Description

  The present invention relates to a method for producing canned foods that makes use of the original flavor of fish. More specifically, the present invention relates to a method for producing canned fish meat that has undergone a drying process such as dried fish and a roasting process, instead of raw fish as it is.

Canned food has long been known as a method for long-term preservation of food, and various canned foods have been marketed so far. Generally, canned foods are prepared by filling the contents in a suitable empty can and sealing them, and sterilizing them at high temperatures to provide cooking and storage stability. Even if unsuitable or canned, the texture and flavor may be impaired.
Many fish canned foods are made by adding a thick seasoning, but this is because simply adding raw fish meat to make canned foods often damages the texture and flavor. In particular, for fish with a light taste, it is often the case that dark seasonings are used because the texture and flavor are significantly impaired (for example, Patent Document 1 etc.). There was no canned food.

Patent Document 2 describes “a grilled fish in a container obtained by sealing and packaging a grilled fish obtained by firing a dried fish product in a container such as a retort pouch, and then performing a heat sterilization process”.
Patent Document 3 describes “a fish packaging method in which a bag and a edible natural water-absorbing substance are sealed in a bag and then the bag is sealed in a vacuum state”.
Patent Document 4 states that “a step of immersing the remaining meaty fish bones in which the fish has been dropped into three pieces in the seasoning liquid, a step of drying the meaty fish bones that have been drained in cold air; And a process for producing a fish-bone with packaged meat, comprising a step of vacuum-packaging a heat-resistant film wrapping material together with kelp and then sterilizing under pressure and heat.
Patent Document 5 describes “a fish package having a seaweed sheet in which a seaweed sheet is placed at least on the side of a fish in a bag and heated and integrated”.

  It is an object of the present invention to provide a canned fish that takes advantage of the original taste of fish, is not deeply flavored, and has no fishy odor.

In view of such a situation, the inventors have intensively studied to make canned fish that can take advantage of its flavor, using a raw fish that has been subjected to a drying treatment, and then roasting it. It was found that canned fish without liquefaction and sterilization under optimal conditions can be used to fish with a good texture and flavor without using a thick seasoning even for fish with a light taste. It was also found that filling kelp together not only reduces the drip, but also reduces the moisture of the fish meat, resulting in a canned product that feels dry like dried fish.
The present invention roasts fish that has been subjected to a drying treatment so that the water content after the drying treatment is 40 to 80%, and is sterilized at 110 to 130 ° C. for 60 to 120 minutes as a can without injection. The gist is a method for producing canned fish. Furthermore, the gist of the present invention is also a method for producing canned fish by filling 1 to 3 g of dried kelp together with 50 to 100 g of roasted fish.

  According to the production method of the present invention, even if it is a canned fish, it is not necessary to use a seasoning with a strong seasoning, and a canned fish having a texture and flavor utilizing the original taste of the fish can be produced. In addition, canned foods with a drip-like texture like dried fish can be produced.

Hereinafter, embodiments of the present invention will be described in detail.
The present invention roasts fish that has been subjected to a drying treatment so that the water content after the drying treatment is 40 to 80%, and is sterilized at 110 to 130 ° C. for 60 to 120 minutes as a can without injection. The present invention relates to a method for producing canned fish. The fish used as the raw material of the present invention is not particularly limited, but is applicable to those with a light taste. White fish is preferred, and particularly preferred are red fish, horse mackerel, barracuda, flounder, sawara, azalea, matoudai, red sea bream, melon, and hockey.
These raw fish are dried. As a drying method, a drying method such as sunlight, cold air, hot air, infrared rays or the like is used. At this time, the raw fish may be immersed in a seasoning solution or salt water using salt, mirin, soy sauce, sake, sugar or the like before the drying treatment. In addition, the raw fish may be frozen after being dried. The drying process is performed so that the water content after the process is 40 to 80%. The dried raw material fish is appropriately shaped as needed and then roasted. The roasting is performed by direct fire, infrared rays, or the like, and is appropriately adjusted so that the yield after roasting is 80% or more. Perform to the extent that the protein on the surface of the fish is denatured and hardened, or to a degree that makes the grilled eyes slightly sticky.
After roasting, allowing to cool, it is packed in a can of appropriate size and wound and sterilized by a sterilizer. At this time, in general canning, water or seasoning liquid is injected, but in the present invention, no liquid injection is performed. The can used is a molded metal container, and may be made of, for example, iron or aluminum, and the inner surface of the can may be coated. At this time, the sterilization is performed at 110 to 130 ° C. for 60 to 120 minutes. In this manner, the production method of the present invention and canned fish obtained thereby can be obtained.

Moreover, even if it passes through a drying process and a roasting process as mentioned above, a certain amount of drip will arise in a sterilization process. When a moist texture is required, it may be left as it is, but in the case of a product that emphasizes the dryness, the dryness of the fish surface is impaired by the presence of the drip. In that case, it is preferable to fill together the dried kelp, which is the second aspect of the present invention. 1 to 3 g of dried kelp is used for 50 to 100 g of roasted fish. When 3 g is used, the drip is almost completely absorbed and has the effect of reducing the water content of the fish meat. Moreover, 1 g does not absorb the drip completely, but the amount of drip is reduced, and the viscosity of the drip is increased by the components of the kelp, and the drip wateriness is reduced.
Although it is possible to use water-absorbing materials other than kelp, kelp is suitable because it does not affect the taste and flavor of fish, has a large amount of water absorption, and is a thin sheet with moderate thickness. . In kelp, the water absorption efficiency of slightly softer kelp like Nagacomb is good, but slightly harder kelp such as Macombu and Mitsushi Kombu can be used in the same way. Depending on the part and grade of the comb used, for example, in the case of Nagacomb, 3-4 pieces of sections with a size of about 3 × 3 cm corresponded to 1-1.5 g. In the manufacturing process of canned food, it is preferable in terms of appearance that the dried kelp pieces are placed in the bottom of the can and the fish is filled on top of the dried kelp pieces. Is preferable in terms of drip retention.

  The present invention will be described in more detail with reference to the following examples, which are merely illustrative and the present invention is not limited thereto.

Example 1: Manufacture of canned fish according to the present invention The head and tail of a horse mackerel (water content 75%) which has been soaked in salt water and then dried in cold air are cut into half bodies, and this is made into a continuous roasting furnace (direct fire + distant Infrared, temperature 300-600 ° C.). The yield of fish after roasting was 88%. 100 g of this half body was put into a square No. 5 can A (inner diameter 103.4 × 59.5 mm, height 30.0 mm), and was sterilized after being wound with a winder. Sterilization was performed at 117 ° C. for 70 minutes.

Example 2: Sensory evaluation of the product of the present invention The product of the present invention (Aji) obtained in Example 1 was produced in the same manner except for the dry treatment of Example 1 using raw horse mackerel as a raw material (Comparative Example) The sensory evaluation was performed. Evaluation was performed on the texture, taste, odor, and overall evaluation by 5 panelists of each gender. The results are shown in Table 1. In the table, ◎ indicates very good, ○ indicates good, and △ indicates not very good.
It was confirmed that the product manufactured by the manufacturing method of the present invention has a good texture and flavor.

Test Example 1: Water absorption of various kelp Water absorption of various kelp was tested. In the same can used in Example 1, 1-3 g of kelp and 10 g of water were added, and heat sterilized under the same conditions as in Example 1. As shown in Table 2, it was considered that Nagacomb with a small thickness had a large surface area even with the same weight, a relatively large amount of water absorption, and good efficiency. However, a certain water absorption effect was recognized in all types of kelp.

Example 3: Manufacture of canned fish with canopy according to the present invention The head and tail of a horse mackerel (water content: 70%) and hockey (water content: 63%) which had been soaked in salt water and dried in cold air were cut into half bodies. Was roasted in a continuous roasting furnace (direct fire + far infrared ray, temperature 300 to 600 ° C.). The yield of fish after roasting was 88%. About 65g of roasted fish and 1g or 3g of Nemuro Nagacomb are put into a square No. 5 can A (inner diameter 103.4 x 59.5mm, height 30.0mm) Went. Sterilization was performed at 115 ° C. for 75 minutes.
The amount (g) of drip generated in each can was measured for each 10 cans, and Table 3 shows the average value, maximum value, and minimum value. When 3 g of kelp was added, the drip was almost completely absorbed. About 1 g of the drip amount remained at 1 g, but the viscosity of the drip was increased by the components of kelp, and the presence of the drip was not noticeable. By adding kelp, the canned fish of the present invention had a dry feeling and became more like a can of dried fish. The taste of kelp did not affect the taste or flavor of fish. Further, the canned product was subjected to a storage test at 35 ° C., and even after 97 days, no change was observed in the drip amount or the like regardless of the presence or absence of kelp. This result can be regarded as a stability test of about one year at room temperature.
Changes in the water content and salinity of fish meat due to the addition of kelp were confirmed. As shown in Table 4, the water content of fish meat was 62.5% when dried dried mackerel with a moisture content of 70.6% was only 62.5%, but it was 53 when 3 g of kelp was canned together. It was found that not only the amount of drip but also the water content of fish meat was reduced. Further, as shown in Table 5, the salinity concentration increased as the water content of the fish meat decreased.

By the production method of the present invention, it is possible to provide a canned fish having a texture and flavor utilizing the original flavor of fish.
