【発明の詳細な説明】
〔産業上の利用分野〕
本発明は、中〜大型のシュリンプ・ブローン類、特にク
ルマエビ等の高価なエビ類の冷凍方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a method for freezing medium to large-sized shrimp and shrimp, particularly expensive shrimp such as black shrimp.
従来の冷凍エビは、概ね１．３または１．８ ｋｇに規
格化された注水ブロック凍結品である。このエビの冷凍
方法は緩慢冷凍であるため、エビの筋肉細胞内に大きな
氷の結晶ができ、それが原因で品質劣化を来す６例えば
筋肉細胞の物理的破壊による食感の悪化や、解凍した際
のドリップの増加によるうま味成分の流出などがある。Conventional frozen shrimp are water-filled block frozen products standardized to approximately 1.3 or 1.8 kg. Since this method of freezing shrimp is slow freezing, large ice crystals form inside the shrimp's muscle cells, which causes quality deterioration. When brewed, umami components may leak out due to increased drip.
また、小売り用の小口包装（コンシェマーバック）にす
るために、上記凍結ブロック規格品を一度解凍して小分
けし、これを包装し直している。In addition, in order to make small-lot packaging for retail sale (consumer bag), the frozen block standard product is thawed, divided into small portions, and then repackaged.
従って包装に手間が掛かってコスト高の一因となり、う
ま味も失われてしまっているのが現状である。Therefore, the current situation is that packaging takes time and effort, contributing to high costs, and the umami flavor is also lost.

包装ができないため、包装の途中や、輸送、保管時の取
扱いの際、ひげ、膨脂、腹足、尾扇部等の突出部が欠落
して商品価値を損ねることが多かった。As a means to solve the above problems, shrimp are rapidly frozen one by one, but if shrimp are quickly frozen as is, their backs will become arched and their bodies will bend.The fresher the shrimp, the better. In addition, the faster the freezing, the more the shrimp's body becomes bent. Not only does it look inferior as a product, but it is also difficult to package, making it impossible to wrap it perfectly. During storage and handling, protruding parts such as whiskers, blubber, abdominal legs, and tail fans were often missing, reducing the product value.
そこで、冷凍によってエビの体が曲がってしまわないよ
うに、また、ひげ、膨脂、腹足、尾扇部等の突出部を整
えた形態に保持して急速冷凍する方法が提案されている
（特公平１−１９８５３号公報参照）。Therefore, a method has been proposed in which the shrimp body is not bent during freezing and the protruding parts such as whiskers, blubber, gastropods, and tail fan are maintained in a well-organized form during rapid freezing. (See Japanese Patent Publication No. 1-19853).
その内容は、冷凍すべきエビを載せる金属製トレーを可

レーに張り付き固定させる。The contents include: cooling the metal tray on which the shrimp to be frozen is placed to as low a temperature as possible (preferably below -20°C);
On the other hand, the shrimp to be frozen is immersed in cold water to wet the surface of the shrimp, and the body of the shrimp is stretched straight, and the whiskers, blubber, abdominal legs, tail fan, etc. are shaped into a well-shaped tray. On top of the! By doing so, the water adhering to the surface of the shrimp freezes almost instantaneously, causing the shrimp to stick to the tray in an elongated position and become fixed.
次いで、エビが張り付いているトレーを急速冷凍機に入

されるものである。Next, the tray with the shrimp stuck to it is placed in a rapid freezer to freeze the shrimp, and then the frozen shrimp are peeled off from the tray one by one while in that stretched position to form another package with a shrimp-shaped frame. It is stored in a container and stored at low temperature before being sold.
