It would be great if we could get up arround the 85% extraction without any further cost. The theory is simple and i have seen this over many years as a chef. the cell contains liquid, freezing it makes it a solid and the liquid expands and ruptures the cell walls, easy!! well maybe. if somone in production of algae could maybe try this and get back on how it went. anyone else can try this buy freezing any organic matter and seeing what happens. Or just think about the last time you left a drink in the freezer and it exploded. same idea.
