Abstract: There are described freeze-dried food products which have porous structure with fine texture than those obtained by conventional processes to give smooth melting in mouth and a process for preparing the freeze-dried food products. According to the process, raw materials for the food are made into a form of aqueous solution or paste, emulsified, made into semi-frozen state by cooling the emulsion, freeze-dried by further cooling in a mold, and then subjected to freeze-drying treatment.

Abstract: A method of producing a pressurized gas-entrapping candy is disclosed, which candy releases the gas to generate pleasant sound in mouth, as it melts therein. The candy is produced by heating a mixture of raw materials and water to dissolve the mixture and to condense the same, forming fine air bubbles therein, cooling and shaping to convert the condensate to candy pieces of a desired form, dipping the shaped candy pieces into liquid nitrogen, taking out the candy pieces therefrom to put in a pressure vessel, charging into the vessel an inert gas under pressure, and heating the vessel to cause a partial melting of the candy piece and to entrap the gas in the candy piece.

Abstract: A method of producing a pressurized gas-entrapping candy is disclosed, which candy releases the gas to generate pleasing sound in mouth, as it melts therein. The candy is produced by heating a mixture of raw materials and water to dissolve the mixture and to condense the same, cooling to solidify the condensate, crashing the solidified mass into particles, charging the particles in a mold to press the same for pre-shaping into a desired one, charging the pre-shaped piece into a pressure vessel, charging an inert gas under an increased pressure and heating the pressure vessel to cause a partial melting of the particles constituting the pre-shaped candy piece, and to entrap the gas in a candy piece which has finally no pore in its outer surface.
