hawaiian spirulina: Blue-green algae commonly referred to as Spirulina belong to two species, Arthrospira platensis and Arthrospira maxima, have been consumed by people for their food value for several centuries from pre-historical period. Spirulina was eaten by the Aztecs and different African tribes as an important food component being packed with protein and valuable vitamins. Spirulina is today commonly known as a superfood since it contains nutrients in an unbeaten amount and has other health benefits.
Grown all over the world, the type of environment in which spirulina is grown affects its quality, nutrient density, and potential health effects in a region. In this article, the author discusses the growth area of spirulina, what factors affect its nutritional content, and the most crucial similarities and differences between spirulina from different parts of the world.
The Antecedent History of Spirulina
Spirulina was used by the Aztecs who got it from Mexican lakes particularly lake Texcoco. They called it “tecuitlatl,” which translates as “stone that is edible” in English and it was mostly eaten, though combined with corn to make some sorts of nutritive cakes. Spirulina in Africa has been largely consumed by the Kanembu people of Chad, from where it is harvested from Lake Chad.
This algae has been known for its high protein content and nutrient value, making it a food security staple to the food insecure populations. The new phase of commercial production of spirulina began in the 1970s with the growth in awareness of its nutritive values and health-enhancing properties, which make it to become a common socio-economic production in world’s health foods market.
The Nutritional Value of Spirulina
It is important to know the nutritional value of spirulina in order properly assess the dietary supplement it provides. A typical serving (about 7 grams or one tablespoon) of dried spirulina contains approximately:
- Calories: 20-30
- Protein: 4-7 grams
- Carbohydrates: 1-2 grams
- Fat: 0.5-1 gram
Vitamins: B group of vitamins include; B1 (thiamin), B2 (riboflavin), B3 (niacin), B6, B9 (folate), B12, C, D, and K
Minerals: Calcium, iron, magnesium, potassium, phosphor, sodium, and zinc
Antioxidants: Phycocyanin, beta carotene and other carotenoids
These nutrients enable spirulina to be categorized as a super food since it is packed with nutrients that when added to vegetarians and vegans diets they provide them with a source of protein from plants.
I. Local Development of Spirulina
It has been established that the geographical source of spirulina can often have a considerable effect on its quality as well as nutritional values that are possessed by the product. Here’s an overview of major spirulina-producing regions:
1. Hawaiian Spirulina
Being an island state, Hawaii has excellent spirulina which is grown in warm and mineralized waters. This growth is daylight that gives Hawaiian Spirulina richer nutrients than other spirulinas produced from other parts of the world.
Cultivation Characteristics:
- Climate: It is well known that warm and sunny weather conditions are perfect for plant to grow all year round.
- Water Quality: Fresh, bacteriologically stale water from aquifers replenishes nutrients, thus improving the quality.
- Sustainability: Hawaiian spirulina farms are common and most of them do not use hazardous chemicals in their farms.
Nutritional Highlights: Hawaiian spirulina is high in protein (% of its weight up to 70) and contains a high level of antioxidant including PC and phycocyanin that gives the bluish pigmentation to the product.
2. Indian Spirulina
Spirulina is produced at a large scale in India particularly the states of Andhra Pradesh and Tamil Nadu. The existence of liberal climate and modern techniques of aquaculture fosters the production at large. it comes 2nd in nutrition after Hawaiian Spirulina.
Cultivation Characteristics:
- Climate: For other plants the hot tropical climate provides excellent conditions for this rapid development.
- Farming Techniques: Many Indian farms also employ concrete producers open ponds with superior technology of aquaculture practices to gain best input of water quality and nutrient.
- Certification: Almost all Indian producers availed themselves of such a certificate, which means that spirulina does not contain dangerous chemicals.
- Nutritional Highlights: Spirulina produced from India is well recognized in the world for having a good protein profile mostly containing vitamins and minerals. However, there are customarily differences which are conditioned by particular conditions of farmers.
3. Chinese Spirulina
Spirulina is one of the most popular bio-foods produced in China, especially in the provinces of Xinjiang and Inner Mongolia. The country uses productive agricultural technology for food production. it comes 3rd in nutrition after Hawaiian Spirulina.
Cultivation Characteristics:
- Climate: It is, however, everywhere and many places enjoy particularly good conditions for spirulina production.
- Industrial Farming: Evaluating a vaster scale of operation, controlled environments are applied to improve growth conditions while minimizing the threat of contamination.
- Quality Control: Although, the Chinese government has attempted to better quality standards, customers should buy goods with third party test pass certification.
- Nutritional Highlights: Superiority of Chinese spirulina quality cannot be denied but the quality differs depending on the quality of production. It may provide a variety of nutrient levels depending on growth practices and condition.
4. African Spirulina
Spirulina is grown in some African countries such as, Chad, Burkina Faso, and Tanzania. As a culinary product it is advocated for to help fight malnutrition especially in areas of food insecurity. it comes 4th in nutrition after Hawaiian Spirulina.
Cultivation Characteristics:
- Climate: The taps are found in zone 7 through 11 which are tropical and subtropical regions although water supply is somewhat limited.
- Community Farming: The vast majority of African Spirulina farms are still owned by communities and offer food for their members together with income.
- Sustainability: Use of organic farming reduces the ecological effect on the environment due to a focus on production practices that are safe for the natural environment.
- Nutritional Highlights: Generally African spirulina is a good source of protein and other essential nutrients but depending on the conditions in the region it can be produced the nutrient content may vary.
5. South American Spirulina
Earlier, spirulina was being produced only in limited quantity but now Brazil and Chile have become significant producers of spirulina. The climatic conditions in such regions can improve the quality of the algae. it comes 5th in nutrition after Hawaiian Spirulina.
Cultivation Characteristics:
- Climate: Different kinds of climate, enable different methods of growing crops.
- Emerging Markets: Spirulina production is on the rise across the world, yet it is still incipient as opposed to other areas.
- Research and Development: A few farms participate in projects to enhance environmental factors and characteristics of nutrients.
- Nutritional Highlights: South American Spirulina may contain high levels of nutrients but quality is scarcely stable due to the industry’s phase of maturity.
Variations in Nutrient Composition by Location
What nutrients are present in spirulina changes with the region in which the plant is grown. Key factors influencing these differences include:
Water Quality:
Spirulina’s nutritional value is highly influenced by the mineral composition of water used in its cultivation. For example, Hawaiian spirulina is appreciated for its mineral content because of the aquifer water use.
Growing Conditions:
Environmental conditions such as temperature, exposure to sunlight, and ph all affect the rate of increase as well of the intake of nutrients by spirulina. It was also found that Spirulina cultivated in tropical climates like Hawaiian Spirulina is characterized by enhanced growth rates and maximum content of nutrients as compared to Spirulina grown in temperate zones.
Farming Practices:
Spirulina produced from areas that employ good organic farming methods is healthier due to low content of contaminants and enhanced nutrient value.
Harvesting and Processing:
The techniques of sundowning, drying, and grounding up all affect the level of nutrients retained besides flavour. Fresh Spirulina has higher levels of nutrients, compared to its processed form of Spirulina.
Quality Considerations
While choosing spirulina, people should pay much attention to the quality of the spirulina. Here are several factors to consider:
- Source: It is advisable to be careful on the source of spirulina that you intend to consume. Select those brands that do not hide important information about farming, production and supply chain.
- Certifications: Check whether respective products bear organic certifications or third-party tests for product’s purity and safety. As Hawaiian Spirulina has certification.
- Form: Spirulina comes in the different forms such as a powder, tablets or capsules. Choose the form that fits your dietary requirement and function you intend to use it for.
Spirulina for Health
Regardless of its source, spirulina is linked to numerous health benefits, including:
- Rich in Nutrients: Spirulina is a powerhouse of protein, vitamins and minerals and can be a boon to vegetarians and vegans.
