Analysis of variance (ANOVA) p-values for the second-order response surface model for total monomeric catechins and total PAC content.
| Source of Variation | Total Monomeric Catechins | Total PACs |
|---|---|---|
| Temp | 0.179 | 0.001 |
| Time | 0.439 | 0.099 |
| EthConc | 0.001 | 0.001 |
| Temp × Temp | 0.020 | 0.005 |
| Time × Time | 0.126 | 0.075 |
| EthConc × EthConc | 0.015 | 0.001 |
| Temp × Time | 0.698 | 0.005 |
| Temp × EthConc | 0.112 | 0.026 |
| Time × EthConc | 0.181 | 0.683 |
| Adjusted R2 | 85.2% | 94.2% |
Temp × Temp, Time × Time, and EthConc × EthConc represent the quadratic components of the model; total monomeric catechins included catechin, epicatechin, and EGC; PACs: proanthocyanidins.
