Total phenolics (y)∗ | 0.129 ± 5.3 × 10-03 | 0.148 ± 0.3 × 10-02 |
Protein-precipitating phenolics (x)∗ | 0.089 ± 1.7 × 10-02 | 0.135 ± 4.4 × 10-03 |
Protein-precipitating capacity (%) | 68.992 ± 0.962a | 91.121 ± 1.372b |
∗x and y are the slopes of the curve (mg phenolics precipitated/mg plant samples) representing the protein-precipitating and the total phenolics in the sample respectively. Different letters across the protein-precipitating capacity (%) row indicate significant differences (P ≤ 0.05) between the protein biding capacities of the extracts from the two sources as separated by the Student t-test (n = 3).
