JPS6121067A - Preparation of sandwich-shaped paste food - Google Patents

Abstract

PURPOSE:To prepare a sandwich-shaped product resistant to the interlaminar peeling, easily, by extruding raw sheets of a pastry product through a three- laytered nozzle to obtain a laminated sheet, heat-treating the sheet, and introducing into a vacuum chamber. CONSTITUTION:A raw sheet of a pastry product is extruded through a three- layered nozzle to obtain a three-layered laminate, which is heat-treated and introduced into a vacuum chamber. When the sheet is taken out of the chamber, the top and the bottom layers are pressed together by atmospheric pressure, and the intermediate layer (e.g. cheese) is impregnated into the rough surfaces and the pores of the top and the bottom layers to effect the integration of the layers. Three layers are bonded firmly together forming a laminate resistant to peeling. The objective sandwich-shaped paste food can be prepared by cutting the laminate to the size convenient to take.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a method for producing a sandwich-like pastry product in which cheese or the like is sandwiched between the two.

Sandwich-shaped paste products can be made by forming a three-layered nozzle into a raw sheet of sandwich-shaped paste products, as is known from the molding equipment for patterned kamaboko and cheese-filled kamaboko (Utility Model Publication No. 59-680fJO, Utility Model Publication No. 56-37595). It can be easily recognized that a three-layer kneaded product can be produced by subjecting the product to a heat treatment and cutting it appropriately. However, when actually manufactured, it was found that the three layers produced were due to the displacement of the interface due to the difference in the expansion coefficient of each foreign substance during heat treatment, and the presence of an air layer at the interface (which is always present during extrusion molding). The paste product peels off immediately and cannot be used as a commercial product. Therefore, the present invention solves the above-mentioned problems by placing the material in a vacuum chamber after heat treatment.

In other words, the three-layered cheese is laminated and heat-treated, and the completed food is placed in a vacuum chamber. After that, when outside air is released, the upper and lower layers are pressed by atmospheric pressure, and the middle layer of cheese is pressed against the rough surfaces and gaps between the upper and lower layers. The three layers stick together and will not peel off. It is then cut into bite-sized pieces.

As mentioned above, the method of the present invention can be commercialized by adding a simple method of placing a sandwich-like dough product, which is easily peeled off, such as a combination of cheese and a pastry product, into a vacuum chamber after the conventional manufacturing process. It is something.
