Chlorella marketed by Nutriphys® comes from the best producers in the world. The cultivation and production of chlorella pyrenoidosa is systematically and strictly controlled from one end of the process to the other in order to guarantee a high quality product.
Because to develop in an optimal way and allow the obtainment of C.G.F. (chlorella growth factor), chlorella pyrenoidosa requires ideal natural conditions: intense sunlight, open-air cultivation in a low-polluted environment and good climatic conditions. Such conditions exist in some tropical and subtropical regions, such as Taiwan.
Different types of cultivation
Some producers only grow chlorella in indoor tanks. Although it is easier to maintain a constant cultivation this way, they lose one of the key ingredients in CGF’s production… sunlight.
Indeed, CGF is produced during photosynthesis. By choosing a chlorella pyrenoidosa grown outdoors, Nutriphys® ensures and guarantees a higher concentration of growth factor (CGF).
Our chlorella pyrenoidosa is fed by high purity mountain water and is grown in large open-air ponds. And to ensure purity and quality, these crops are carefully monitored during growth and post-harvest. Similarly, a certification has been introduced to guarantee the standardisation of strains.
Cultivation of chlorella pyrenoidosa in 7 stages
The cultivation of chlorella pyrenoidosa requires a well-established and scientifically controlled production process.
The cultivation begins in the laboratory under very strict conditions (light, temperature, water purity, nutrients, presence of CO², etc.), with cultivation of the best chlorella strains in a nutritious medium, the composition of which is kept secret.
A week later, the chlorella divided sufficiently (every 20 hours each mother cell divides into four daughter cells) to be placed outdoors in nutrient-rich cultivation ponds for a period of 7-10 days.
Thanks to the rapid multiplication of cells, the production is transferred to larger basins, where it is continuously stirred. The water in the basins is constantly renewed and crop checks are carried out regularly. The transfer process is repeated three times, each time in larger reservoirs.
At the end of the cultivation, when the density is optimal, it is the harvest. The basin is emptied and the water containing the cells is transferred to centrifuges that select the best, i. e. heaviest, cells. They are then rinsed several times with clear water to remove all impurities. Finally, all water is removed by filtration and centrifugation.
Part of the production is directed to a machine which, thanks to hot water, extracts the cell nucleus to make a concentrate called CGF.
The desiccation process of the seaweed continues with spray drying, an exclusive vacuum drying technique. This ultra-fast, high-temperature spraying technique converts the liquid concentrate into powder.
Because chlorella decomposes easily, it is necessary to cool the cells gently and then dry them as quickly as possible. Spray dry is the most appropriate method because it preserves nutrients and chlorophyll while attaining a sufficient temperature to kill pathogenic organisms.
Le produit obtenu est très stable, avec une bonne conservation des contenus en pigment, en protéines et en vitamines.
Enfin, l’algue est bombardée d’ultrasons afin d’éclater la membrane cellulaire, procédé jugé plus performant que le « Dino-mill ».
Un ultime contrôle de qualité est effectué avant de parvenir au stade de la fabrication des différents produits dérivés (comprimés, extraits, boissons, aliments).
The product obtained is very stable, with good preservation of pigment, protein and vitamin contents.
Finally, the algae is bombarded with ultrasound to break down the cell membrane, a process considered to be more efficient than the “Dino-mill”.
A final quality control is carried out before reaching the stage of manufacturing of the various by-products (tablets, extracts, drinks, food).
The production complies with very strict guidelines, which prohibit the use of pesticides and chemical fertilizers.
Only such a manufacturing process can guarantee a completely natural production of chlorella pyrenoidosa.
