If boiling isn't the planned cooking method, potassium may still be reduced by slicing or cutting potatoes into small pieces or grating them and soaking them in a large amount of water at room temperature or warmer for greater potassium removal.
Does soaking potatoes reduce potassium?
While researchers found that neither soaking a fresh raw potato or normal cooking achieved a sufficient reduction in potassium, a soaking procedure performed after normal cooking leached up to 70% of the potassium (final values of under 130 mg/100 g).
How do you remove potassium from food?
Boiling certain foods can lower the amount of potassium in them. For example, potatoes, yams, sweet potatoes, and spinach can be boiled or partially boiled and drained. Then, you can prepare them how you normally would by frying, roasting, or baking them. Boiling food removes some potassium.
Does blanching potatoes remove potassium?
A new study in the Journal of Food Science explored the effects of leaching and boiling on levels of potassium and other minerals in potatoes and found that boiling cubed or shredded samples reduced potassium levels by 50 percent and 75 percent, respectively.
