Abstract
A wood-derived lignin composition is disclosed. The wood-derived lignin composition comprises: —acid-insoluble lignin in an amount of 80-90 weight-% based on the total dry matter content of the lignin composition, wherein the average molecular weight of the lignin is 5000-15000 Da; —carbohydrates in an amount of 1.5-15 weight-% based on the total dry matter content of the lignin composition; —nitrogen in an amount of 0.2-1.5 weight-% based on the total dry matter content of the lignin composition; and wherein weight ratio of oxygen to carbon is at least 0.5 Further is disclosed a method for producing the wood-derived lignin composition.
