Abstract: In a process for producing an edible roe-like multilayer spherical structure composed of at least two layers including an inner layer and an outer layer occluding the inner layer, which comprises a step of synchronously discharging at least two edible materials through a multi-tubular nozzle having at least two different passages including an inner passage and an outer passage surrounding the inner passage and a step of chemically gelling the resulting multilayer spherical structure with a metal ion acceptable for human intake, the outer layer in said resulting multilayer spherical structure being chemically gellable with said metal ion; the improvement wherein(i) said at least two edible materials are at least two edible aqueous sol materials having different properties of being chemically gelled with said metal ion, and(ii) among said edible aqueous sol materials, a material forming the inner layer is convertible to a softer aqueous gel than a material forming the outer layer or is present as an aqueous sol
