摘要: The invention relates to a method for producing an antioxidant composition from lignin, lignin liquor or black liquor which comprises contacting the lignin, lignin liquor or black liquor with an oxidizing agent, wherein said contacting is carried out in alkaline conditions and at a temperature above 160 °C, wherein when the oxidizing agent is oxygen, a gas mixture comprising oxygen or an oxygen-generating compound or composition, then the agent is added so that the oxygen partial pressure is below 0.3 MPa. The invention also relates to the antioxidant composition obtained by the method of the invention and to the uses thereof.
