PREPARATION OF FROZEN FOOD

PURPOSE:To povide a novel frozen food, by covering a solid material with a frozen layer. CONSTITUTION:A brine solution at -5--40 deg.C is prepared, and water or a liquid containing a sweetening agent, acid, flavoring agent, colorant, etc. is introduced into a freezing tube (a mold) to give a full content. The resultant full tube is then dipped in the brine solution, and the mouth of the tube is opened above the brine surface. Thus, the freezing is started from the inner surface of the feeezing tube. At the frozen layer of 1-5mm. thickness, the unfrozen liquid is discharged to form a hollow part. A solid material, e.g. tartaric acid, sodium hydrogencarbonate or sugar is then introduced into the hollow part, and water is introduced into the upper surface of the solid material to freeze the surface in a short time and take out the frozen food from the freezing tube.
