Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for producing a block of egg eggs applicable to a wide range of food fields such as instant foods such as instant noodles and instant soups, and dried foods.
[0002]
[Prior art]
Conventionally, dried cooked eggs are used as ingredients in instant foods such as cup noodles and dried foods such as sprinkles. In order to automate and manufacture operations such as supply, weighing, and filling of ingredients during the production of dried eggs, various methods have been proposed that are produced using a vacuum freeze-drying method.
[0003]
For example, the production method disclosed in Japanese Patent Laid-Open No. 4-20265 will be described. First, an egg shaped egg is prepared by pouring a filler or a sweetener and further a surfactant added to egg liquid into hot water in the form of a thread or a thin film. Next, the coagulated eggs coagulated in the hot water are collected and placed in a mold to form a plate. The molded product formed into a plate shape is frozen at −40 ° C. to −20 ° C. And the frozen plate-shaped molded object is freeze-dried in vacuum, and is dried to about 3 to 4% of water content over about 10 to 30 hours. Next, the dried plate-shaped molded product is humidified by, for example, leaving it in a humidity-controlled atmosphere to uniformly disperse the water throughout. At this time, the plate-like molded product is humidified to a moisture content of about 4 to 10%. Then, the plate-shaped shaped egg that has been softened by humidification is cut into a certain shape.
Since the method for producing the above-described eggs cuts the plate-like molded product which is softened by humidification and is not broken, there are effects such as easy cutting into a fixed shape.
[0004]
[Problems to be solved by the invention]
However, the method for producing a shaved egg shown in the above-mentioned Japanese Patent Laid-Open No. 4-20265 collects the eggs produced by adding the shaved eggs in hot water and prepares them into a plate shape. Therefore, it takes time to prepare and collect the eggs and the productivity is reduced.
In addition, it states that it can be stored for a long period of time if the moisture content is kept at a predetermined level in order to cut the freeze-dried plate-shaped molded product by humidifying and softening. Is inevitable. Further, rehumidification and softening of the plate-shaped molded product after vacuum freeze-drying makes the process complicated and increases the manufacturing cost.
[0005]
On the other hand, if the egg solution can be formed into a block shape using a container partitioned in advance into small blocks, it is convenient because it can be formed in the size of the egg block that is the final product, but generally the block size is small ( (Normally 10 × 8 × 8 mm), it is difficult to take out the shaved egg block from the container, and there is a problem that handling is difficult.
[0006]
The object of the present invention is to solve the above-mentioned problems of the prior art, simplify the manufacturing process, improve handling and workability when forming into a block shape, and have high versatility that can reduce the manufacturing cost. It is to provide a method for manufacturing a block.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention comprises the following arrangement.
That is, a step of forming a cooked egg solution in which the egg liquid is uniformly dispersed in the sugar liquid by mixing and stirring the egg liquid while heating the sugar liquid diluted with water by adding a sweetener to wheat flour and starch ; a first freezing step of forming a massive oyster eggs blocks frozen eggs solution Ki Ka to -30 ° C~-15 ° C, after the first freezing step, the product temperature was allowed to massive oyster eggs blocks to room temperature After rising to −10 ° C. to −2 ° C., a cutting step of cutting the block of block eggs into block-shaped pieces, a second freezing step of freezing a plurality of pieces of cut egg blocks, and And a step of vacuum freeze-drying a plurality of eggs block pieces.
[0008]
According to the present invention, an egg block composed of a plurality of block-shaped pieces can be efficiently mass-produced by a simple manufacturing process. In addition, since the egg block is finished by vacuum freeze-drying in the final step, it has excellent long-term quality storage and good water absorption and restoration properties.
[0009]
Between the first freezing step of forming a massive oyster eggs blocks freezing and forming a pre-SL or can egg solution, a pre-SL or come egg solution container laid package sheet so as to cover the tray Between the first filling step of filling and wrapping, and between the cutting step and the second freezing step, a plurality of cut egg block small pieces are placed and packaged in a container in which a packaging sheet is laid so as to cover the tray. You may have a 2nd incorporation process.
As a result, when the frozen block block or cut block block piece is taken out from the tray, it is packed with a polyethylene sheet, preventing the frozen block block from adhering to the tray and transporting it easily. It is easy to handle.
In addition, after the first freezing step, the frozen block-shaped egg block may be allowed to stand at room temperature, and the product temperature may be increased to −10 ° C. to −2 ° C., and then the cutting step may be performed.
As a result, when the frozen block egg block is cut into block-shaped pieces, it can be cut without breaking the block shape and can be cut into an arbitrary shape.
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail.
First, the raw material of the eggs of the shaved egg block used in the present embodiment will be described. Mainly chicken eggs are used, but various edible eggs such as quail eggs, duck eggs, butterfly eggs, ostrich eggs, etc. if necessary. Or these frozen eggs can also be used.
[0011]
The preparation of the egg liquid will be described. For example, a liquid egg mixed with β-carotene GA as a pigment is used. In addition, the sugar solution is formed by adding a sweetener such as lactose (lactose), D-sorbitol (glucitol), etc. to wheat flour and starch, and then diluting it with water using a kneader. Is done.
[0012]
Next, the manufacturing process which manufactures an egg block using the said egg liquid is demonstrated.
(1) Preparation of cooked egg The sugar solution is boiled to about 90 ° C to 95 ° C, and a sugar concentration (Brix) of 17% is confirmed. The sweetener is not limited to the above, but the sugar concentration is preferably about 17% as a whole. An egg liquid to which a pigment is added is injected while heating the sugar liquid to prepare an egg. Then, the egg solution is uniformly mixed with the sugar solution to form a dispersed egg, and the kneader is sufficiently stirred to increase the viscosity of the solution having the egg. Heating is continued while stirring, and it is confirmed that the boiling temperature of the eggs is maintained at 90 ° C. or higher, and that the viscosity of the eggs solution is concentrated to a predetermined viscosity. Specifically, it is confirmed that the sugar concentration (Brix) of the cooked egg solution is 16%.
[0013]
