The invention concerns a method for producing an aqueous albumin solution from a starting albumin solution which contains stabilizer molecules which are capable of occupying binding sites of the albumin, wherein in a method for increasing the albumin binding capacity (ABiC) for other molecules, at least a portion of the stabilizer molecules is removed from the albumin of the starting albumin solution and separated from the starting albumin solution. To carry out such a method, by means of which a stabilized commercial starting albumin solution can be prepared in a manner which is simpler, faster, cheaper and in a manner which is gently on the albumin by removing the majority of the stabilizers and increasing the albumin binding capacity, the method comprises steps in which the starting albumin solution is brought into contact with a solid adsorption material the affinity of which for at least a portion, preferably all of the stabilizer molecules is higher than the affinity of the albumin for the corresponding stabilizer molecules, and the albumin is separated from the adsorption material; wherein the method is carried out at a pH of >3.
