METHOD OF PRODUCING OVOMUCOID Russian patent published in 2012 - IPC C07K1/14 C07K1/30 C07K1/34 C07K1/36 C07K14/81 

FIELD: chemistry.

SUBSTANCE: chicken egg albumin is mixed with an equal volume of a mixture 0.5 M aqueous trichloroacetic acid and an organic solvent in volume ratio 1:1.8-2.3. The formed residue is separated by filtering at 0-5°C. The filtrate is then mixed with an organic solvent in volume ratio of the organic solvent to the filtrate of 3-3.5:1. The supernatant fluid is then removed by decantation at 0-5°C. Low-molecular impurities are removed from ovomucoid through ultrafiltration. The ovomucoid is lyophilically dried. The organic solvent used is a mixture of ethanol and acetone in volume ratio 40-65:60-35.

EFFECT: high output of ovomucoid and high degree of purity.
