METHOD FOR THE PRODUCTION OF GELATIN OF MARINE ORIGIN AND PRODUCT THUS OBTAINED

摘要

The invention relates to the production of gelatins from the skins of marine animals and residues of connective tissues from fasciae and muscles by means of several production stages. After washing the skins and/or connective tiss ue several times by strongly shaking them in a cold sodium chloride solution, they are treated with a diluted alkali and then neutralized and washed with water. Treatment with organic acid is of fundamental importance. The use of acetic or lactic acid may be of interest to obtain high rheological properti es and yields. After washing, the gelatin is extracted in water by means of hea t treatment. Subsequent drying is performed by means of heat, spraying or lyophilization. Several compounds are added to this proteic material to form the final product or gelatin.
