Strong drugs may have strong side eﬀects. On the other hand, spirulina is a natural food which have been used as food since ancient times. It is thus gentle and harmless to the human body.
The method of its culture and production is also safe and hygienic. Spirulina has been proved to be a safe food through strict toxicity tests by various research organizations.
Outdoor culture pond of spirulina
The production of spirulina consists mainly of four processes, 1.culture, 2. ﬁltration, 3.washing and dehydration and 4.drying.
Spirulina is cultured under the same condition as its original habitat, salt-water lakes, in subtropical area. An alkaline culture solution with nutrition is poured into a wide shallow culture pond, which is stirred by gentle streams. This allows spirulina to eﬃciently carry out photosynthesis and to multiply.
Multiplied Spirulina is in the form of algae. It is then separated from the culture solution through ﬁltration.
3. Washing and Dehydration
Separated from the culture medium and condensed spirulina is placed on vacuum dehydration filter and repeatedly washed with clean water and dehydrated.
The dehydrated spirulina is instantaneously dried with a spray dryer and
made into ﬁne powder.
