A morphological
Spirulina no non Sheath surface , can not easily be attached to the microorganism , the cell bubbles , floating resistance. Top cells or filaments often not shrill , often not obvious transverse wall , top round cells , the outer wall is not thickened. No sex cells and thick-walled cells can multiply to form blooms .
Cyanobacteria cells in the body without pigment , pigment distribution in protoplasts external pigment area , blue and green. Protoplast inside a colorless central area , like other algae nuclei , but no nucleoli and nuclear membrane , and therefore belong Spirulina prokaryotic plants. Spirulina platensis is a filamentous , helical filaments , no transverse walls , blue and green ; filaments 4 to 5 microns wide , length 400 to 600 microns ; algae silk top cell obtuse, no heterocyst .
History
I believe the first use of Spirulina as food was in the sixteenth century, the Aztecs of Mexico , according to the description Hernán Cortés · soldiers , when they picked spirulina and as chief of the lake from Fernandez Pizza sale . The Aztecs called it the ” special crisp Tel off children ,” meaning stone excrement . Spirulina discovered in the 1960s by a French scientist , but not as a food display purposes. The first large-scale production of Spirulina machine is there in the 1970s established
Spirulina in Chad has a very long history , the earliest retroactive nine centuries Kanem – Bornu Empire. They will still be eating today , drying became known as “Dihé” pizza , used to make broth purposes , and will be sold in the marketplace . Spirulina is like Lake Chad from the collection .
Discovery history
The early 1960s , the French explorer Christopher door when Dr. Dement African adventure, discovery Chad lake in Nimes good animal protein deficient even under conditions of inadequate food vegetables still life physically strong, energetic, health and longevity . After the survey found they often fish floating on Lake Chad dried spirulina food and medical treatment .
2 Reproduction editor
Spirulina reproduction of two kinds:
For the vegetative propagation , including direct cell division ( ie fission ) , groups rupture and filaments produced several ways Hormogonia so on.
Spirulina can be generated for some endogenous or exogenous spores spores to be asexual spores without flagella . Spirulina is sexual reproduction has not yet found .
3 ecological conditions
Salinity: Spirulina a grows in alkaline water , can be domesticated cultured in normal seawater.
Temperature : the optimum range between 30 ~ 37 ℃.
Light: optimum light intensity between about 30,000 to 35,000 lux.
PH : The optimum range between about pH8.6 ~ 9.5.
4 health effects editor
Lower cholesterol
Cholesterol lowering can effectively prevent the onset of heart disease and stroke , spirulina in the Y- linolenic acid can lower cholesterol contained in the body , which can effectively reduce blood pressure and prevent heart disease, reduce cholesterol.
Regulate blood sugar
Spirulina contains nutrient-rich , alkaline foods, nutritional supplements can be changed to give the body acidic , adjust metabolic activity . Jane and Joan Ganoderma with food, can regulate blood sugar, diabetic condition for stability has a significant effect.
Immune system
Natural Spirulina phycocyanin contained within , can enhance immune function of human cells , thereby enhancing our body ‘s immunity and disease resistance.
Protect the stomach
Most patients with stomach hyperacidity are led gastritis, gastric ulcer and other diseases , and Spirulina is an alkaline food , the Spirulina contains high vegetable protein and rich in chlorophyll , β- carotene, these nutrients neutralize gastric acid and gastrointestinal mucosal repair , regeneration and normal secretory function is extremely effective , especially for gastrointestinal patients.
Treatment of Anemia
Iron deficiency anemia is a very common phenomenon, and Spirulina is rich in iron and chlorophyll , these nutrients can effectively improve the human condition of anemia .
5 Nutrition Introduction
Nutritional value
Spirulina is rich in protein , up to 55-75 %, which is three times that of beef , eggs six times , 10 times that of rice .
Spirulina is rich in β -carotene , 15 times carrots , spinach 40-60 times .
Spirulina is rich in vitamins B1, B2, B5, B6, B11, B12, C, E. A wide range of B vitamins , but each with specific physiological functions , the lack of any kind which are likely to cause disease.
Spirulina contains a variety of essential trace elements , calcium, magnesium , sodium, potassium, phosphorus , iodine, selenium, iron, copper, zinc , etc., can cause iron deficiency anemia , zinc deficiency can lead to stunted ; selenium can activate DNA repair enzymes, immunoglobulins , and stimulate the production of antibodies to capture free radicals , reduce toxicity in vivo or resistance to certain metals , inhibiting the carcinogenic effects of some carcinogens . Selenium can prevent altitude sickness .
Spirulina contains chlorophyll A, has its unique clean blood hematopoietic function .
1 gram of spirulina nutrients sum equivalent to 1,000 grams of various types of vegetarian nutrients, is a most nutritious nutrients
Spirulina cell wall is very thin, the thickness of only 40-60 nm, and is constituted by a peptide glucan , easily digested and absorbed degradation .
Spirulina contains high γ linolenic acid , can promote calcium absorption , enhance immunity, prevent metabolic disorders and prevent aging functions. γ linolenic acid is the precursor of prostaglandins , in effect becomes dioxygenase prostaglandins , prostaglandin on the reproductive , cardiovascular , respiratory , digestive and nervous system have a role .
Spirulina polysaccharide , anti- radiation function, and by enhancing the body’s immune system. Also Spirulina polysaccharide can enhance the activity of SOD in plasma , reducing the generation of lipid peroxides , have anti-aging effect .
Effectiveness of the role
1 , to stimulate the rapid growth of the body : Spirulina is rich in lysine , threonine and other essential amino acids, for infants and young children , especially the lack of breastfed infants is extremely important. Rich in minerals and trace elements can effectively prevent nutritional anemia , but also eclipse supplementary source of good nutrition for children , can gradually correct the partial eclipse of bad habits.
2 , balanced nutrition growing youth development : the teenagers in puberty , is much larger than the required nutrients adults , plus learn heavy physical exertion great sport , can easily cause recessive undernourished , stunted growth , memory loss, vision loss . Spirulina can provide adequate and balanced variety of nutrients , is well absorbed .
3 adults maintain a strong effort : significantly accelerate the pace of modern life , diet tends to simple, convenient, frequent ingestion of excessive delicacy , so the accumulation of fat in the body , blood acidic, plus social activities , work stress, rest disorder, no time to exercise, excessive alcohol and tobacco , etc., will result in the body’s metabolic disorders, often feel lack of energy , fatigue, drowsiness , decreased immunity . Spirulina can regulate the body’s pH, chlorophyll can purify the blood , remove toxins and clean the rectum , various amino acids , vitamins, minerals and trace elements contained in the function of internal organs can be enhanced .
4 , anti- aging elderly : The main reason is to generate human aging in the metabolism of a large number of oxygen free radicals, which damage the body strong molecular structure of life , leading to cell function decline and accelerate human aging . Spirulina has a variety of anti-aging substance . Such as β- carotene, vitamin e, γ- linolenic acid , and superoxide dismutase , these substances cleared by antioxidant effects of free radicals , effectively delaying cell aging, while Spirulina is rich in iron, calcium, and easy to absorb of anemia common in the elderly , osteoporosis , hypertension, arteriosclerosis, lumbar and leg pain has a good supporting role in prevention .
5 , weight loss , skin care , beauty : Spirulina is rich in nutrients, 1 hour before taking spirulina, spirulina phenylalanine can suppress appetite, relieve diet brings hunger, suffering malnutrition so that people lose weight while still maintaining vitality. Keep the skin soft and shiny appearance of the fundamental factors are balanced nutrition. β- carotene , superoxide dismutase and γ- linolenic acid on skin physiology to maintain flexibility, eliminate stains , improve skin inflammation effectively .

6 major categories
Spirulina is a total of 35 species belonging to the taxonomic status of Cyanophyta , Cyanobacteria Gang , head chatter algae , algae flutter Branch, spirulina is . Commonly used in the cultivation of Spirulina platensis, Spirulina maxima and Spirulina salt marshes . As health care is mainly consumed Spirulina maxima ( scientific name Arthrospira maxima) and Spirulina platensis ( scientific name Arthrospira platensis). The two species that had previously been divided into Spirulina ( scientific name Spirulina), after sub- section spiral into algae genus, but the habit is still referred to as ” Spirulina .”
Spirulina maxima
Like other blue-green algae , Spirulina maxima cells did not really within the nucleus , compared with platensis, filaments longer, wider pitch , but not as good as the nutritional value of Spirulina platensis high .
Spirulina platensis
Spirulina platensis is usually blue-green, multi- cell type, cylindrical helical filaments , solitary or clustered together students , algae wire diameter 5-10μm. Nearly square cells , cell width 6-8 microns, 2-6 microns long , apex obtuse , spiral count 2-7 . The end is not tapered or slightly thin, the end of the round cells wide , horizontal wall closed slightly constricted , no particles cross the wall . Frond can vibrate and rotational motion , often around a vertical axis as quickly rotate forward crawling. Cell contents even without a true nucleus. Due to the different number of in vivo phycoerythrin and phycocyanin , etc. , and show different body color , such as blue- green , yellow-green or purple and so on. And a delicate cross next door.
7 known origin
The world’s natural spirulina can grow naturally the four lakes , Lake Chad in Africa (Tchad Lake), Lake Texcoco , Mexico (TexcocoLake), Lijiang, Yunnan, China Chenghai Lake and Ordos Hammamet too alkaline lake. After years of publicity, high profile , but the actual remaining Chenghai Lake and Lake still remain too alkaline Hama production, two other lake almost dried up. Chenghai Lake in the vicinity of the affected residents , Chenghai Lake protection has been put on the agenda . Hama no industrial pollution too alkaline lake , abundant groundwater resources , water quality , coupled located at latitude 39 degrees , adequate light and heat resources , which provides favorable conditions for the production of Spirulina .

10 major products
Spirulina products come in many forms , spirulina powder with fruit , edible vegetable sauce mix , tablets, capsules, spirulina extract concentrates and other refined easy access at any time .
Spirulina powder
Spirulina powder is uniformly dark green or blue -green, 100% pure powder no variegated particles may be appropriate to add to many dishes to increase their protein and vitamin content . Spirulina powder soup , bread, salad taste good , not much to give the food consumption of pink dyed dark green . Like many natural foods like spirulina , heat will destroy its rich nutrients , so when making food less heat as possible.
Enjoy spirulina powder easiest way is to add it in the blender or food in your favorite fruit, juice , and consumption from less to more , and gradually adapt. Many who eat it every time you drink eat 10 grams of spirulina powder.
Some useful suggestions :
① Do not wet spoon into his spirulina powder bottle , or a spoonful of spirulina powder directly into the liquid to be added slowly while stirring to avoid condensation.
② dry spirulina powder will absorb moisture, need to tighten the cap after use .
③ without the fridge, but it should be placed in a cool , dry, dark place .
Within 30 minutes after eating spirulina powder , the human body will react , especially since the powder is easy to digest and absorb. Spirulina drinks once or twice , will be able to promptly provide energy and nutrients ( or replace meals between meals ) a day.
Anti-anoxia, anti-fatigue
Product function
Effective in improving the symptoms of stomach , diarrhea and constipation against a variety ;
Prevention and treatment of anemia, carotenoid content is 1.5 times carrots , four times the vitamin B12 content of the liver , the iron content is 23 times the spinach ;

Spirulina tablets and capsules made to make it easier to carry. Most of spirulina tablets containing 200-600 mg, and 400 mg capsules contain or less. Making tablets and capsules , the addition amount of the tableting excipients in the outer sleeve forming or soluble edible film , in half an hour before eating or one hour after meals to tablets or capsules. If certain times of the day feeling low energy , ready to eat a few slices of spirulina, a body generally have a better response two hours later.
Concentrate
Fresh – Liquids: direct extraction of fresh algae , nutrients locked retain activity.
Efficient: cryogenic liquid extraction, retained high activity, absorbed more efficiently . [ 1 ]
11 Identification of the pros and cons
1 . Look mark . For spirulina health food , there must be a formal national health food approval. The information set forth in the product label must comply with the requirements of national standard of health food label specifications . If the list of ingredients , functional ingredients and their contents table , suitable for consumption and taboos crowd of people claiming health functions , taking methods , net content , shelf life, product standards , health permit number , the manufacturer and / or dealer name and The main message address. If any of the major missing information , it shall be questioned. Can be no trademark , no name , no address “three noes ” products, food safety permit access system for national implementation in terms of food have to go through all the “QS” certification mark .
2 . See color . 100% genuine natural spirulina , both powders , tablets, capsules algae powder were tested within the dark green , slightly yellow ( do not look at the surface , but also break apart and look at the cross-section of color ) : pure green Spirulina products , you may have a problem , or shoddy or counterfeit , or a mix of other substances. Because spirulina processed very dry, easy to absorb moisture, the moisture absorption may gradually become green , and easy to spoilage, eat this healthy spirulina not only useless , but harmful .
3 . Smelling odor. Spirulina algae have a special smell or smell of the sea . Without this peculiar smell may not be stored for too long or spirulina algae powder processing of raw materials . However, with the smell of corruption is likely to be inferior products.
4 . Look hardness. Spirulina tablet products for hand breaking it, the harder the more other ingredients spirulina tablets doping , and quality can hand a breaking apart.
5. Tasting. Spirulina has tasted the flavor , usually slightly alkaline taste . If heavier alkali ignorant , is sub-standard . In addition , products made from 100% spirulina , should be relatively sticky mouth .
6. Soluble observation. Spirulina powder or tablet into a glass filled with pure water , and to dissolve, observe the color of water . For quality , water should be green , half an hour later and gradually turns blue .
7 . See packaging. Spirulina nutrients , some with air isolation is needed to save , such as algae blue pigment , carotene. So there must be moisture barrier packaging wet compartment light , the intrinsic quality of the product packaging is the protective layer . Packaging If you do not meet state regulations , likely to cause damage and deterioration Spirulina nutrients. Scientific experiments show that algae blue pigment in direct sunlight for 15 minutes to 50% loss in unsealed condition will basically lost within three months. Therefore, in order to avoid direct contact with light and air , to ensure no loss of nutrients , Spirulina large international enterprises generally use aluminum foil pouch packaging .
In addition , many unscrupulous traders put on the market inferior spirulina seaweed as a sale , consumers need to pay attention to identify. Wakame and spirulina are two different plants, it is easy to distinguish : wakame leaves as big as tea , while Spirulina is a tiny aquatic plant almost invisible to the naked eye , to the aid of a microscope to look 600 times so clear , like the dust was collected .
12 Questions
Quality Protein say
a, high-quality protein to be easily absorbed by the body ( : easy to be broken down for the body to quickly absorb the amino acids) .
b, spirulina high protein content .
c, various proportions of amino acids in the protein content of spirulina is very close to the proportion of the body needs , high utilization . Various human enzymes, the proportion of the various organs of the very demanding requirements of various amino acids . If a particular amino acid deficiency. Other amino acids also play a role and not lost in vain . Its truth is like a bucket from a lot of wood strips , if one of the plates is short , the other the role of boards is also restricted.
Effects on the human body
a, by a variety of human cells. Protein is a major part of cells and tissues , the presence of protein in the form of life . Protein to maintain the growth of cells and tissues , updates and patches , so that the continuity of life .
b, proteins involved in a variety of important human physiological activities. There are a lot of special proteins in vivo function . Such as an enzyme , regulatory protein (immunoglobulin ) , antibodies, peptide hormones. Muscle contraction , material transport by hemoglobin in the blood , etc. to complete protein , a protein which functions can not be replaced by sugar and fat .
c. Protein for the body to provide energy , can produce 4.1 grams of protein per kilo-calories , 18% of adults in the energy supply of the protein.
the role of β- carotene on human health

In addition, vitamin B3 is about 6.4 times soybeans ; β- carotene is about four times the normal levels of carrots ; Spirulina contains about 11 kinds of fatty acids , linoleic acid and linolenic acid which are essential fatty acids ; Spirulina contains major and trace elements necessary for humans and animals , not only contains a lot of iron , but also with protein and phycocyanin organic iron chelated form , which is conducive to absorption, while spirulina has enriched selenium, zinc, ability of iodine.
Spirulina is a very wide range of applications , food, medicines, cosmetics and other fields are applied.
Health Food
Spirulina is rich in high quality protein , vitamins , minerals and other bioactive substances , and its cell wall composed of polysaccharides , easily digested ( 86% digestibility ) , called the best natural green health food .
2 . Fitness and diet food
Spirulina as a diet food in the United States , Europe and other countries has become a trend, the method is 30 minutes before eating or one hour dose of several grams of spirulina can suppress appetite, leaving the reduced food intake , so that neither the lack of nutrition and physical can reduce caloric intake to achieve weight loss purposes.
Of particular importance is that it is rich in iron , and in the diet of women often find iron deficiency .
3 treatments
( 1 ) can be used as anti- radiation damage drugs
( 2 ) can be used for cancer radiotherapy and adjuvant chemotherapy
( 3 ) can effectively reduce blood lipids. A bioactive substances contained within Spirulina – Spirulina polysaccharide and γ- linolenic acid , have the function of regulating the body lipids and prevent atherosclerosis and coronary heart disease adjuvant therapy .
( 4 ) can effectively enhance immunity
( 5 ) Other treatment : Spirulina can effectively prevent the occurrence of cancer . Meanwhile , spirulina for the treatment of diabetes , hypertension , fatty liver, iron deficiency anemia, pancreatitis , ulcer , inhibition of renal impairment has a good effect.
4 Cosmetics
Containing active substances extracted from Spirulina cosmetics , increase skin elasticity , skin moisturizer , wrinkle , freckle and other effects ; can promote skin metabolism, and reduce scarring ; same time as Spirulina cosmetics good permeability , can play the skin surface and deep nutrition and the role of nursing , and is very safe to use on skin without irritation and sensitization.
Earliest Spirulina is used in cosmetics in France . Add spirulina mask, hair care , skin care creams are expensive but very popular. China also has a similar product .
Microcystin
About microcystin (MC) of public health articles , causing everyone’s attention , even to the extent that it was already scared .
The study found that as a liver cancer MC accelerator, a low dose may cause liver damage, which can activate oncogenes body while suppressing cancer genes that make cancer gene inactivation , increase the possibility of cancer nearly 10 times.
In fact, Microcystis in natural waters is widespread , if water quality is good, not too serious contamination or pollution is not , then slow the growth of Microcystis , does not produce a lot of harmful MC.
Only when a large number of untreated pesticides , agricultural fertilizers , such as phosphorus detergent into the water body , resulting in super multi nitrogen and phosphorus content in water to form a water eutrophication case, in the face of a suitable temperature (20 ℃ ~ 30 ℃) , plenty of sunshine , which are conducive to growing conditions when Microcystis , microcystin will quickly multiply in a short time , resulting in a large number of MC.
Since most water bodies are polluted conditions exist , therefore the presence of MC becomes a wide , high-impact natural toxicants . According to the survey found that some areas of surface water as a source of drinking water , even in tap water can also be detected in MC.
Therefore, Shanghai Fudan University, Professor Zhang Shun Yu and other experts pointed out: tap water to eliminate the need to strengthen research microcystin technology and to develop drinking water standards as soon as possible in a limited amount of MC .
Experts point out that prevention MC, the most fundamental is controlled from environmental factors , such as maintaining water flow , manage sewage ban phosphorus pollution caused by eutrophication , and to prevent secondary pollution of drinking water , as long as more than a few MC point is do not worry about the pollution caused by damage to the human body .
As a kind of aquatic organisms , some people worry about whether spirulina is microcystin contamination will not affect food safety ? The experts concluded that Spirulina is safe containing MC will not affect food safety.
This is due to the growth of Spirulina and Microcystis environment is conflicting . Spirulina can grow to survive environmental microcystin ; while microcystin waters can grow , and harvest spirulina really difficult to survive .
Spirulina specializing in research for many years experts have also to be sure.
Experts agree that the current production of large enterprises Spirulina is safe, consumers can rest assured that taking , do not worry about their safety .
Use different populations
Old people
Elderly people taking spirulina, 45% is for a specific disease, 28% used to maintain good mental health , 12% is used as a nutritional supplement. Among those for specific disorders , 22 percent in order to increase blood sugar , 15% in order to protect the eyes, 14% compared relieve constipation .

In addition, long-term use of Spirulina foods can reduce women premenstrual syndrome, female endocrine regulation .
5 Athletes
Spirulina is a basic food for the body to maintain normal blood weakly alkaline, eliminate fatigue effects, to improve the athlete’s endurance , power , and promote athletes to improve physical function had a significant effect .
6 computer personnel
In modern society, let us not hide electromagnetic radiation , especially long-term operation of the computer , people who use mobile phones while Spirulina is recognized as the world’s anti-radiation adjuvant treatment of food .
If the effect is not significant, need to check the following points :
When eating spirulina, whether the case intermittent , or consumption adequacy . (Depending on individual constitution and the environment, taking also vary the amount we recommend taking daily care of about 5 grams a day , taking about 10 grams of rehabilitation per day ) .
Daily diet is inconsistent ( too many acidic foods , tobacco, alcohol , mental stress or irritation ) .
Lack of proper exercise
Some people do not eat spirulina B cards diarrhea , but after eating a brand algae began to diarrhea .
This phenomenon , there are two possibilities, one containing an excess of harmful dinoflagellate fungi, unsanitary ; Second, the quality , but off B algae , dinoflagellates and good quality , causing a better response .
Determine what causes diarrhea because come, there is a simple way is to look after the diarrhea is not a bad effort because of diarrhea caused by unsanitary , can cause people to weakness, even dehydration, but also showed better response although diarrhea , but it does not lead to deterioration of human effort .

This ancient sea creatures , like high temperature (25 ℃ ~ 36 ℃), high alkaline (PH9-11) in the growth environment, many organisms , bacteria difficult to survive in this environment , and spirulina able growth and reproduction. In particular, it is not only the most nutritious , most comprehensive, balanced nutrition is a true champion on the planet , and high light efficiency , adaptability , growth cycle is very short , fast breeding , particularly high yield , artificial breeding efficiency particularly good prospects very broad.
Spirulina correctly handle the relationship between reproductive and environmental conditions
Spirulina farming is the most important conditions of light , temperature, medium and ventilation . PH value of the culture solution , a reasonable supply of depth, flow , exhaust oxygen and nutrients , are an important factor in yield. Therefore , training should be built in pool water quality is good , light conditions are suitable, spacious venue where ; PH value range is 7-11 , preferably 8-9 ; depth of between 0.2 and 0.3 meters ; temperature 18-38 ℃, the most Fortunately 26-32 ℃.
Two Dian choose suitable breeding species
The main breeding species on the domestic and foreign production of Spirulina platensis ( native to Africa Lake Chad ) and Spirulina maxima ( originating in Mexico ) . Huanghua in Hebei Province of algae scientists found suitable for temperate coastal counties grow Spirulina natural variability strain was identified as Spirulina platensis strain 6 (S6); country and from Chad to introduce Spirulina platensis strain 1 (S1); China has also been bred strains and ST-6 Spirulina Spirulina subsalsa . These varieties ( lines ) , can be selected according to local conditions . S6 suitable for growing in northern China where , and salt marshes Spirulina was adapted to high temperatures, sea salt and algae reproduction .
Three Dian from reality , using different farming methods
1 Family farming. You can buy ” Spirulina family culture system ,” also can choose enamel pots ( best all-white ) or crock pot , but can not use aluminum cone . Person- scale farming should be determined by the amount consumed spirulina . If using a 36 cm washbasin , a child needs 12 , while an adult will need around 20 .
2 simple farming. Mainly refers to the equipment is simple, you can make the best pond , as long as watertight on the line. Pool depth 30 cm , the area should be as some large , according to an adult 1.5m2 meter .
3 natural lakes farming. Originally Spirulina grows naturally in saltwater lakes in the original algae, the use of natural lakes farming is the most original , the most economical mode of production . Its equipment requirements are very low , just invest in the fight floods and processing , the lake ‘s fertility can be restored by nature . But because spirulina on light, temperature , PH value, etc. have special requirements , not all lakes can be farmed , but should experiment , research, and select the appropriate reproductive lakes ( such as our Chenghai Lake in Yunnan Province , etc.), for breeding .
4 . Factory farming . Advanced equipment , the grand scale , demanding. Currently, the breeding pool to runway style oval concrete ponds as well ; farming area of 15,000 m2 is best as a unit . Training can be open , but also for closed production . Open Training is a near-natural production methods, the system of freshwater , sea water system , most pools are designed to train circulation , stirring with a mixer , the depth of the liquid culture for 15-25cm, with sunlight as the light and heat sources . Closed production means in a closed bioreactor by means of natural light or artificial light be a breeding factory production of Spirulina .
