Studies on the Availability of Calcium (Report 2-1)

The Relationship between the Utilization of Calcium and Oxalic Acid or Oxalic Salts. (Part 1) Influence of Quantity of Oxalic Acid on Utilization of Calcium

Abstract

The aim of this experiment was to investigate into the influences of pure oxalic acid upon the utirization of a calcium source.
Feeding albino rats with diets containing 0.3% calcium (CaCO₃ was used as calcium source) with 0.5-3% oxalic acid added, we investigated into there calcification.
As shown in table, the same result as in the previous experiment was obtained.
Oxalic acid, in free acid, reduced the utilizaton of calcium when its amount exceeded 1% of diet.
