During cooking process the polysacchrrinic compounds are hydrolysised and degraded into saccharine acids. For neutralization of these organic acids another portion of alkaline is consumed. In this way hemicelluloses dissolved into the pulping liquor. During kraft pulping process about 50% of hemicelluloses and 10% of celluloses are dissolved.

In this process lignin goes into the reactions with the cooking liquor chemicals and split into fragment. These fragments dissolved with the solution and wood disintegrates into fiber. During the kraft pulping process about 80 percent of lignin, 50 percent of hemicelluloses and 10 percent of celluloses are dissolved.
