Description

[0001]
[Technical field to which the invention belongs]
The present invention processes a tuna ovary that has been discarded until now, and a processed tuna ovary processed food that has a petal-like texture, a petal-like flower shape, a star shape, or a human shape that cannot be imagined from the original form. The purpose is to provide.
[0002]
[Prior art]
The world's tuna catch is about 1.9 million tons (1995) and consumption in Japan is 710,000 tons. Usually, about 75% of the tuna is used for food, and the head and built-in are used as feed or are disposed of. In particular, the built-in has not been found to be useful, with 14,000 tons being disposed of offshore and other. The ovary occupies 1600 tons, varies depending on the type, has a length of 40 to 20 cm, and a diameter of 10 to 5 cm. It has a shape as shown in FIG. Such a large size is not only bad in appearance but also difficult to handle, and most of them are discarded offshore without being processed and used as food, which is considered one of the causes of marine pollution.
[0003]
[Problems to be solved by the invention]
However, even if the appearance is bad, the ovary itself has a crisp texture, and depending on the processing method, it may be used as a unique delicious food. Therefore, various processing methods for tuna ovaries have been studied.
[0004]
[Means for Solving the Problems]
An object of the present invention is to solve the above-mentioned problems. The structure of the present invention is to cut a tuna ovary into 4 to 11 mm long slices, or cut the sliced ovaries in a fan shape so that the central angle is 60 ° or more. By heating this ovary piece, the outer skin moves to the center due to the thermal contraction of the ovary skin, and the ovary diverges and uses a reversal phenomenon in which the ovary branches and arranges in the shape of a petal outside the outer skin. It is characterized by a flower shape with a flower petal, and the reversal operation is performed in warm water or with steam to make canned foods, retort foods, or fried foods.
[0005]
That is, the tuna ovary has an egg covered with an egg membrane. The egg membrane itself is extremely shrinkable when heated. The circumference of the sliced tuna ovary piece is covered with an egg membrane. As shown in FIG. 2, when the sliced tuna ovary piece is thin, the egg membrane contracts extremely and collects in the center of the tuna ovary piece. I come to. At that time, the eggs are bound to each other and do not boil, but due to the large reversal that the eggs in the center move outward and the eggs in the periphery move to the base, the egg masses are separated at moderate intervals. Inverts into a petal shape around the egg membrane. This phenomenon is also seen when the sliced tuna ovary piece is divided into four segments from the center in a fan shape as shown in FIG. Grotesque tuna ovary has a three-dimensional petal shape that improves its appearance, tastes good, and the ovary itself is naturally delicious, so it has been successfully used as a favorite food.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of a tuna ovary, FIG. 2 is a perspective view showing a state in which the ovary is cut into circles, FIG. 3 is a perspective view of an ovary piece in which the chopped ovaries are cut into quarters, and FIG. FIG. 5 is a plan view showing the inverted state of FIG. 3.
[0007]
When the present inventors cut the tuna ovary 1 and put it in boiling water, as shown by the arrows in FIG. 2, the egg membrane 2 moved to the center, and the egg 3 was pushed out of the egg membrane 2 and several We found a phenomenon that branched into pieces into petals as shown in Fig. 4 and changed from a first shape to a beautiful shape that could not be imagined. After that, it is expressed as petal shape, but it is a three-dimensional unique shape that can only be expressed as a star shape, human shape, autumnal leaf shape, turbine shape, etc. An oval egg mass extends outward.
Furthermore, when the cut ovary was cut into a fan shape from almost the center and poured into boiling water, it was found that the ovary piece showed a petal-like shape even if it was not completely covered by the egg membrane. That is, FIG. 3 is a perspective view in which a sliced ovary piece is divided into four equal parts from the central part. In this case, the ovary piece is inverted to obtain a petal-like shape with a missing portion as shown in FIG. Eggs contract and bind to each other, with little boiling.
The present invention remarkably enhances the commercial value of tuna ovary using this phenomenon.
[0008]
Most of the tuna ovaries that are used in the present invention are frozen, but near sea products are used while being refrigerated. The ovaries are cut perpendicular to the length. If the ovary piece is too thick, the reversal phenomenon does not occur even when heated. It is difficult to cut extremely thin and is generally 0.3 to 15 mm, preferably 5 to 10 mm. The reversal phenomenon occurs in a thin disc-shaped ovary piece covered with the egg membrane 2, but a part of the cut ovary is missing, half-folded, and further fan-shaped, divided into four equal parts from the center, It is also caused by ovary pieces with a central angle of 60 ° or more. Even if it is fan-shaped, when it is cut from the central part and the central angle is less than 60 °, it often boils, the inverted ovary is difficult to branch, and a petal-like appearance is difficult to obtain.
[0009]
In order to cause the reversal phenomenon, moisture is required and the process is usually performed in warm water. In order to invert reliably, 90 degreeC, Preferably 95 degreeC or more is required. When warm water is the seasoning liquid, a tuna ovarian simmered inversion is obtained. It can also be reversed in water vapor. In addition, the canned and retort pouches contain tuna ovary pieces that have been inverted by adding seasoning liquid and tuna ovary pieces before inversion, other ingredients if necessary, sealed in cans and heat-resistant packaging bags, and heating as they are. Can be manufactured.
[0010]
In the present invention, a temporarily processed product that is simply inverted and not seasoned also belongs to the processed food of tuna ovary of the present invention. That is, if it is inverted, it is sufficiently heated and can be used as it is depending on the taste.
Alternatively, the inverted tuna ovary pieces can be put into heated cooking oil to make deep-fried foods such as deep-fried food, deep-fried food, and tempura. These fried foods can be further boiled, and the cooking methods are various.
