Table 4.
Calculated molar ratios of anti-nutrients (phytates, oxalates) to minerals (Ca, Fe, Zn) of oat grains.
| Oat Varieties | (Phytates: Ca)1 | (Oxalates: Ca)2 | (Phytates: Fe)3 | (Phytates: Zn)4 | (Phytates∗Ca: Zn)5 |

| Yellow | 0.37 ± 0.00a | 0.74 ± 0.00a | 7.60 ± 0.15c | 13.73 ± 0.10c | 15.08 ± 0.25d |
| White | 0.38 ± 0.00a | 0.52 ± 0.00b | 8.49 ± 0.03b | 15.06 ± 0.08b | 16.53 ± 0.13c |

| Goslin | 0.16 ± 0.00d | 0.23 ± 0.00d | 9.07 ± 0.02a | 13.68 ± 0.07c | 35.05 ± 0.21a |
| Soresi | 0.23 ± 0.00c | 0.25 ± 0.00c | 9.05 ± 0.05a | 13.79 ± 0.08c | 25.23 ± 0.14b |
| Mean | 0.29 ± 0.02 | 0.39 ± 0.05 | 8.51 ± 0.15 | 14.78 ± 0.41 | 23.54 ± 0.93 |
| CV | 32.5 | 59 | 7.1 | 11.6 | 34.3 |
Means not followed by the same superscript letters in each column of the oats are significantly different (p < 0.05) from each other. Notes: 1mg of phytates/molecular weight of phytates: mg of calcium/molecular weight of calcium; 2mg of oxalates/molecular weight of oxalate: mg of calcium/molecular weight of calcium; 3mg of phytates/molecular weight of phytates: mg of iron/molecular weight of iron; 4mg of phytates/molecular weight of phytates: mg of zinc/molecular weight of zinc; 5(mg of calcium/molecular weight of calcium)∗(mg of phytates/molecular weight of phytates)/(mg of zinc/molecular weight of zinc).
