Abstract Two temperature maxima were found of protein extration using partial autoproteolysis of krill. The extracts obtained at 45‐55 °C show a high content of non‐protein nitrogen, polypeptides and free amino acids, with a low content of thermally precipitated protein. This extract can be utilized as a useable material for direct drying. Otherwise if an extract is used for production of thermally precipitated protein, much better results are obtained at low temperatures of autolysis (6‐10 °C).
