where, UD: Unit density; BD: Bulk density; ER: Expansion ratio; WAI: Water absorption index; WSI: Water solubility index; PDI: Durability index; L: Lightness; a: redness;
b: yellowness; Parentheses indicate ±1 standard deviation; means followed by similar letters for a given dependent variable are not significantly different at P < 0.05 among treatments. |
