Introduction to Algae Dewatering Methods
There are several methods used to dewater algae, each with its own advantages and disadvantages. The goal of dewatering is to remove excess water from the algae while preserving its nutritional content and life force. In this response, we will explore the different methods of dewatering algae, from the least to the most effective.
Methods of Dewatering Algae
The methods of dewatering algae can be ranked from worst to best based on their impact on the algae’s nutritional content and life force. The methods are:
- Spray drying machines used in commercial operations: This method is the worst as it creates oxidative stress, destroys nutrition, and is often used in open pond cultivation, which subjects the algae to water and airborne contamination.
- Centrifuge high-speed spinning: This method is also detrimental as it ruptures and destroys all life in cells, creates oxidation, and cannot be used as a live starter culture.
- Baking (French) pressed: This method is somewhat better as it involves pelletizing and baking, but it can still cause damage to the cells and create oxidation.
- Sun-dried: This method is more natural and eco-friendly but has limited natural processing and can be time-consuming.
- Sieving (Raw Living Spirulina): This method is the best as it is the most natural, causes no damage to cells, and preserves phytonutrients inside cell walls. – Spirulina cells’ integrity after sieving: Virto-Cuccolini’s vibrating sieving equipment takes great care of the product particles, which proved to remain whole after passing through the sieving process and therefore keeping nutrient content unchanged, versus other harvesting methods available in the market.
Comparison of Dewatering Methods
A comparison of the different dewatering methods reveals that sieving (Raw Living Spirulina) is the most effective method as it preserves the algae’s life force and nutritional content. This method does not destroy or alter nature’s package and maintains all the life force (truly alive). In contrast, other methods, such as spray drying and centrifuge high-speed spinning, can cause significant damage to the algae and create oxidation.
Conclusion
In conclusion, sieving is the best method for dewatering algae (Raw Living Spirulina). This method is the most natural, causes no damage to cells, and preserves phytonutrients inside cell walls. It is essential to choose a dewatering method that preserves the algae’s nutritional content and life force to ensure its effectiveness as a dietary supplement.
