A basic substance that can be efficiently absorbed into a living body to exhibit sufficient physiological activity and can be used without complicated processing steps in the production of foods, cosmetics, pharmaceuticals, feeds, and the like. To provide a composition containing a bioactive protein and sophorolipid, and a method for producing the same. The basic physiologically active protein concentration is 0.001% to 10%, more preferably 0.01% to 0.5%, and the sophorolipid concentration is 0.01% to 10%, more preferably 0.1%. By controlling the concentration ratio of basic bioactive protein to sophorolipid to 0.001 to 100, more preferably 0.01 to 5, pH 3 to 8, more preferably pH 5 to 7, A complex having a particle size suitable for absorption into a living body and a tertiary structure of a basic physiologically active protein can be formed.
