Plant Calcium Content: Ready to Remodel
Calcium (Ca) in plants is primarily complexed with oxalate, phytate, fiber, lactate, fatty acids, protein, and other compounds [2,3]. Although many edible plants are high in total Ca, complexation with oxalate (forming Ca-oxalate crystals) renders it undigestible (Figure 1) [4,5,6], resulting in oxalate being considered an "antinutrient".

Optimal levels of remineralisation for desalinated waters
of the permeate prior to remineralization with calcite beds. In the case of using Ca(OH) 2, the dosage of CO 2 should be doubled. Underdosing of CO 2 produces water with low alkalinity. This implies a low buffering capacity and, therefore, a tendency to easily acidify through uptake of CO 2 from the atmosphere.
