Abstract

No significant differences were observed in the relative bioavaila­bility (R.B) of calcium among the studied sources of calcium. Organic sources such as calcium and calcium lactate had the highest (R.B)104%, while calcium sulphate gave 102.7% and the supplement gave 102.4% R.B. compared to calcium carbonate (100% absorption). These data suggest that calcium carbonate and calcium sulphate may be considered as a good sources for bread fortificat. Calcium was equally well available from all studied calcium sources , This is based on the results and status of calcium femur content and calcium absorption. Meanwhile, calcium sources had no effect on the rheological properties of studied doughs.
