Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a processed algae food, and particularly to a method for producing a processed algae food suitable for processing raw algae of seaweed.

[0002]

BACKGROUND OF THE INVENTION Algae laver, a marine product, contains abundant proteins and carbohydrates as well as many vitamins and calcium,
It has been eaten since ancient times in Japan as a food containing inorganic substances such as iron and phosphorus and having a high nutritional value in terms of nutrition. In particular, the product made from seaweed, which grows naturally in the rocky areas on the coast, as a baking raw material has a good taste and is favored as rock paste.

These seaweeds are generally produced through the following steps. That is, the seaweed picked and collected is dehydrated to a water content of 8% to 9% using a fully automatic dryer, and then primary dried to be processed into a thin plate-shaped dry seaweed.
It is stored frozen at 20 ° C to -25 ° C (sometimes stored at room temperature instead of frozen).

Next, the dried and dried seaweed is put in a roasting furnace and heated at a temperature of 60 ° C. to 80 ° C. for about two and a half hours to prevent spoilage, and the water content is reduced to 2% to 3%. After that, it is heated with a roasted laver machine to obtain a roasted laver with a water content of 2% or less, which may be further seasoned.

[0005] To process and season such seaweed,
The manufacturer's original method is adopted to improve the appearance, taste, and texture of the product. In addition to the Tsukudani, for example, the seaweed used as a sprinkle or as a topping for food (sprinkle, surface finish) is often a plate-shaped processed seaweed that is finely cut.

[0006]

However, the seaweed is subjected to a predetermined processing depending on the state of the algae, and has a suitable size, for example, as a topping or snack for a dish, has a good taste, and has an appropriately deformed shape. Therefore, it is difficult to make a product with a crisp texture, and the development of such a new product is a research issue in the seaweed industry.

Therefore, an object of the present invention is to provide a processed algae food suitable as a topping for snacks and dishes, and a method for producing the same.

[0008]

That is, the present invention provides a processed algae product (hereinafter, a processed food product of the present invention, in which at least an algae and an additive are thermally deformed and entangled with each other by a heating and stirring treatment. Referred to as)).

According to the processed food of the present invention, since the algae and the additives are thermally deformed and entangled with each other by the heating and stirring treatment, the processed food has a complicated uneven surface and is cut into small wrinkles. It has a shape like a twist or a twist, and it can be finished into a food with a good texture, and its taste and texture can be enhanced by the addition of additives.

The present invention also provides a method for producing a processed algae product, which comprises at least a step of mixing algae and additives and a heating and stirring step of stirring the mixture under the action of a heating medium (hereinafter referred to as the present invention. (Hereinafter referred to as a manufacturing method).

According to the production method of the present invention, a mixture of algae and additives is heated and stirred under the action of a heating medium, so that the mixture can be thermally deformed to form a entangled processed food. Therefore, the processed food can be produced with good reproducibility.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be specifically described below.

The processed algae food of the present embodiment (hereinafter, also referred to as processed seaweed food) is a processed seaweed food prepared by adding, for example, sesame oil and salt to the original algae of rock seaweed. The raw material for this is a seed that is native to China, and the one that has been cultivated in Japan is used. As in the manufacturing process described above, the working process in this case is also such that the seaweed net is pulled up, the seaweed is picked, washed, dehydrated, and then dried. Then, the finished nori seaweed is loosened manually. The seaweed thus loosened is called dried rose.

Further, the object to which the present embodiment is applicable is not limited to seaweed, and includes, for example, hijiki, kelp, wakame seaweed, and the like. Hereinafter, rock nori (hereinafter referred to as nori) will be described. .

FIG. 1 shows a method of manufacturing a processed seaweed food according to the present embodiment in the order of steps.

First, in step 1, since the raw material in a dried state is a mass of raw seaweed algae (water content about 3%), it is loosened to a size of about 2 cm square.

Next, in step 2, the raw material loosened in the previous step is weighed and a single treatment amount is stored in a tray. In the case of this embodiment, the drum volume of the manufacturing apparatus described later is 7
Since it is 5 liters and the effective volume that can be treated is 20%, the amount of treatment per treatment is 250 g.

Next, in step 3, 125 cc of sesame oil (preferably 100 to 100 g) is added as an amount suitable for 250 g of seaweed.
Add 150 cc) and stir so that the surface of the seaweed is thoroughly spread. It is desirable to determine the addition ratio of sesame oil by gradually increasing the amount of sesame oil and determining the adsorbability of sesame and salt. The additives are not limited to sesame oil, and other edible oils (eg, corn oil, safflower oil) may be used.

Next, in step 4, the raw material 20 stirred in the previous step is charged into the drum 15 of the manufacturing apparatus 10 as shown in FIG.

Next, in step 5, as shown in FIG. 3, while rotating the drum 15 charged with the raw material, the charged raw material is heat-treated with hot air at 180 ° C. In this case, since it is possible to bring out the texture and taste by baking more strongly than the normal baking (general baking of seaweed), 3 at 180 ° C
It is desirable to bake for a minute.

Next, in step 6, after confirming that the seaweed is sufficiently burnt, it is taken out from the apparatus. In this case, sesame oil (125 cc) added to 250 g of the raw material was added to 326 g.

Next, in step 7, salt (preferably 8 to 11% by weight) is sprinkled. In this case, the seaweed was agitated while sprinkling with 35.0 g of roasted salt, and the seaweed was sprinkled so as to mix well.

Through the above steps, a product (product weight 360 g) as a processed seaweed food is completed. As a result, the fragrant scent of sesame oil brings out the subtle savory flavor of the seaweed and has a light saltiness, so that it is possible to produce a processed seaweed food suitable for snacks or toppings for various dishes.

FIG. 4 schematically shows an apparatus for producing the processed seaweed food (hereinafter, sometimes referred to as an apparatus) in the present embodiment.

The apparatus shown in FIGS. 2 and 3 is constructed as shown in FIG. That is, the device 10 has a main body 11, a control unit 12, and an exhaust unit 13, and a front surface of the main body 11 is
Door 14 having a viewing window 14a with transparent glass attached in the center
Is provided. Inside the main body 11, a rotary drum 15 driven by a motor arranged rearward is arranged, an inner surface 17 of the rotary drum 15 has a wavy circumferential cross section formed in the longitudinal direction thereof, and a front surface of the rotary drum 15 is formed. A lid 16 having a viewing window 16a to which transparent glass is attached is provided.

A circuit for driving and controlling the device 10 and a hot air source are arranged inside the control unit 12, and hot air from the hot air source is supplied from the hot air inlet 23 of the main body 11 to the rotary drum 1.
It is irradiated to 5. The heating conditions are 160 to 180
C., preferably 3 to 5 minutes. The operation of each of these parts is operated on the operation panel 22 (see FIGS. 2 and 3).

The radiated hot air passes through the rotary drum (having air permeability) 15 and, after heating the charged raw material 20, is discharged from the exhaust port 13a of the exhaust unit 13. In this case, an exhaust fan may be provided in the exhaust unit 13 in order to increase the introduction efficiency of hot air.

FIG. 5 is a detailed view of the inside of the main body 11.
As shown, a shaft 2 extending from a drive source (not shown)
1 is provided with a plate plate 27, and stud bolts 28 fixed to the plate plate 27 penetrate four peripheral portions of the rotary drum 15 and are fixed by nuts 29 on the front surface of the rotary drum 15 to rotate the plate. The drum 15 is supported by the shaft 21 in a cantilever structure, and in this state, it is positioned inside the housing 18 that covers the rotary drum 15.

The rotary drum 15 is made of a material having high air permeability (for example, a mesh, a punching plate, or a porous member), and the hot air H introduced from the hot air introduction port 23.
Is sprayed onto the outer peripheral surface of the rotary drum 15 from a notch portion 18 a formed in the housing 18. Therefore, hot air H
While intruding into the rotary drum 15 while filling the gap 24 by the pressure, the raw material 20 (not shown in FIG. 5) contained in the rotary drum 15 is heated, and further, from inside the rotary drum 15, The hot air H emitted from the cutout portion 18b formed in the housing 18 is discharged to the outside via the upper exhaust portion 13.

Further, the periphery of the lid 16 of the rotary drum 15 is bolted to the drum body, and about 2/3 of the lid 16 is formed so as to be openable and closable by the hinge 16b, so that the raw material 20 can be put in and taken out by this opening and closing. It has become.

The heating principle of such a configuration is shown in FIGS. 6 and 7.

First, FIG. 6 is a schematic view showing the front surface of the apparatus before feeding the raw materials, and shows the wavy surface of the inner surface 17 of the rotary drum 15 through a viewing window (not shown). Then, the raw material is put into the rotary drum 15 and subjected to heat treatment while blowing hot air (in this case, 180 ° C. for 3 minutes) on the rotating rotary drum 15.

As shown in FIG. 7, the inner surface 17 of the rotary drum 15 has a triangular concave-convex circumferential cross section formed in the longitudinal direction of the drum, and is made of a material having high air permeability as described above. The maximum inner diameter D is about 900 mm. Therefore, by the rotation of the rotary drum 15, the unevenness of the inner surface 17 functions as a stirring means.

Housing 1 covering rotating drum 15
In No. 8, since the portions corresponding to the hot air introducing passage 23 and the exhaust portion 13 are formed as the cutout portions 18a and 18b, the hot air H introduced from the hot air introducing passage 23 is blown straight to the outer circumferential surface of the rotary drum 15. Put on. Since the gap 24 between the rotary drum 15 and the housing 18 is small, the hot air H also enters this gap 24, but most of the hot air H passes through the breathable drum surface and is introduced into the rotary drum 15 and discharged.

Raw material 20 charged into the rotary drum 15
Is a mixture of sesame oil added to the raw material in a loosely dried state, and is therefore in a semi-kneaded state.
Unevenly distributed on the inner surface of. Therefore, even if the rotary drum 15 rotates, the uneven distribution region expands, but the state where the rotary drum 15 adheres to the inner surface 17 is maintained.

However, as shown in the drawing, the raw material 20 introduced by the hot air H and unevenly distributed on the inner surface 17 of the rotary drum 15 and attached thereto is dried as it is heated, and the raw material 20 attached to the inner surface 17 is removed. Separated from the inside and blown up,
Gradually it becomes small pieces and is scattered. Furthermore, since the rotary drum 15 is rotating, the unevenness of the inner surface 17 causes stirring,
The fragmentation is promoted.

A microwave introduction mechanism may be installed in the apparatus 10 of the present embodiment, and the raw material 20 to be charged may be added.
Depending on the state and type, the microwave M can be used together as shown in FIG. By heating the raw material 20 also from the inside using the microwave M, it is possible to improve the heating efficiency and the productivity as compared with the case where the raw material 20 is heated only from the outside with hot air.

However, since the seaweed (dried in a dried state) has a low water content, it can be sufficiently heat-treated with only the hot air H, and it is not necessary to use the microwave M together, but for example, hijiki or konbu is used as the raw material. When used as, it is better to use the microwave M together.

FIG. 8 shows a state in which the material is heated and agitated into small pieces according to the above principle. FIG. 8A is an external view of the raw material in the process of fragmentation, and FIG. 8B is an external view of the fragmented state.

That is, in the fragmentation process, FIG.
As shown in Fig. 5, viscous seaweed fibers adhere to each other and are entangled with each other, and in this state, adhere to the inner surface 17 of the rotating drum 15, and when separated from the inner surface 17, they become plate-like and scattered inside the drum. To do. Then, as the rotary drum 15 rotates, it is agitated by the irregularities of the inner surface 17, further blown up by hot air and floats, and is uniformly baked in a short time and efficiently. As a result, as shown in FIG. 8B, the plate-shaped small piece 25 is thermally deformed and twisted to be wrinkled, and entangled with each other, and especially, the edge is curled as if curled.

Such a shape is the shape that the present embodiment aims at, and this can be realized by the manufacturing process described above, and the target product 25A having a water content of about 1.9% is completed. I was able to.

In the process of completing the desired product according to the above embodiment, the heating temperature and the heating time are changed,
The four tests shown in the following table were conducted. In the following table, “preliminary” means addition of sesame oil before heating, and “post-addition” means addition of sesame oil after heating.

[0043]

[Table 1]

[Table 2]

As a result of this test, according to test 4 in the above table, sesame oil was added in advance (step 3 in FIG. 1),
It was found that the method of heating at 180 ° C. for 3 minutes to bake is the best, which supports the validity of the method for producing the processed food according to the present embodiment.

The above-described present embodiment can be variously modified based on the technical idea of the present invention.

For example, the additive may be other than sesame oil or salt, and the raw material is not limited to seaweed, but may be algae other than seaweed, such as hijiki, seaweed, and kelp, or vegetables may be used.

Further, the apparatus of the embodiment has the rotary drum 1
The inner surface 17 of No. 5 was provided with irregularities having a triangular cross section, but other shapes may be used. For example, a drum (rotary or fixed type) having an inner surface without irregularities has a plate-like or polygonal cross section. Means (rotary or stationary) may be provided.

Further, the manufacturing method and apparatus shown in the embodiment may be appropriate other than the embodiment.

[0049]

As described above, according to the processed algae food and the method for producing the same of the present invention, since the algae and the additives are thermally deformed and entangled with each other by the heating and stirring treatment, the processed food has complicated irregularities.
