METHOD FOR PRODUCTION OF GELATINE FROM PONDFISH SCALES Russian patent published in 2011 - IPC C09H3/00 

FIELD: food industry.

SUBSTANCE: invention is related to fish processing industry. The method involves scales sorting and washing, treatment with culinary salt solution, thorough washing and fish scale protein substances destruction with subsequent extraction in water, gelatination and drying. Protein substances destruction is performed with the help of a proteoclastic action enzyme preparation - protosubtilin GZKh taken in an amount of 1.0% of the scales weight. Then the scales are filtered, washed with water and extracted, the water: Scale ratio being 1:1, at a temperature of 55-60°C periodically stirred during 2.5-3 h. Gelatination proceeds in a refrigeration camber at a temperature of 2-4°C until solid jelly formation. Then gelatine jelly is cut into 1.5 cm thick slices and dried under mandatory ventilation conditions. Produced gelatine is milled for particle size to be no more than 5 mm, packaged and delivered for storage.

EFFECT: invention enables gelatine yield increase and quality improvement combined with duration reduction and technological process simplification.
