A third trial using 10 g seeds and about 150 mL of acetone yielded 170 mg malate material. An improvement, likely due to the increase in solvent and so there may be more than 1.7% in them. We also squeezed the seeds mush while sodium carbonate wet, this also might have helped.

A interesting observation is that the magnesium sulfate loaded acetone drying step, or rather a loaded acetone that is as dry as possible, seems to be essential for clean yields. In fact, the mg sulfate salts turns dark brown and the loaded acetone turns light yellow. Without this step, while MASAing clouds do form but there is little clearance and precipitation.
