Freezing is like suspended animation of the nutrients. Freezing whole fresh Raw Living Spirulina does rupture some of the cells however it does not completely destroy the nutrition like heating (powdered). Freezing reduces the nutritional value by approximately 5% immediately upon freezing and there is approximately a 5% loss per month thereafter. 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 3 months after freezing.
Note: Most frozen vegetables and fruits in bags in the 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, (specific to companies such as E3Live, etc.) which are done due to the location has grown and the problems with contamination in these watershed reservoirs.
Algae companies store their frozen product 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 long processing to give the product a more uniform refreezing product and to increase profit margins by diluting the original density.
When freezing is done naturally, wholly and correctly with no processing, the cell structure stays mostly intact. 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 living fresh product in its pure living form. You know the date it was harvested, you know how it was frozen and the time it was frozen, you are in complete control. You are assured that no processing or common dilution was done to the product and there was no thawing and refreezing during transport and storage.
Is your raw spiralina delivered frozen?
We ship our Spirulina fresh (not frozen) in custom coolers with ice bricks to keep the live Spirulina cold but not frozen.
Raw Living Spirulina is delivered to you in its fresh state, not frozen.
Interesting… No mention of what freezing does to the enzymes.
