[0011] [Figure 1] It is a flow diagram showing the basic configuration of the method for producing a dried product containing squid viscera of the present invention. [Figure 2] It is a flow diagram showing another configuration of the method for producing a dried product containing squid viscera of the present invention. [Figure 3] It is a production flow diagram in an example of the present invention. [MODE FOR CARRYING OUT THE INVENTION]

[0012] Hereinafter, the present invention will be described in detail with reference to the drawings. Figure 1 is a flow diagram showing the basic configuration of the method for producing a dried product containing squid viscera of the present invention. As shown in the figure, the present method for producing a dried product containing squid viscera mainly comprises: a mixing step P10 of obtaining a liquid mixture 3 by stirring squid viscera 1 and a vegetable raw material 2; a drying step P20 of obtaining a dried mixture 4 by drying the liquid mixture 3; and a morphogenesis step P30 of processing the dried mixture 4 into a powdery or granular form. Note that a protein-containing vegetable raw material can be suitably used as the vegetable raw material 2.

[0013] According to the method for producing a dried product containing squid viscera of the present invention having such a configuration, first, in the mixing step P10, squid viscera 1 and vegetable raw material 2 are stirred to obtain the liquid mixture 3; next, in the drying step P20, the liquid mixture 3 is dried to obtain the dried mixture 4; and then in the morphogenesis step P30, the dried mixture 4 is processed into a powdery or granular form, thereby obtaining the dried product 10 containing squid viscera.

[0014] In the method for producing a dried product containing squid viscera according to the present invention, cadmium-removed squid liver can be suitably used as the squid viscera 1. One of the main uses of the dried product containing squid viscera 10 according to the present invention is as a component of feed for fish and the like, and squid liver has a high feeding attraction effect on fish and the like, and is suitable as a feed component. There are no particular limitations on the type of squid that can be used, including Japanese flying squid, Pacific squid, Argentine shortfin squid, purpleback flying squid, European common cuttlefish, spear squid, whitespotted conger, inkfish, Japanese common squid, etc. Furthermore, any state of fresh, refrigerated, or frozen product may be used.

[0015] As the squid viscera (liver) 1, for example, a squid viscera solution prepared by the following procedure can be suitably used. That is, the squid viscera are liquefied (dissolved), unnecessary impurities such as beaks and eyeballs are removed by filtration or the like, cadmium removal treatment is performed using citric acid and a chelating resin, to obtain a squid viscera solution having a cadmium concentration of 2.5 ppm or less. A predetermined amount of salt is added thereto as necessary.

[0016] In the method for producing a dried product containing squid viscera according to the present invention, as described above, a protein-containing vegetable raw material can be suitably used as the vegetable raw material 2. As the protein-containing vegetable raw material, plants for providing vegetable protein can be used without particular limitation, and vegetables can be particularly suitably used. For example, it is a plant of the genus *Dioscorea* including Chinese yam, but is not limited thereto, and a wide range of protein-containing vegetables can be used, including other root vegetables, subterranean stem vegetables, stem vegetables, fruit vegetables, leafy vegetables, and the like.

[0017] In particular, waste materials such as processing residues of agricultural, forestry, and fishery products can be suitably used as plant-based raw materials 2. The squid innards 1 according to the present invention are mostly discarded during squid processing, and this contributes to the effective utilization of underutilized parts, resource reuse, and cost reduction of products. As plant-based raw materials 2, for example, waste materials from post-harvest preparation such as non-edible parts removed during preparation before shipment after harvesting of yams, or waste materials generated during the processing of agricultural, forestry, and fishery products can be effectively utilized, which also contributes to the effective utilization of underutilized parts, resource reuse, and cost reduction of products.

[0018] In the mixing process P10 of the present invention's method for producing dried squid innards, the mixing ratio of squid innards 1 and plant-based raw materials 2, such as protein-containing plant-based raw materials, in the resulting liquid mixture 3 can be such that squid innards 1 make up 49% by weight or less. In other words, in the mixing process P10, the amount of plant-based raw materials 2 can be greater than the amount of squid innards 1 by weight. This allows for the production of a liquid mixture 3 with a better mixing state, and ultimately, a good dried mixture 10 can be obtained.

[0019] The mixing ratio, or blending ratio, of each raw material to obtain the liquid mixture 3 can be designed to match the final dry mixture 10 to be obtained. For example, the amount of squid innards 1 can be set to 49% by weight, 40% by weight, or 30%, 10%, 5%, etc., and can be freely determined as appropriate. Furthermore, even mixing ratios (blending ratios) exceeding 49% by weight, such as 50% or 60% by weight, are not excluded from the present invention and are within the scope of the present invention.

[0020] For example, the plant-based raw material 2, which is a pulverized product of vegetables such as yams, and the squid internal organs 1 (liver) may be mixed in a ratio of 10:3 or 3:10. In this case, the weight percentage of squid internal organs 1 in the liquid mixture 3 will be 23% by weight in the former mixing ratio and 77% by weight in the latter mixing ratio.

[0021] Furthermore, for example, the dried squid innards-containing product 10 according to the present invention can be used as feed or a raw material for aquaculture of fish, shrimp, etc., but there may be an appropriate range for the mixing ratio of squid innards 1 and plant raw material 2 depending on the target fish species and the size of the fish. Depending on the case, the mixing ratio of squid innards 1 and plant raw material 2 in the prepared liquid mixture 3 can be designed.

[0022] A drum dryer can be suitably used for the drying process P20 in the drying method for producing dried squid innards according to the present invention. The liquid mixture 3 subjected to the drying process P20 is in liquid form and is a material suitable for drying using a drum dryer. This allows the squid innards 1 to be dried well in the form of a mixture with the plant-based raw material 2.

[0023] In a drum dryer, the liquid to be treated is thinly applied to the surface of a drum heated by steam or the like, and the liquid is heated and dried while the drum rotates. The dried material formed by the drying process is formed as a thin film on the drum surface. In drying process P20 of the present invention's method for producing dried squid innards using a drum dryer, the liquid mixture 3 applied to the drum surface is dried, and a dried mixture 4 formed as a thin film on the drum surface is obtained.

[0024] The dried material obtained on the drum surface of the drum dryer is recovered by scraping it off with a scraper knife or the like. In the morphogenesis process P30 of the squid innards-containing dried product manufacturing method of the present invention, the dried mixture 4 formed as a thin film on the drum surface is recovered by scraping it off with a scraper knife or the like, and this is subjected to grinding treatment using an oat mill or the like to obtain squid innards-containing dried product 10 in the form of a powder or granules.

[0025] Depending on the specifications of the drum dryer, it may be possible to automatically scrape off the dried material, or to automatically scrape it off in powder or granular form. In this case, the morphogenesis process P30 will also be carried out by the drum dryer.

[0026] As mentioned above, while technologies for powdering squid liver have existed for some time, their practicality was limited due to the large scale of the equipment required. However, according to the present invention, powdering and granulation can be easily achieved. In particular, when a drum dryer is used in the drying process P20, the effects can be obtained to a high degree. As a result, it is now possible to provide dried squid liver that can be stored for a long time and used whenever needed.

[0027] Figure 2 is a flowchart showing another configuration of the squid innards-containing dried product manufacturing method of the present invention. As shown in the figure, in addition to the configuration described in Figure 1, the squid innards-containing dried product manufacturing method is characterized by the fact that vitamins and other auxiliary materials 25 are mixed in during the mixing process P210.

[0028] According to the method for producing dried squid innards with the above configuration, first, in the mixing process P210, squid innards 21 and plant-based raw materials 22 are mixed with vitamins and other auxiliary materials 25 to obtain a liquid mixture 23. Then, in the drying process P220, the liquid mixture 23 is dried to obtain a dried mixture 24. Finally, in the morphogenesis process P230, the dried mixture 24 is transformed into a powder or granular form to obtain dried squid innards 210. For example, by using this dried mixture 210 as feed for fish, etc., it is possible to create feed fortified with various vitamins necessary for fish, shrimp, etc.

[0029] Furthermore, the squid innards-containing dried product consists of squid innards and plant-based raw materials, and is in powder or granular form, with the following uses: 、 Dried squid innards containing any of the listed ingredients themselves are also within the scope of the present invention. Aquaculture feed and additives for aquaculture feed Livestock feed, seasonings, and food ingredients for human consumption (excluding seasonings)

[0030] When using the squid innards-containing dried product of the present invention as feed for aquaculture or as an additive for feed for aquaculture, the target fish species are not limited and it can be applied to a wide range of species. It may be used as a powder to be added to feed, or it may be used as feed in powder form, or the squid innards-containing dried product may be made into granules or pellets and used as feed as is. As mentioned above, the mixing ratio of squid innards and plant-based raw materials can be changed as appropriate.

[0031] The dried squid innards product of the present invention can also be used as food for humans and animals such as livestock. For example, the dried squid innards product of the present invention can be used as a seasoning to cook squid ink spaghetti. [Examples]

[0032] As an example of the present invention, the manufacturing flow of "Ika Goro Powder," a powdered dried product containing squid innards, will be described, but the present invention is not limited thereto. Figure 3 is a manufacturing flow chart for an embodiment of the present invention. As shown in the figure, the powdered dried squid innards product "Ika-goro Powder" can be manufactured as follows. That is, vegetables such as yams are washed and crushed to make plant-based raw materials, and these are mixed with squid liver (Ika-goro) in a stirrer (mixing process). When using yams, for example, a liquid mixture can be obtained by mixing them in a ratio of 10 parts by weight of yams to 3 parts by weight of Ika-goro.

[0033] The obtained liquid mixture is transported to a drum dryer using a screw conveyor and dried (drying process). The resulting dried mixture is taken into a container and processed in an o-mill if it is to be made into a powder, or in a granulator if it is to be made into granules (morphogenesis process) to obtain the respective products.
