The present invention relates to particles which include at least one gelled network of at least one gelling polysaccharide in which are embedded at least: one caviar-based food; one agent for reinforcing the gelled network of the gelling polysaccharide and which is resistant to alcohol; and water, preferably purified water. The present invention also relates to an alcoholic beverage (for example vodka) containing said particles, as well as a container filled with said alcoholic beverage.

The present invention provides novel antigens of an allergy to fish, methods and kits for diagnosing an allergy to fish, pharmaceutical compositions comprising such an antigen, fishes, fish eggs or processed products of such fish or fish egg in which such an antigen is eliminated, fishes that deliver such fish eggs or are born from such fish egg, and a tester for determining the presence or absence of a fish antigen in an object of interest. The present invention also relates to polypeptides comprising an epitope of an antigen, kits, compositions and methods for diagnosing an allergy, comprising such a polypeptide, pharmaceutical compositions comprising such a polypeptide, and raw materials or processed products in which an antigen comprising such a polypeptide is eliminated or reduced. The present invention further relates to a tester for determining the presence or absence of an antigen in an object of interest.

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.
