Chlorella (commonly known as green algae) is a kind of organism that propagated on the earth 540 million years ago. It is a unicellular green microalgae. No matter the great changes in the ecological environment or the invasion of natural disasters, it has not been destroyed, and its stable genes have never changed. It was not until 100 years ago that humans invented the microscope that this creature was discovered by biologist Dr. M.W.Beyernick. The Greek word Chlor (green) and the Latin word Ella are combined to name Chlorella. Because its diameter is only 3 ~ 8 microns, it must be seen with a microscope of 600 times or more, and its shape is spherical, so it is called Chlorella (green algae).

The CGF essence of Chlorella vulgaris accounts for 5% of its own, and it also contains about 60% of protein, 16 vitamins (including B 12), 1 1 minerals, chlorophyll a, chlorophyll b, lutein, carbohydrates, nucleic acids and so on.

The metaphor of the image is: the protein content of Chlorella is twice that of beef and three times that of chicken; The iron content is 50 times that of raisins and 16 times that of pig liver. The content of calcium is twice that of milk; The content of vitamin A is four times that of raisins. Carotene is 100 times that of ordinary plants; Chlorophyll is five times that of spirulina (also known as cyanobacteria); It contains vitamin B 12 higher than that of foie gras. Therefore, Chlorella also enjoys the reputation of "plant nutrients+meat protein". Its nutritional value greatly exceeds that of high-protein foods such as eggs, beef and soybeans.

Chlorella has three layers of cell walls and is very tough. The effective method of breaking the wall is a worldwide problem, which is difficult to crack. Chlorella can live on the earth for more than 500 million years. The key is to have tough cell wall protection, and it is difficult to break tiny green algae cells by conventional methods. Chlorella is rich in various nutrients, which can only be released after the wall is broken and digested and absorbed by the human body. No matter how excellent the quality of Chlorella is, even if it is not processed into a nutritious and healthy product, it is actually difficult to play its role in improvement and regulation.

After more than ten years of scientific research, the ideal method of breaking the wall has not been developed, which makes Chlorella gradually forgotten in China. As a result, spirulina, another species in the microalgae family, has quickly entered the field of vision of algae health care products enterprises because of its low requirements for culture conditions, low cost and no need for complicated wall-breaking treatment. At the same time, in developed countries and regions such as Japan, the United States, China and Taiwan Province Province of China, Chlorella has always occupied a dominant position in the field of health food, and it is recognized as an indispensable and valuable health food in developed countries.
