Abstract: A method for producing caviar or a caviar-like product from live, mature eggs of fish or crustaceans, wherein the eggs are in a fertile but unfertilized state and have a natural potassium content in the egg plasma, includes: treating the eggs in a saline solution which does not damage the eggs and subsequently treating the live, mature eggs in a solution of water and potassium in a concentration which does not damage the eggs and does not change the eggs' potassium content. The water is deionized prior to the addition of a potassium donor for forming a cationic component in the solution, the solution has a temperature that does not damage the eggs, and the eggs are treated in the solution for a duration of a potassium exposure time until an egg membrane of the eggs obtains a desired elastic stabilization.

Abstract: A method for processing ovulated eggs of an aquatic animal into delicacy foods. Ovulated eggs are harvested without harmful intervention of the aquatic animal. The harvested ovulated eggs are exogenously treated in an aqueous solution by adding at least one signal transduction molecule. Accordingly the membrane of the egg is physiologically stabilized by ovoperoxidase activation. The signal transduction molecule is naturally occurring in the egg cell. The eggs are then preserved.
