Zamiast ziemniakow

[Blackend]

Kartofel to w całości jeden wielki pasożyt.

Ziemniak wciąż mnie fascynuje 

Wszystko "najcenniejsze" tuż pod skórką... 
A czym dalej w głąb kartofla, tym więcej krochmalu.

The three-dimensional distribution of minerals in potato tubers

The concentrations of most minerals were higher in the skin than in the flesh of tubers. The potato skin contained about 17 % of total tuber zinc, 34 % of calcium and 55 % of iron. On a fresh weight basis, most minerals were higher in tuber flesh at the stem end than the bud end of the tuber. Potassium, however, displayed a gradient in the opposite direction. The concentrations of phosphorus, copper and calcium decreased from the periphery towards the centre of the tuber.
