Abstract
Abstract The present invention relates to granular food products resembling the natural caviar of sturgeon, salmon and other fish, and to a method of preparing same. According to the present invention the product contains an aqueous colloidal solution of proteins, gelatin, ions of alkaline earth metals, polysaccharides capable of forming ionotropic gels when interreacting with the above-said ions, and vegetable tannins, preferably tannides, the products resulting from the interreaction of polysaccharides with ions of metals, and of vegetable tannins with proteins being contained in the membrane or pellicle of the granules.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
140 words
A granular protein-containing food product resembling natural caviar comprising, in granular subdivided form, an aqueous colloidal solution of proteins; gelatin in an amount ranging from 3 to 10 per cent by weight (dry basis); water soluble edible salts of alkaline earth metals capable of forming bivalent metal ions in aqueous solution; polysaccharides in an amount ranging from 0.1 to 5.0 per cent by weight (dry basis) capable of forming ionotropic gels when reacted with aqueous solutions of said edible salts; and vegetable tannins; the product, in granular form, being characterized by having a coating resulting from the reaction of said polysaccharides with said ions and of said vegetable tannins with gelatin and protein on the outer surface of said granules to form a layer, said layer comprising a membrane or pellicle enclosing and containing said aqueous colloidal solution of proteins.
Claim 2
Dependent Claim
