Spirulina was one of the first organisms on Earth, with a history that can be traced back more than 3.5 billion years. This microalgae has existed and evolved through many geological periods, witnessing the evolution of life on our planet.
One of the earliest evidence of human use of Spirulina comes from the Aztec civilization in Mexico. Historians believe that the Aztecs harvested spirulina from Lake Texcoco around the 14-16th centuries. They called it “tecuitlatl,” which means “fecal stone” in Nahuatl, and used it as a nutrient-rich food source.
In Africa, especially the area around Lake Chad, spirulina has been used as food by the Kanembu people for centuries. They harvest algae from natural alkaline lakes and dry them into cakes, which are then used in many traditional dishes.
Despite having been used in ancient cultures, spirulina was only really noticed by the modern world in the mid-20th century.
In 1940, a French botanist named Pierre Dangeard reported on the Kanembu people of Chad using spirulina as food. However, it was not until the 1960s that scientists began to further study this algae.
In the 1970s, NASA began researching spirulina as a potential food source for astronauts on long-term space missions. This has drawn the attention of the scientific community and the public to this type of spirulina.
As the studies on spirulina became more extensive, one began to realize its enormous potential in the field of medicine and nutrition.
Spirulina is recognized as a superfood thanks to its high protein content (about 60-70% dry weight), along with many vitamins, minerals and antioxidant compounds. In particular, it is one of the few plant sources that provide vitamin B12.
Numerous studies have shown that Spirulina may be beneficial in assisting in the treatment of many conditions such as:
Spirulina has been used in nutrition programs to combat malnutrition in children in many developing countries. In 1974, the World Health Organization (WHO) recognized spirulina as the “food of the future” because of its enormous nutritional potential.
With the increasing awareness of the nutritional value of spirulina, the industry producing this algae has grown rapidly since the 1970s.
Spirulina spirulina is grown in saltwater lakes or artificial aquariums. Conditions such as temperature, pH and light are tightly controlled to ensure optimal algae growth.
Leading countries in Spirulina production include:
According to recent reports, the global Spirulina market is growing at an impressive rate. It is expected that by 2026, the market value could reach $779 million.
In the context of climate change and global food security, Spirulina is being seen as a potential solution.
Compared to traditional protein sources, spirulina production requires significantly less land, water, and energy. This makes it a more sustainable option in food production.
In addition to its use as a food supplement, spirulina is increasingly used in food and beverage products, from confectionery to juices and smoothies.
Scientists are studying the possibility of using spirulina to absorb carbon dioxide, which contributes to minimizing the effects of climate change.
Despite its many potential, the spirulina industry still faces some challenges.
Since Spirulina has the ability to absorb heavy metals from the environment, it is very important to ensure quality and safety in the production process. Strict regulations and standards are needed to protect consumers.
Despite its increasing popularity, many people are still unfamiliar with Spirulina and how to use it. More educational and marketing efforts are needed to increase consumer awareness and acceptance.
Continued research into new applications of spirulina, including in the fields of medicine, biotechnology and renewable energy, could open up many new opportunities for this industry.
Spirulina's journey from an ancient food to a modern superfood is a testament to the magic of nature and the potential of science. With its long history and outstanding nutritional value, Spirulina is not only an important part of the past but also an integral part of the future of global nutrition and food security.
As we continue to explore and harness the potential of this type of spirulina, it can be seen that Spirulina will play an increasingly important role in solving the nutritional, health and environmental challenges the world is facing. From ancient civilizations to futuristic space missions, Spirulina has proven itself to be one of the most precious resources that nature gives us.
