イカは、 生きている状態では、 透明な色彩を有し、 保護色のための色彩の変ィ匕 を生じる。 しかしながら、 死後、 イカは、 透明色から、 白色に変ィ匕するとともに、 時間とともに、 白色から、 灰色へと色彩が変化する。 また、 夕コも同様に、 視認 されない側の体表面の白色部分や、 切断した足部等の身体部分の断面は、 死後、 経時的に、 灰色へと変化する。 この色の変化は、 素材の変化又は変質と関連して おり、 白色から、 灰色への色彩の変化に応じて、 体表面から不快な臭気を発生す る。 これは、 捕獲されたイカ又は夕コの表面に付着している細菌によって、 体表 面から蛋白質の分解にともなって生じるものと考えられる。褐変若しくは黒化し ないできるだけ新鮮な色彩を保持したイカ又は夕コ (生きているか、 死んでいる かを問わず) を食したいとする要望が強いのに対して、 従来、 褐変若しくは黒ィ匕 することなく、 生きたままで入手する場合等を除いては、 新鮮な形でイカ又は夕 コを提供することは不可能であつた。 The squid has a transparent color in the living state, causing a change in color for a protective color. However, after death, the squid changes color from transparent to white and, over time, changes color from white to gray. In the same way, the white part of the body surface on the side that is not visible and the cross section of the body part such as the amputated leg change to gray over time after death. This change in color is associated with a change or alteration in the material, producing an unpleasant odor from the body surface in response to a change in color from white to gray. This is thought to be caused by the degradation of proteins from the body surface by the bacteria attached to the surface of the captured squid or squid. While there is a strong desire to eat squid or sardines (whether alive or dead) that retain the freshest possible color that does not brown or blacken, It was not possible to provide fresh squid or squid unless it was obtained alive without doing it.
従って、 これらのイカ又は夕コは、 新鮮さを保持するためには、 できるだけ生 きた状態で小売りや卸売りする必要がある。 しかしながら、 捕獲したイカ又は夕 コをそのまま輸送し、 販売時まで、 このような生きた状態で保存することは困難 であるとともに、 そのための設備が必要であり、 その状態に保つのに煩雑な作業 が要求される場合が多い。  Therefore, these squids or evening squids need to be retailed or wholesaled as fresh as possible to maintain their freshness. However, it is difficult to transport the captured squid or squid as it is and keep it alive until it is sold, and equipment is required for such a squid or squid. Is often required.
このため、 従来より、 簡易にかつそれでいて、 捕獲時の新鮮なイカ又は夕コの 色彩を保持できる方法が望まれていた。 発明の開示  For this reason, there has been a demand for a method that is simple and capable of retaining the color of fresh squid or squid at the time of capture. Disclosure of the invention
従って、 本発明は、 褐変若しくは黒化を効果的に防止し、 捕獲時又はそれに近 いの新鮮な色彩を有するイカ又は夕コを提供することを目的とする。 また、 変質 の防止を図り、 保存性に優れたイカ又は夕コを提供することを目的とする。  Accordingly, an object of the present invention is to provide a squid or a squid having a fresh color at or near the time of capture, which effectively prevents browning or blackening. It is also an object of the present invention to prevent deterioration and to provide squid or squid with excellent storage stability.
本発明者は、 上記課題を解決するために鋭意研究を行った結果、 生のイカ又は 夕コをアルカリ水溶液で処理し、 次いで、 アルカリ水溶液を洗浄するか、 又は中 和することにより、 上記課題を効果的に達成できることを見出し、 本発明に到達 したものである。 発明を実施するための形態  The present inventor has conducted intensive studies to solve the above-mentioned problems, and as a result, treating raw squid or squid with an alkaline aqueous solution, and then washing or neutralizing the alkaline aqueous solution, Have been found to be able to be effectively achieved, and have reached the present invention.

Example
以下、 実施例により本発明について更に詳細に説明する。  Hereinafter, the present invention will be described in more detail with reference to examples.
実施例 1 (ミズィ力の褐変又は黒化防止) Example 1 (Prevention of browning or blackening of Mizzi force)
以下の組成を有するアル力リ性処理液を準備した。  An alkaline processing solution having the following composition was prepared.
酢酸ナトリウム (緩衝剤) 38%  Sodium acetate (buffer) 38%
酸化カルシウム(アルカリ剤) 30%  Calcium oxide (alkali agent) 30%
ブドウ糖 (浸透剤) 32%  Glucose (penetrant) 32%
上記アルカリ性処理液、 10gを、 水に溶解して、 酸ィ匕カルシウム 0.3%、 H 11 の 1000mlのアル力リ水溶液を調製した。  10 g of the above-mentioned alkaline treatment solution was dissolved in water to prepare a 1000 ml aqueous solution of 0.3% of sodium chloride and H11.
生ミズイカ (山陰仙崎産) (体色は、 透明) をスーパ一にて購入した後、 直ち に、 上記のアルカリ水溶液に、 約 5 °Cにて、 適宜攪拌しながら、 1時間浸漬した。 次いで、 浸潰したミズイカを取り出し、 一旦、 流水で洗浄した後、 2 0 0 0mlの 水に約 5°Cで 3 0分間浸漬し、 水洗した。水洗ミズイカは、 次いで、 水を切った 後、 ポリプロピレン製の袋に入れ、 真空引きした後、 開口部を閉じて、 5〜1 0 °Cでの冷蔵保存 (ケース A 1 ) 、 及び 2 6〜3 3 °Cでの常温保存 (ケース B 1 ) を行い、 体色の変化及び変質の程度を観察した。 Raw watermelon (from Sanin Senzaki) (body color: transparent) was purchased at a supermarket and immediately immersed in the above alkaline aqueous solution at about 5 ° C for 1 hour with appropriate stirring. Next, take out the immersed watermelon, wash it once with running water, and then It was immersed in water at about 5 ° C for 30 minutes and washed with water. The water-washed watermelon is then drained, put in a polypropylene bag, evacuated, closed the opening, refrigerated at 5 to 10 ° C (Case A 1), and 26 to At room temperature at 33 ° C (case B 1), changes in body color and degree of deterioration were observed.
比較例として、 上記アル力リ水溶液処理及び水洗又は中和処理をしなかったこ とを除いて、 実施例 1と同様にして、 比較ミズイカ製品を調製し、 ポリプロピレ ン製の袋に入れ、 真空引きした後、 開口部を閉じて、 5〜1 0 °Cでの冷蔵保存 (ケース A C 1 ) 、 及び 2 6〜3 3 °Cでの常温保存 (ケース B C 1 ) を行い、 実 施例 1と同様に、 色変化及び変質の程度を観察した。  As a comparative example, a comparative watermelon product was prepared and placed in a polypropylene bag in the same manner as in Example 1 except that the above-mentioned aqueous solution treatment and the washing or neutralization treatment were not performed, and the product was evacuated. After that, close the opening and perform refrigerated storage at 5 to 10 ° C (Case AC1) and normal temperature storage at 26 to 33 ° C (Case BC1). Similarly, the degree of color change and deterioration was observed.
その結果、 ケース A 1では、 イカは、 保存開始当初の白色を 9日間に渡って、 保持しており、 ガスの発生による気泡の形成も観察されなかった。 これに対して、 ケース A C 1では、 保存開始当初の白色は、 保存後 3日目には、 やや灰色を帯び るようになり、 その変ィ匕は徐々に増大し、 9日目には、 全体が灰色となった。 ま た、 6日目には、 細かい気泡が発生し始め、 経時的に気泡の大きさが増大し、 ガ スの量が増えた。 そして、 経時的に 9日目には、 かなりのガスが袋内に溜まった。 また、 ケース B 1では、 保存開始時の白色は、 5日目まで保持され、 その後、 やや黄色味を帯びるようになつたが、 その後の色の変化は 9日目まで観察されな かった。 また、 ガスの発生は、 5日目ごろから、 細かい気泡として観察されるよ うになつたが、 その後の変化は全く観察されなかった。 これに対して、 ケース B C 1では、 保存開始当初で既にやや黄色味を帯びており、 保存期間の経過に伴つ て、 黄色に灰色が徐々に入り、 その大きさも拡大し始め、 9日目には、 全体が灰 色となった。 また、 保存開始当初から細かい気泡が発生し、 経時的に気泡の大き さも増大し、 ガスの量も徐々に増大し、 5日目には、 イカの厚みの 2倍程度にガ スが袋内に溜まり、 更に、 この量も多くなり、 9日目には、 ガスの量は、 イカの 厚みの 3〜4倍程度となった。 更に、 この場合、 5日目以降は、 イカの身だれが 発生し、 かつ増大し、 指で押すと、 身が崩れた。 As a result, in case A1, the squid retained the white color at the beginning of storage for 9 days, and no formation of bubbles due to gas generation was observed. On the other hand, in Case AC 1, the white color at the beginning of storage became slightly gray on the third day after storage, and the change gradually increased, and on the ninth day, The whole became gray. On the sixth day, fine bubbles began to form, and the size of the bubbles increased over time, and the amount of gas increased. And on the ninth day over time, considerable gas accumulated in the bag. In case B1, the white color at the start of storage was retained until the fifth day, and then slightly yellowish, but no color change was observed until the ninth day. From about the fifth day, gas generation began to be observed as fine bubbles, but no change was observed thereafter. On the other hand, in Case BC 1, the color of the storage was slightly yellowish at the beginning of storage, and as the storage period elapsed, yellow gradually turned gray and its size began to expand. In the first year, the whole became gray. In addition, fine bubbles are generated from the beginning of storage, the size of the bubbles increases with time, the amount of gas gradually increases, and on the 5th day, the gas in the bag is about twice the thickness of the squid. On the ninth day, the amount of gas became 3 to 4 times the thickness of the squid. Furthermore, in this case, after the fifth day, the squid It broke out and grew, and when I pressed it with my finger, I collapsed.
実施例 2 (ケンサキイ力の褐変防止) Example 2 (Prevention of browning of Kensakii power)
生のケンサキイ力 (函館産) (体色は、 透明色) を使用したことを除いて、 実 施例 1を繰り返した。  Example 1 was repeated except that raw Kensakii power (from Hakodate) (the body color was transparent) was used.
比較例として、 アルカリ処理及び水洗処理を行なわないことを除いて、 上記実 施例 2と同様に処理することによって、 比較ケンサキイ力を調製した。  As a comparative example, a comparative Kensaki force was prepared by treating in the same manner as in Example 2 except that the alkali treatment and the water washing treatment were not performed.
処理ケンサキイ力及び未処理ケンサキイ力に関する色及び異臭の変化は、 実施 例 1の絰時変化の進行に比べて約 1日早いことを除いては、 ほぼ実施例 1の場合 のミズイカと同様であった。  The changes in color and off-flavor of the treated and untreated kensakii powers were almost the same as those of the watermelon in Example 1, except that the change in color and off-flavor was about one day earlier than the temporal change in Example 1. Was.
上記の各実施例 1及び 2では、 イカを使用した場合の例を示したが、 イイダコ を使用した場合でも、 特に足の断面の白色の変化や、 異臭の発生は、 上記実施例 1及び 2の場合と同様の変化を生じた。  In each of Examples 1 and 2 above, an example in which squid was used was shown. However, even in the case of using octopus, the change in white color of the cross section of the foot and the generation of unpleasant odors were observed in Examples 1 and 2 above. A similar change occurred.
本発明の方法によれば、 生のィ力又は夕コをアル力リ水溶液により処理した後、 アル力リ処理材料に付着したアル力リ水溶液を洗浄するか、 又は中和することに より、 イカ又は夕コの褐変若しくは黒化を効果的に防止することができる。 また、 このような処理によって、 イカ又は夕コの長期保存性が大幅に改善された。従つ て、 これまで不可能と考えられていた、 死後においても、 新鮮な色彩の状態での イカ又は夕コの長期保存が可能となった。  According to the method of the present invention, after treating raw liquor or rice husk with an aqueous liquor solution, washing or neutralizing the aqueous liquor solution adhering to the liquor treated material, It is possible to effectively prevent browning or blackening of squid or evening squid. In addition, such treatment significantly improved the long-term storage of squid or squid. Therefore, long-term preservation of squid or squid in fresh colors has become possible even after death, which was previously considered impossible.
