Description

The present invention relates to a method for removing and processing a thin skin (commonly known as red skin) of Rhopilema esculentum and a thin skin removing tool.

The edible Rhopilema esculentum that can be found in the waters near Japan, especially the Ariake Rhopilema esculentum, has a thin skin, commonly known as red skin, attached to the inner part of the circular umbrella. Unless this thin skin is completely removed, it cannot be commercialized as an edible jellyfish, so it is generally scraped off by hand using a spatula-shaped jig in China. Since there are no jellyfish fishermen and no processing factories in Japan, Chinese fishing boats are fishing for jellyfish in the waters near Japan, and they are processing in China.

By the way, if the thin skin is manually scraped off using a spatula-shaped jig, the peeling process takes time, which causes a disadvantage that the producer is not profitable. In particular, recently, high-quality Rhopilema esculentum has few resources due to over-picking or early picking, and although there are rarely large ones, most of them are small ones with a diameter of about 40 cm or less, and are small. I strongly hope that I don't want to spend time on the process of scraping off the thin skin of jellyfish.

However, at present, the method and the removing tool for efficiently scraping or peeling off the thin skin of Rhopilema esculentum have not been developed.

No known patent document is found.

By the way, also in Bizen jellyfish, the inner 2/3 of the radius length from the center to the outer peripheral edge is soft fleshy, and the outer peripheral edge 1/3 is hard fleshy. Since there is a step and it is slightly curved inward, and the thin skin is firmly attached, it is extremely difficult to mechanically scrape or peel off the thin skin using an instrument. It has a problem.

Therefore, the soft part and the hard part with different meat quality are sorted first, and the soft meat part is hard while being able to efficiently scrape or peel off the thin skin using special equipment according to domestic demand. The meaty part is intended to be able to be exported and provided with a thin skin to meet the overseas demand that prefers it.

The method for processing Rhopilema esculentum according to the first invention of the present invention is a method for processing Rhopilema esculentum with a thin skin, and has an inner portion 2/3 of the radius length from the center of the circular Rhopilema esculentum to the outer peripheral edge portion. The part having a different meat quality from the outer peripheral edge portion 1/3 is separated and sorted into a hard part and a soft part of the meat quality, and the sorted hard part of the meat quality is mainly used for export with a thin skin as it is, and the meat quality is said. The soft part of Rhopilema esculentum provides a method for processing Rhopilema esculentum, which is characterized by removing the thin skin with a special removing tool and then cutting it in a non-linear manner so as to form a strip longer than the diameter of the jellyfish and having a required width. is there.

In the invention of the processing method, the required width is included in the range of about 2 to 8 mm as an additional requirement.

Further, in the second invention of the present invention, in the special removing tool for removing the thin skin of the jellyfish, the tip of the grip portion is formed in a Y shape, and the blade portion is attached to the Y-shaped tip portion. The blade portion has rising portions at both ends and is composed of a guide portion fixed with a bolt and a blade, and a rectangular engaging hole is provided in the rising portion of the guide portion, and the engaging portion of the grip portion is provided with a rectangular engaging hole. The present invention provides a removing tool for removing a thin skin of a jellyfish, which is characterized in that a Y-shaped tip portion is loosely engaged and engaged to rotate slightly.

According to the processing method and the sorting method according to the present invention, the parts having different meat qualities are separated, the thin film is removed, and the parts are sorted according to the difference in meat qualities. And by cutting to the appropriate size according to the needs of consumers (including consumers), the texture and texture will not be mixed, and the seasoning and texture will be uniform. It has the excellent effect of being able to provide processed jellyfish that can meet the needs of vendors and consumers.

It is a bizen jellyfish with a thin skin used in the processing method (removal and cutting of a thin skin) of the present invention, and is a plan view schematically shown for explanation. It is a top view which showed the fleshy hard part (outer peripheral part) which separated the Bizen jellyfish by the boundary line. It is a top view which showed the soft part (inner part) of the fleshy body which separated the Bizen jellyfish by the boundary line. It is a perspective view which showed the remover which peels off or scrapes a thin skin which concerns on this invention. FIG. 5 is a cross-sectional view taken along the line AA of FIG. 4 showing a situation in which the thin skin is removed using the same removing tool. It is a top view which showed the situation of an example which cuts the soft part of the flesh from which the thin skin was removed. The situation of another example of cutting the soft part of the fleshy body from which the thin skin was removed is shown. The figure (a) shows the situation of folding in half, and the figure (b) shows the situation of cutting in four. It is a plan view.

Next, the present invention will be described in detail based on the specific embodiments shown in the illustration. FIG. 1 is a plan view showing the inner part of the umbrella by separating the foot part from the umbrella part of the Bizen jellyfish with a thin skin, and is about 2 of the length from the center 0 to the peripheral portion of the Bizen jellyfish 1. At the length position of / 3, as shown by the broken line 2, the meat quality is different between the outside and the inside. That is, the outer 1/3 from the broken line 2 is commonly called "ear", and its meat quality is a crunchy hard part 3 when chewed, and this hard part 3 is probably a jellyfish swimming and moving. It was also found to be a kind of delicate fibrous tissue, as it seems to have developed due to the occasional fanning movement. Then, it was confirmed that the meat quality of the inner part from the broken line 2 was the soft part 4 which was sticky and pre-prepared when chewed. In the figure, 2a is a portion where the foot portion is separated.

It was found and confirmed that the ratio of the above-mentioned 1/3 hard portion 3 and 2/3 soft portion 4 did not change at all regardless of whether the jellyfish was large or small.
Therefore, the part of the broken line 2 separates the hard part 3 and the soft part 4, and by this separation, the first grade product is classified into the highest quality (1F) and the first grade product is the highest quality (1FF). It shifts to the processing process of. That is, as shown in FIG. 2, the hard part 3 after separation is sorted as a first-class high-quality product (1F), and the hard part 3 is eaten by Chinese people, so a thin skin is attached in the separated state. It is mainly exported to overseas (China) as it is, and as shown in Fig. 3, the soft part 4 has a small diameter, but regardless of the subsequent chemical work, it is the highest quality first-class product ( 1FF) and processed for domestic consumption. It was confirmed that the thin skin in the hard portion 3 was strongly stuck and could not be easily peeled off even with a spatula-shaped jig.

Since the soft portion 4 still has a thin skin, the thin skin is removed by using the special removing tool 5 shown in FIG.
That is, the special remover 5 has a blade portion 7 attached to the Y-shaped tip portions 6a and 6b of the grip portion 6, and the blade portion 7 has a guide portion 8 and a blade 9 at both ends. The rising portions 10 and 11 are fixed by bolts 12, and the Y-shaped tip portions 6a and 6b of the grip portion 6 are loosely engaged with the rectangular engaging holes 13 provided in the rising portion 10 of the guide portion 8. It is attached so that it can rotate slightly.

By attaching the grip portion 6 to the blade portion 7 in this way, as shown in FIG. 5, the blade portion 7 of the remover 5 abuts (contacts) the surface of the bizen jellyfish 1 having the thin skin 14 of the soft portion 4. By moving (manipulating) in the direction of arrow b, the thin skin 14 can be efficiently peeled off by the blade portion 7. In this case, since the thin skin 14 does not exist in the separated portion 2a of the foot, the thin skin 14 can be efficiently peeled off by operating (moving) the removing tool 5 along the arc. Since the bottom surface of the blade 9 is wide and the entire blade abuts on the body of the jellyfish, the cutting edge does not bite into the body of the jellyfish.

Then, as shown in FIG. 6, the soft portion 4 from which the thin skin 14 has been peeled off has a strip shape with a required width (within a range of about 2 to 8 mm) for the domestic market and a non-linear shape longer than the diameter, for example. It can be cut 15 in a spiral shape, then cut to a length of 30 cm or more, labeled as the highest quality (1FF) of a first-class product, and put on the market. In addition, as shown in FIGS. 7 (a) and 7 (b), the soft portion 4 is folded from two to four, one side (radius length) of the four-fold fold is cut, and then the whole is circled. By cutting 16 in an arc shape, about half can be cut longer than the diameter, and the latter half or less can be appropriately cut 16a, so cut into appropriate lengths and shorts according to the use as jellyfish dishes. You can do it. If you cut a circle without cutting one side of the quadruple, cut the relatively large circle into a strip, and fold the small circle in half and tie it into a figure eight. It can be sold as a "matchmaking jellyfish".

In any case, in the processing method of Bizen jellyfish with the thin skin 14, the hard part 3 and the soft part 4 are sorted in advance as described above, and in particular, for the domestic market, the thin skin 14 is separated by a special removing tool 5. It has been removed, and as described above, it is longer than the diameter of the jellyfish, or various cutting means can be applied, and the processed soft portion 4 has a uniform pre-prepared feeling that the taste is easy to get on when seasoned and the taste is felt. On the other hand, the hard portion 3 may be exported overseas with the thin skin 14 attached, or when sold domestically, the thin skin 14 may be removed and cut by an appropriate cutting means. It is possible, and even if it is seasoned, the taste is difficult to get on, it has a uniform crispness, and one of them can be appropriately selected according to the taste of the consumer.
Before cutting, the hard part 3 and the soft part 4 are sorted and placed separately, so that the hard part 3 and the soft part 4 are cut after the cutting. Not to be confused with processed products, it is extremely easy for handlers and consumers to make choices.

In the method for processing Bizen jellyfish 1 having a thin skin 14 according to the present invention, 1/3 of the peripheral portion where the meat quality of the jellyfish is hard is cut into a circular shape, the hard portion 3 and the soft portion 4 are sorted, and then the hard portion 3 and the soft portion 4 are separated. By handling them separately, the meat quality sorted according to the needs of the processor and the restaurant is selected, and the thin skin is removed by the removing tool 5 and then cut. Depending on the difference, the jellyfish's original pre-prepared and crunchy feeling is brought out to make it an edible jellyfish, so the processed jellyfish can be widely used not only as Chinese food but also as Japanese food according to taste. It was confirmed that the thin skin of the hard portion 3 can be efficiently and easily peeled off by the removing tool 5.
