Description

  The present invention relates to a seasoning food represented by bonito and its manufacturing technology.

  Skipjack tuna is produced as a traditional Japanese seasoning food, and is not only used as a shaving knot at home, but also as a raw material for seasonings such as powder seasonings and liquid seasonings. It is.

  Bonito is conventionally manufactured as follows. First, thaw the raw fish, cut out the edible portion by hand using a kitchen knife to produce the true meat section material, arrange the section material in a cello and heat it in boiled water at around 90 ° C for about 90-120 minutes To do. If the heating temperature is too high, the knot material will be broken, so it is necessary to keep the temperature constant during ripening. After ripening, let the knot material cool at room temperature, hold it with your hand so that it floats in water, and pull out the bones manually using buoyancy so that no force is applied to the knot material. After removing the water, the surface moisture is blown off with steam, and the cracked or chipped parts of the joint material surface are repaired with surimi to reduce the shape. After the reduced knot material is hardened by steaming, the roasting process dries the knot material with the heat obtained by burning the soot, and improves the storage and flavor of the smoked smoke. In the roasting process, the kneading material is left to stand after being heated and dried, and after performing an “ancho” process in which the moisture inside the knotting material is drawn to the surface and averaged, the operation of heat drying is repeated again. This heat-drying process varies depending on the size of the knot material, but is repeated about 15 times for the most commonly produced bonito knot.

  In such a conventional method for manufacturing bonito, each of the raw cutting process, the boning process, and the repairing process in which the raw material is disassembled and the edible portion is cut out is performed manually. It was difficult to promote mass production by machine because of the skill of the skilled worker. In the ripening process, there are differences in solids in the size and fat content of the bonito as a raw material, so temperature control during ripening was largely based on the experience of skilled workers. Furthermore, the drying process requires a treatment period of two weeks or more, and is a manufacturing method with low production efficiency as a whole. Patent Document 1 describes a method for producing fish bonito in which boiled bonito is ripened with superheated steam, and the ripening is performed by injecting steam into a heating apparatus containing the chopped material. Is done.

  As a seasoning food such as skipjack, instead of using true meat as a knot material, seasoning is made using a paste-like knot material by refining the knot material, including parts that were not used in the past. Attempts have been made to produce food products. For example, Patent Document 2 describes a method for producing bonito kneaded knots using a paste made by refining them including a portion not conventionally used in addition to the bonito true meat, and the knot material is steamed. It is made to heat by. Patent Document 3 describes a method for manufacturing bonito kneaded knots using a piece of meat obtained as a by-product during the manufacture of bonito rough bonito or bonito, and the knot material is heated by microwaves. Yes. Furthermore, Patent Document 4 describes a method for producing a nodular processed food using surimi or strip-shaped raw meat as a node material, and the node material is heated by Joule heat in a container provided with electrodes. I am doing so. Patent Document 5 describes a method for producing kneaded knots using kneaded knots, koji and sardine kneaded and kneaded knots as a knot material. Qi treatment is done.

  In the above-mentioned conventional method for producing food for saving food, boiled, microwave, electric heating, superheated steam is used as the method for heating the material for saving, but the heating uniformity required for the production of bonito, heated fish meat It was difficult to satisfy all of quality, tackiness, and heat treatment efficiency. In particular, in the heating by boiling, there is a problem that the umami component is eluted in the boiling water. In addition, the conventional method of heating material by electrical heating is to use an insulating container and fill the container with the material, and the heated material sticks to the container for mass production. Was unsuitable. The heating method using superheated steam is batch-type heating in a closed heating apparatus, so that the heating efficiency is poor and unsuitable for mass production.

  In the conventional methods for producing food savings, the drying process takes a long time, which is a major cause of reducing the production efficiency. In order to efficiently produce mass-saving foods in large quantities, it is considered essential that the surface area of the knot material is as large and thin as possible. However, in the above-described conventional manufacturing method, even if the fish meat is thinly formed, the material for the knot is destroyed in the heating process, and furthermore, since it is a batch-type heating, the mass production of the food is continuously produced. It was technically difficult to do.

  An object of the present invention is to make it possible to efficiently produce a seasoning food represented by bonito and its seasoning food in a short time.

  The seasoning food of the present invention is a seasoning food produced by heating and drying a seasoning material such as skipjack, and the paste-like seasoning material is 5 mm or less in thickness at the carry-in end of a heating unit having a conveyor belt. While supplying the strip of thickness, the seasoning material is heated by supplying an electric current to the seasoning material, and the seasoning material that has been heated and processed into a strip is dried and formed into a strip.

  The method for producing a seasoning food of the present invention is a method for producing a seasoning food by heating and drying a seasoning material such as bonito, and is a paste-like seasoning material at the carry-in end of the conveyor belt. Is supplied in the form of a strip having a thickness of 5 mm or less, and a heating unit having the conveying belt that conveys the seasoning material, while feeding the seasoning material while passing the seasoning material, the seasoning It has an electric heating process for heating the material and a drying process for drying the seasoning material after the heat treatment.

  Since the seasoning material is made into a paste, the thickness of the seasoning material is supplied to the conveyor belt in a thin thickness of 5 mm or less in a strip shape, and the electric heating is performed, the seasoning material can be heated uniformly and heated. The time required for the drying process can be greatly shortened, and the production efficiency of the seasoning food can be improved. By electrically heating the seasoning material, it is possible to release only the moisture and suppress the outflow of the umami component and the nutrient component, and it is possible to produce a high-quality seasoning food. Since it is not necessary to boil the seasoning material, the installation area of the manufacturing apparatus can be reduced.

(A) is the schematic which shows an example of the manufacturing method of a seasoning foodstuff, (B) is the schematic which shows the modification of the manufacturing method of a seasoning foodstuff. It is an expanded sectional view which shows the heating unit shown by FIG. FIG. 3 is a plan view showing a part of FIG. 2. It is sectional drawing which expands and shows a part of FIG.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 (A) is a schematic view showing an example of a method for producing a seasoning food of the present invention. The seasoning food is mainly made from fish meat such as skipjack, and the edible portion of the raw material is refined by a grabber, chopper and crusher, and a minced or paste-like seasoning material is produced in advance. At this time, it is desirable to keep the seasoning material at a temperature of about 5 ° C. and perform a deaeration process to make a paste in a low oxygen atmosphere.

  The paste-like seasoning material is band-shaped and heated by the heating unit 10 shown in FIG. 1A, and the seasoning material after the heat treatment is dried by the drying unit 20. The dried strip-like seasoning material is smoked by the roasting unit 30 and is commercialized as a seasoning food. The smoke-treated band-like seasoning food is cut into a predetermined length and packaged. In order to pass the seasoning material heat-processed by the heating unit 10 to the drying unit 20 and the roasting unit 30 while passing the units, the transport conveyor 40 penetrates the drying unit 20 and the roasting unit 30. Is provided. The conveyor 40 has a conveyor belt 43 that is stretched between a carry-in roller 41 and a carry-out roller 42, and supports the conveyor belt 43 in the drying unit 20 and the roasting unit 30. For this purpose, a plurality of guide rollers 44 are arranged.

  Some seasoning foods are commercialized in a dried state without being smoked. In that case, as shown in FIG. 1B, after the drying process by the drying unit 20 is performed, the package is cut into a strip having a predetermined length. Also in the case shown in FIG. 1B, the seasoning material is automatically conveyed to the drying unit 20 by the conveyance conveyor 40.

  2 is an enlarged longitudinal sectional view showing the heating unit shown in FIG. 1, and FIG. 3 is a plan view showing a part of FIG. As shown in FIG. 2, the heating unit 10 is provided with a molding unit 11, and the seasoning material refined in a paste form is transferred to the molding unit 11 by a pump or the like.

  The molding unit 11 has a housing part 12 that houses the paste-like seasoning material W and a molding part 13 for molding the material, and a discharge pump 14 is provided between the housing part 12 and the molding part 13. It has been. The molding part 13 is provided with a discharge port 15 for discharging the seasoning material W. The vertical height of the opening of the discharge port 15 is several mm, and the seasoning material W is fed from the discharge port 15. As shown in FIG. 2 and FIG. 3, it is formed into a strip shape and discharged to the heating unit 10.

  The heating unit 10 has a roller electrode group 22 composed of a plurality of roller electrodes 21 arranged in parallel and parallel to each other, and each roller electrode 21 is rotatably supported by a support base 23 and is driven not shown. The device is driven to rotate in the direction indicated by the arrow. The roller electrode group 22 is provided with a water-permeable conveyance belt 24 made of cloth or nonwoven fabric. The water-permeable conveyance belt 24 has water retention and has conductivity due to water supplied from a water supply device (not shown). A guide roller 25 is disposed on the upstream end side of the heating unit 10, and guide rollers 26 and 27 are disposed below the roller electrode group 22 so as to correspond to both ends of the roller electrode group 22. Each of the guide rollers 25 to 27 is parallel to the roller electrode 21, and by rotating the roller electrode 21, the conveying belt 24 moves from the loading end at the left end in FIG. 2 to the unloading end at the right end. It is transported and driven as indicated by an arrow. The roller electrode group 22 shown in FIGS. 2 and 3 has eight roller electrodes 21, but the number of roller electrodes 21 is arbitrarily set.

  Each roller electrode 21 is connected to a power supply unit 28 by a cable, and a high-frequency current having a reverse polarity is supplied to the roller electrodes 21 adjacent to each other. As a result, a current flows between the two roller electrodes 21 adjacent to each other in the seasoning material W discharged in a band shape from the discharge port 15 of the molding unit 11 onto the transport belt 24. In this energization heating process, the seasoning material W generates heat due to Joule heat and is heated to a temperature of 80 to 90 ° C.

  4 is an enlarged cross-sectional view of a part of FIG. The top surface of the seasoning material W is open, and the seasoning material W is energized and heated by the roller electrode 21 from the bottom surface side. A larger amount of current flows from both roller electrodes 21 to the strip-shaped seasoning material W than to the upper side of the seasoning material W. For this reason, when the thickness of the seasoning material W is increased, the energization amount of the upper portion of the seasoning material W is smaller than that of the lower portion. Therefore, when the thickness of the seasoning material W is increased, the heating temperature of the upper portion becomes lower than that of the lower portion. However, when the thickness dimension of the seasoning material W is set to a certain value or less, the seasoning material W Can be heated at the desired uniform temperature.

  As shown in FIG. 4, the thickness dimension of the seasoning raw material W was set to D, and various experiments were performed by varying the thickness dimension. The thickness dimension D of the seasoning material W corresponds to the vertical dimension of the opening of the discharge port 15, and the width dimension A corresponds to the horizontal dimension of the opening.

  In the manufacturing apparatus shown in FIG. 1 (A), the seasoning material W that has been heat-treated by the heating unit 11 is dried by the drying unit 20 and then smoked by the roasting unit 30 to be commercialized. Is done. On the other hand, in the manufacturing apparatus shown in FIG. As described above, when the seasoning material W is continuously dried while being transported by the transport conveyor 40, or in addition to the drying process, the seasoning material W can be efficiently manufactured. it can. However, each process may be performed by the drying unit 20 and the roasting unit 30 that are arranged separately from the heating unit 10 without continuously performing the drying process and the roasting process, that is, the smoke treatment. .

  When the electric heating treatment and the drying treatment are performed, the seasoning material that has been in the form of a strip having a thickness of 5 mm or less before heating shrinks to a thickness of about 30% before the heat treatment, and the moisture content is 20% or less. It becomes the seasoning food. When performing the heat treatment, the seasoning material W is continuously supplied from the molding unit 11 to the heating unit 10. Before performing the drying process, the seasoning material W in a striped state is cut into predetermined lengths, and the cut seasoning material W is dried or roasted in addition to the drying process. Or may be cut to a predetermined length after the drying process or roasting process is completed. In any of the manufacturing methods, the seasoning food is a strip with a thickness of about several millimeters, and is manufactured using a paste-like seasoning material. A person can easily grind the seasoning food and use it for cooking soup stock.

  In FIG. 1, the transport distance between the drying unit 20 and the roasting unit 30 is shown short for convenience of drawing, but in actuality, the transporting speed in the heating unit 10 and the time of the drying process or the roasting process are corresponded. Each of the transport distances is longer than in the illustrated case.

  After thawing the frozen bonito, it was dropped into three pieces, and after removing the head, bones and internal organs, the meat was taken with a grabber. Next, a paste-like seasoning material W was obtained with a high-speed cutter while cooling it to 5 ° C. or lower. The obtained seasoning material W is transferred to the forming unit 11, then formed into a strip shape having a width of 7.5 cm, a length of 15 cm, and a thickness of 2 mm, and discharged onto the conveying belt 24 of the heating unit 10. While being transported and moved, it was heated by energization under conditions of 150 V and 0.5 to 10 A continuously. The heated seasoning material W was allowed to cool and then dried at 80 ° C. with an electric hot air dryer.

  On the other hand, as a comparative example, the seasoning material molded into the same size is heated in 95 ° C. warm water for 1 minute (boiling treatment), and thereafter dried in the same manner as in the case of energization heating to make a sheet-like seasoning Trial foods were made.

  When the ripening treatment was performed as in the comparative example, most of the molded seasoning materials were torn in the boiling water during the heating, but when the heating processing was performed using the heating unit 10, the seasoning material W was There was little torn. The general components of the fish paste after heating are 71.9% moisture, 27.8% crude protein, 0.3% fat, 1.4% ash when heated by heating, and when boiled as in the comparative example, The moisture content was 70.8%, crude protein was 29.0%, fat content was 0.2%, and ash content was 1.1%. Moreover, the time required for drying until the water content was 20% or less was 2 hours in both cases where the current was heated and boiled. At the end of drying, the broth was extracted at a weight of 2% based on the method of Japanese Agricultural Standards for shaving sections, and the extract content was measured. As a result, the extract content (%) is 23.7% when heated by current, compared to 17.9% when the ripening treatment is performed, and it is possible to continuously produce a high seasoning food according to the present invention. did it.

  A low protein material such as shavings, haramo, head and tail discharged from a frozen bonito processing plant is pulverized by a mass collider into a seasoning material W, and the same as in Example 1 using the heating unit 10 of the present invention. Condiment foods were prototyped under the following conditions. As a result, it was possible to continuously produce a seasoning food having a high binding property even when these low protein materials were used. The extract (%) was shaving powder 19.1%, Haramo 12.2%, head + tail 14.0%.

  The seasoning foods prototyped in Examples 1 and 2 were further subjected to roasting treatment by burning firewood for about 3 hours to half a day. When this seasoning food was pulverized and dashi stock was extracted in the same manner as normal bonito bonito, it was extracted from commercially available bonito bonito and had a flavor and good taste.

  In the embodiment described above, the molding unit 11 having a vertical width of the discharge port 15 of 2 mm is used, and not only the bonito meat but also the cutting powder, haramo, Seasoning foods were manufactured using low protein materials such as tails. As a result, compared with the case where the seasoning material is boiled, that is, heated in warm water, the energizing heating process releases only the moisture and suppresses the outflow of the umami and nutrient components, and the binding power Was able to produce a strong seasoning material. As a result of the trial production, when the thickness dimension is 5 mm or more, the upper part of the seasoning material W is not heated to a predetermined temperature, and the binding force does not become strong, but if it is in the range of 5 mm or less, particularly 2 to 1 mm. In addition, the seasoning material W as a whole could be heat-treated by improving the uniformity of the heating temperature and heating the seasoning material having a large binding power.

  The heat-treated seasoning material W is transported to the drying unit 20 and dried. In the drying process, the moisture remaining in the seasoning material W is removed by conveying the seasoning material W after the heat treatment to the drying unit 20. At the time of this drying process, as in Example 3, the seasoning material W is dried with warm air generated by burning heat from soot, electricity, or gas, and smoke-treated with smoke to perform a dry-drying process. You may make it perform a drying process. As the drying treatment after the heat treatment, sun drying is also possible, but drying and soot in a short time can be performed by drying treatment in the drying unit 20 or by performing a drying treatment by the drying unit 30. It is possible to perform the pasting. Since the binding power of the seasoning material is enhanced by the heat treatment, the workability of the drying treatment and the roasting treatment can be improved.

  As described above, when the seasoning material W formed in a strip shape is supplied onto the water-permeable conveying belt 24 disposed on the roller electrode 21, the thickness dimension D of the seasoning material W is set to 5 mm or less. Even when the upper surface of the seasoning material W is exposed to the outside air, the seasoning material W can be heated to a uniform temperature as a whole. Thereby, conventionally, the boiled water required for heating became unnecessary, elution of the extract component into the boiled water was suppressed, and a seasoning food containing a large amount of the extract was obtained. In addition, the amount of drainage could be greatly reduced because boiled water that was conventionally required for heating is no longer necessary. Furthermore, the heating container which was required in the system by conventional energization heating becomes unnecessary. For this reason, the installation area of the heating unit 10 can be reduced, and the seasoning food production apparatus can be made compact.

  When the energization heat treatment is performed while being conveyed by the conveyance belt 24, the heat-treated strip-like or sheet-like seasoning material W has a high binding force and is less likely to collapse, and the seasoning material in the process after the heat treatment. Handling of W becomes easy. Furthermore, there is an advantage that a material containing a large amount of flesh other than the true meat, a material having a lot of fat, and a material having a relatively high moisture content and a high fluidity can hardly be collapsed during the heat treatment.

  In order to perform the drying process or the like after the heat treatment seasoning material continuously formed into a band or sheet, it is cut into a band having a predetermined length in consideration of handling in a subsequent processing step. Although it is possible to cut before heating, it is desirable to cut after heating.

  As described above, the drying and sooting may be performed by the roasting process, and the drying process and the roasting process are separated, and the drying process is performed by the drying unit 20 as shown in FIG. After performing the above process, the roasting process may be performed by the roasting unit 30. In this case, the time for the roasting process can be shortened. At the time of drying or roasting, the seasoning material W is thinly formed into a strip or sheet, so that these times can be greatly reduced compared to conventional drying, and roasting Can significantly reduce the amount of soot required for the process.

  As seasoning material W, not only bonito, but also fish such as tuna, mackerel and sardines, seafood such as shellfish, squid and octopus, livestock such as pigs and cows, seaweed and vegetables are crushed. You may make it manufacture a seasoning raw material individually or by mixing these. Moreover, after these seasoning materials W are heat-processed, you may make it sprinkle a seasoning liquid, a powdery seasoning, and another auxiliary material. In the production method of the present invention, since the seasoning material is processed and heated in a paced manner, as described above, a mixed-type seasoning food containing seafood, seaweed, etc. is efficiently produced. Can do.

  The bonito, a traditional seasoning food, is a lump that corresponds to the size of the fish fillet and needs to be cooked in a shaved state, whereas the seasoning food of the present invention uses a paste-like material. Since it is heated and dried to produce a strip, it can be easily crushed. As a result, the seasoning food can be poured into the broth while being finely crushed by hand at the time of cooking. Therefore, the shaving operation of the seasoning food becomes unnecessary, and the cooking work can be easily performed. Even when the seasoning food of the present invention is pulverized into a powder and commercialized, the pulverizing operation can be easily performed. Thus, the seasoning food of this invention can be commercialized not only when it is commercialized as a strip, but also as a powder.

  The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
