seaweed health food in Taiwan Province Province won the title of "Regulating Immune Function".
▲ Some European countries have confirmed that green algae is a quasi-over-the-counter drug with curative effect.
I hope I can help you. I saw it on some websites of the national general distribution of green medicine green algae, which has more details. I wish you the best of health!
