Description

Technical Field

[0001] The present invention relates to a method for manufacturing an aggregate food of fine particulate matter such as fish eggs and fish egg-like particulate matter.

Background Art

[0002] Fish eggs such as pollock roe are wrapped in an egg sac. However, if the egg sac is damaged and the fish eggs become scattered, they can be distributed in the market by adopting packaging means such as film bag packaging or bottling in the scattered state. However, it has been proposed since before to make an aggregate of scattered fish eggs into a food that can be distributed by a processing means for applying a coating that replaces the egg sac.

[0003] For example, Patent Document 1 discloses a pollock roe-like formed food in which scattered fish eggs are wrapped with thin fish mince using a twin-screw extruder, subjected to appropriate heat treatment (processing of the mince), and then immersed in water or an aqueous solution of salts to gel only the surface. Patent Document 2 discloses a food in which fish eggs or the like are coated with fish mince, immersed in seasoned vinegar as it is, and the protein on the surface of the mince is denatured to form a film. Further, Patent Document 3 discloses a method in which scattered egg grains are molded using a binder, the molded product is immersed in an aqueous sodium alginate solution, and then immersed in an aqueous calcium chloride solution to form a film of calcium alginate on the surface of the molded product.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The treatment of loose fish eggs (microgranular foods) disclosed in Patent Documents 1, 2, and 3 requires that after once forming them into a formed product (forming treatment by coating with fish paste or using a binder), they need to be further immersed in a predetermined aqueous solution for surface treatment (film formation). That is, a two-step treatment of a forming process for aggregating loose fish eggs (microgranular foods) into one mass and a film-forming treatment of immersing them in an appropriate aqueous solution for gelling the surface is required, and the production is cumbersome.

[0006] Therefore, the present invention proposes a method for manufacturing a novel granular aggregate food that is easy to manufacture and can easily realize the mechanization of continuous production.

Means for Solving the Problems

[0007] The method for manufacturing a granular aggregate according to claim 1 of the present invention is characterized in that either an aqueous sodium alginate solution or a calcium salt solution is applied to the inner packaging surface of a packaging film, and the other is applied or contained at least on the surface of an aggregate obtained by aggregating microgranular substances and arranged on the film, and the aggregate is packaged with the film, whereby the surface of the aggregate is covered with a gelled film.

[0008] When the granular aggregate is packaged with a packaging film, a calcium alginate film (gelled film) is formed between the aggregate and the film, so that the forming process and the coating formation process by film packaging are carried out simultaneously. Therefore, when fish eggs such as roe, pollock roe, and marinated pollock roe are used for granular foods, aggregate foods with respective flavors can be provided, and when artificial granular substances are used, unique granular aggregate foods can be provided.

[0009] Moreover, the method for manufacturing the granular material aggregate according to claim 2 of the present invention continuously applies either an aqueous sodium alginate solution or a calcium salt water container onto a long film that is being transported, and places the granular material aggregate coated or containing at least on the surface on the above-mentioned traveling long film, and wraps the placed granular material aggregate with the traveling long film to perform film packaging. It realizes the manufacturing method described in claim 1 as a continuous manufacturing by mechanization.

[0010] Moreover, the method for manufacturing the granular material aggregate according to claim 3 of the present invention is particularly applicable to the case where the granular aggregate is non-fluid like fish roe in the continuous manufacturing described in claim 2, and there is no particular problem. However, it is for the case where the fine granular material has no viscosity and the aggregate has fluidity. An appropriate binder is mixed to make the aggregate non-fluid and continuously supply it in a continuous rod shape onto the long film. After film packaging, the granular material aggregate is in a bound state and is appropriately cut. Since the granular material does not flow out from the film cut surface, it can be distributed as an aggregated food even after cutting.

[0011] Furthermore, the method for manufacturing the granular material aggregate according to claim 4 of the present invention is particularly in the continuous manufacturing described in claim 2, where the granular aggregate is intermittently supplied onto the long film, and the intermittent part is cut after film packaging. Even when the granular materials are not bound to each other, by covering the end of the aggregate with the film at the cut end, a food with a film formed on the end face part can be produced.

Advantages of the Invention

[0012] The method of the present invention is as described above. By bundling granular foods in a loose and separated state and film-packaging them as an aggregate, the forming process and the film-forming process can be performed simultaneously, and the simplification and mechanization of the production of granular material aggregate foods can be easily realized.

Embodiments for Carrying Out the Invention

[0014] Next, an embodiment of a manufacturing apparatus for realizing the method of the present invention will be described. The manufacturing apparatus can adopt the same configuration as a conventional continuous manufacturing apparatus for crab-flavored kamaboko, and is composed of a transfer unit 1, a film supply unit 2, a first solution application unit 3, a granular material supply unit 4, a packaging unit 5, and a cutting unit 6.

[0015] The transfer unit 1 transfers the packaging film 01 from the film supply unit (film roll) 2 to the cutting unit 5, and is formed by a plurality of conveyor belts.

[0016] The first solution application unit 3 sprays and applies the first solution 02 onto the surface of the traveling packaging film 01. In addition, instead of spray application, roller application or other appropriate application means may be adopted.

[0017] The granular material supply unit 4 continuously or intermittently supplies the aggregate 04 of the granular material 03 onto the traveling packaging film 01. The granular material 03 may be mixed with the second solution 05 to form the aggregate 04, or a biaxial supply mechanism may be adopted to simultaneously discharge the granular material 03 on the inner shaft side and the second solution 05 on the outer shaft side to form the aggregate 04. The illustrated example shows a biaxial supply mechanism.

[0018] The packaging unit 5 is composed of a guide member that raises both side edges of the packaging film 01 and winds them up above the aggregate 04, and a heat roller that welds the wound packaging film 01.

[0019] The cutting unit 6 cuts the transferred traveling object at predetermined intervals in a state where the aggregate 04 is wrapped with the packaging film 01.

[0020] Next, the production of granular aggregate food using the above device will be described. The packaging film 01 is transported and run by the transport unit 1 from the film supply unit (film roll) 2 to the cutting unit 6 (Fig. 3a), and the first solution 02 is applied to the upper surface of the transported packaging film 01 by the first solution application unit 3 (Fig. 3b).

[0021] The fine granular materials 03 are continuously supplied from the granular material supply unit 4 onto the packaging film 01 in a rod shape as an aggregate 04 (Fig. 3c). At this time, it is advisable to mix appropriate additives (flavoring agents, quality improvers, binders, etc.) corresponding to the product into the fine granular materials 03. Also, the second solution 05 may be premixed, or as in the illustrated example of the manufacturing apparatus described above, a twin-screw extruder may be employed to supply the aggregate 04 in a state where the second solution adheres to the outer periphery of the fine granular materials.

[0022] Then, in the packaging unit 5, both sides of the running packaging film 01 are wound up and welded to wrap the aggregate 04 with the packaging film 01 (Fig. 3d). Next, it is cut at predetermined intervals by the cutting unit 6, and the aggregate 04 covered with the packaging film 01 is produced as product A (Fig. 3e).

[0023] In particular, in the method of the present invention, an aqueous sodium alginate solution and an aqueous calcium salt solution are adopted for the combination of the first solution 02 and the second solution 05. When the aggregate 04 is packaged with the packaging film 01, sodium alginate and calcium ions react to form a calcium alginate film 06 on the surface of the aggregate 04.

[0024] Therefore, even when the packaging film 01 of product A is peeled off to obtain the food B in an edible state, the aggregate 04 is covered with the film 06, so the granular materials 03 do not separate from the aggregate 04 and become scattered.

[0025] Even when the granular materials 03 are aggregated as an aggregate 04 in a scattered state or when the granular materials 03 do not form a lump, it can be dealt with by appropriately mixing a suitable binder (such as minced fish) with the granular materials 03 in advance. In addition, when heat treatment is required for the edibility of the binder when the binder is used, it can be dealt with by providing a heating unit 7 at an appropriate location on the production line. For example, when adopting a binder from which the granular materials 03 are likely to flow out from the cut end at the time of cutting after packaging, when the binder is mixed with the granular materials 03 in advance, a heat treatment may be performed to ensure appropriate fluidity (to the extent that it does not flow out from the cut end at the time of cutting), or a heat treatment unit 7 may be provided between the packaging unit 5 and the cutting unit 6 (illustrated in Fig. 2) to prevent the packaged product (granular materials 03 mixed with the binder) from flowing out from the cut end at the time of cutting. Furthermore, when there is no risk of the granular materials flowing out at the time of cutting in the state where the binder is mixed, heat treatment may be performed after the cutting process. In particular, performing heat treatment in the final process is preferable in terms of contamination countermeasures.

[0026] Furthermore, when it is necessary to package the entire product A, the supply of the granular materials 03 and the second solution 05 onto the film (supply of the aggregate 04) may be performed intermittently, and as illustrated in Fig. 4, the cut end face may be covered with the packaging film 011 at the cutting portion.

[0027] The above embodiment shows an example of continuous production by a machine for the method of the present invention. As long as the method of the present invention is a technique for forming a calcium alginate film on the surface of the granular material aggregate simultaneously with film packaging, manufacturing means by other devices can also be adopted.
