Spirulina dissolves in water, why is it green at first, and then gradually turns blue after half an

The main pigments of spirulina include chlorophyll, -carotene and phycocyanin, and the dark green color of spirulina tablets is a mixture of these three main pigments.

Therefore, after spirulina tablets are added to water, the pigment is diluted and changes from dark green to green.

Chlorophyll and -carotene oxidize or decompose easily and break down quickly into other colorless substances in water. Free chlorophyll is very unstable and sensitive to light or heat; - Carotene is also called pro-va, because its degradation products are two VA, and the properties are also unstable, while phycocyanin is a relatively stable substance, so, after a period of time, chlorophyll and -carotene decompose into colorless, leaving only the blue color of phycocyanin.

Lesser quality spirulina tablets will have some pigments added to give them the dark green color of a high-quality product, but when they are put into water, they will be exposed by a color-changing reaction.

Spirulina flakes are easily oxidized in the air and turn blue after oxidation. This is normal. Therefore, it is important to store spirulina, do not leave the lid open, or the lid is not properly sealed.

Spirulina tablets that have been produced for too long and do not seal well will lose their green color and turn blue.

Therefore, the phenomenon you said is normal, and you can eat it with confidence. It is recommended to chew or swallow. This saves the time for the tablet to disintegrate in the body and is absorbed faster.

Cyanobacteria, also known as cyanobacteria, are a phylum of bacteria that obtain energy through photosynthesis. Species under the phylum Cyanobacteria, also known as cyanobacteria, blue-green bacteria, cyanobacteria or blue-green algae, include fat cabbage, spirulina and other organisms. Cyanobacteria are unicellular organisms that do not have a nucleus, but cells** contain nuclear material, usually granular or reticulated, and chromatin and pigment are evenly distributed in the cytoplasm.

Spirulina is one of the microalgae produced on a large scale and is a rare algae organism with a 3.5 billion year life history and a natural food. Spirulina is a rich and comprehensive organism in nature, spirulina is rich in high-quality protein, linolenic acid fatty acids, carotenoids, vitamins, and a variety of trace elements such as iron, iodine, selenium, zinc, etc.

Here's how to detect spirulina for goodness:

Look at the mark: spirulina has 4 grades: feed grade, food grade, health care grade, and pharmaceutical grade. Regular manufacturers of health food should have the Chinese Ministry of Health's habit "Wei Shi Jian Zi (XX) No. XX and a small straw hat shaped blue health food logo.

Look at the color: put it in warm water and let it stand for 6 hours, the soup color is bright and sky blue: inferior spirulina will be green, which proves that a large number of nutrients are oxidized and the nutritional value is low; If the color of the soup is cloudy, it proves that there are a large number of starch additives, and the nutrients are few and extremely unstable.

pH test: through the pH acid and alkali test, identify the advantages and disadvantages of spirulina, good spirulina should be weakly alkaline after dissolving in water. Alkaline food has been proven by nutritionists from all over the world to be beneficial to the human body, and poor spirulina will be weakly acidic, not only the nutritional content is not up to standard, but also the human body will be affected.

Tableting test: judging the advantages and disadvantages through the tableting technology, the high-quality spirulina tableting technology is mature, the appearance is smooth, it is not stained in the hand, and it is not easy to break; Inferior spirulina has a rough appearance, and it is easy to stain and break when placed in the hand round tomb for a few days.

On the Antarctic continent, the bottom of Lake Bonna grows a flourishing blue-green algae that is several centimeters thick and grows for several years. When light is low, the algae take on a pink color, and this brightly colored pink is phycoerythion, a photosynthesizing auxiliary pigment that absorbs green light more efficiently than chlorophyll. When there is not enough light, it can enhance the ability of algae to photosynthesize; When the light is very strong, the algae color orange again, which is the result of chlorophyllin deposition.

The abundance of chlorophyll plays a role in protecting chlorophyll from the inhibition and damage of bright light, and the algae can use chlorophyll for photosynthesis.

Blue-green algae change their color with the seasons and the intensity of light. When the light is weakened, they are green in color and have a high content of chlorophyll; When light is enhanced, the green color turns red, and the content of red pigment (possibly lutein) increases. As a result, red or green ice and snow algae can often be seen in the snow layer above Antarctic continental ice and perennial sea ice, which is a result of blue-green algae growth.

When scientists measured the temperature of snow with red or green algae, they found that snow with red algae growing had a temperature of 2 3, while snow with green algae growing in the same place, or even in the same pile of snow, had a temperature of 1. This proves that red pigment is good for absorbing more heat energy to increase the temperature of the snow, or helps to keep the snow warm, while green pigment lacks this effect.

Ice and snow algae adjust the temperature of the surrounding ice and snow environment with the help of the change of red and green colors, so as to create more suitable living conditions for themselves, which is also a kind of adaptation.

Many people think that green algae is spirulina, wrong! Chlorella is not spirulina. Here's a closer look at the differences between the two:

Taxonomy of green algae: Chlorophyta, Chlorophyta, Chlorella, Chlorella, Chlorella.

Spirulina taxonomy: Bacteria, Cyanobacteria, Cyanobacteria, Trembling Phyta, Tremor Family, Spirulina spp.

Chlorella grows in freshwater (spirulina grows in saltwater), and from the theory of biological evolution, life is born in saltwater, evolved in freshwater, and grows on land, and freshwater is safer than saltwater. Chlorella is edible for men, women and children. In the process of cultivating green algae in fresh water, it needs to be cyclically stirred, which is expensive to produce, while spirulina does not need to be stirred.

Chlorella is a single-celled plant hypotonic, eukaryotic organism with a nucleus (spirulina is a multicellular fungus, prokaryotes, without a nucleus, and is a simple organism). Organisms that belong to unicellular cells are: humans, animals, plants, and some algae such as green algae, which are genetically related to human cells.

The size of green algae cells is small and molded (spirulina cells are large, 100 times larger than green algae cells, and can be distinguished with a magnifying glass), which can only be seen under a 600x microscope. Green algae cells are similar in size to human red blood cells, but the central ion structure is different, green algae cells are magnesium ions in the center, and human red blood cells are iron ions in the center.

Green algae cells have 3 layers of cell walls (spirulina does not have a cell wall, so there is no need to break the wall) and are very hard and composed of high fibers.

Chlorella growth factor CGF (spirulina does not have this special substance), a unique substance of green algae, is the only one that has this precious and unique ingredient, and no other organism in the world has found an extract with the same biological properties as CGF. CGF is rich in nuclear proteins, ribonucleic RNA, deoxyribonucleic acid (DNA), vitamins, amino acids, polysaccharides, complex proteogies, enzymes, and a variety of plant hormones.

Chlorella is the plant with the highest nucleic acid content.

Chlorella is the most alkaline plant (it produces 3 times more alkaline than spirulina).

Chlorella is the plant with the highest chlorophyll in nature (5 times that of spirulina).

Chlorella contains naturally occurring biotin (spirulina not detected).

Chlorella does not contain iodine (spirulina contains iodine).
