Fate of proteins of waste activated sludge during thermal alkali pretreatment in terms of sludge protein recovery
Abstract
Maillard reaction between reducing sugars and amides happened during pretreatment. Over 90 min of TAH at the optimal condition, 67.59% sludge proteins was solubilized. 15.84% soluble proteins broke down to materials with small molecular weight.
