The primary thing freezing does to the living spirulina is stop the cells’ enzymatic life energy.
Freezing is like suspended animation of the nutrients. Freezing whole fresh Raw Living Spirulina does rupture some of the cells; however, it does not destroy the nutrition like heating (powdered). Freezing reduces the nutritional value by approximately 5% immediately upon freezing, and there is roughly a 5% monthly loss. Home freezers go through regular defrost cycles and thus will further degrade the nutrient value of the Spirulina over time, so it is best to consume within three months after freezing.
Note: Most frozen vegetables and fruits in bags in grocery stores have been blanched (dipped in boiling water) to kill all enzymatic life before freezing.
Freezing commercial (algae) involves the pre-rupturing of cells in powerful centrifuges that destroy the cells, which is done due to the location that has grown and the problems with contamination in these watershed reservoirs.
Algae companies store frozen products for months to years before thawing, packaging, and refreezing. During this process, water is generally added to the thawed product to dilute the breakdown of cells during this lengthy processing to give the product a more uniform refreezing effect and to increase profit margins by cutting the original density.
The cell structure stays intact when freezing is done naturally, wholly, and correctly without processing. We have thawed our frozen Raw Living Spirulina, looked at the thawed cells under the microscope in our laboratory, and have consistently seen whole cells. We have also been able to regrow the thawed cell after they were frozen for many months.
We have thawed many other frozen algae products and have found that the cells are not whole and will not re-grow.
Yes, frozen is way way better than any powder.
When you freeze your fresh Raw Living Spirulina at home, you are assured that you are freezing a whole new product in its pure living form. You know the date it was harvested, how it was frozen, and when it was frozen; you are in complete control. Also, I would like to assure you that no processing or expected dilution was done to the product, and there was no thawing or refreezing during transport and storage.
