Boneless Fish

Last updated • 2 min readFrom Wikipedia, The Free Encyclopedia

Boneless Fish is a fish-based frozen food brand and grocery product, the process in the production of which was invented by Dairei Corporation (大冷株式会社) of Japan in 1998. It is essentially a fish that has been scaled, gutted and deboned by a skilled worker before being reassembled with a transglutaminase to look like a dressed fish (fish gutted and with its head and fins removed). The fish is then flash-frozen and packaged, remaining uncooked.

Contents

It is possible to manufacture a boneless fish with head and fins intact, but it had been found to be impractical.[ citation needed ]

Purpose

The Boneless Fish product was initially intended to feed three groups: the elderly, hospital patients, and schoolchildren. It differs from an ordinary frozen fish fillet in that the content of a Boneless Fish pack looks just like a dressed fish. The product is cooked in the same manner as an ordinary fish.

Dairei began to market it to families in 2002. It had been found to be advantageous to consumers in that aside from being easy to prepare, cooking the brand's boneless fish at home—as against the usual market fish—generates a very small amount of waste.

Production

The production of Boneless Fish is labor-intensive. Dairei set up HACCP-certified factories in Thailand, China and Vietnam, where its workers cut open the fish and use a pair of tweezers to remove the bones. The end product is then examined to make sure that it is free of bones and then "glued back together" using a food-grade enzyme produced by Ajinomoto.

The Ajinomoto binding agent used in Boneless Fish is a transglutaminase (product name: Activa TG-B) separated from a culture of Streptoverticillium mobaraense . It works by binding the collagen in the fish tissue. At temperatures under 5 °C, it may take several hours for the enzyme to do its job properly.

Similar products

The popularity of boneless fish inspired another technology-intensive Japanese product, "Fish with Delicious Bones" (骨までおいしい魚; honemade oishii sakana), which has been on sale since 2004. The fish, in the form of a butterfly fillet, is prepared by a patent pending [ needs update ] process that uses heat and pressure to tenderize fish bones. The entire fish, including the head and fins, becomes completely edible, much like what happens to canned sardines. It is a joint claimed invention of Maruha Corporation (株式会社マルハ) and Miyajima Soysauce Corporation (宮島醤油株式会社). [1]

Another similar product is "Cold Set Bound Fish Kebabs", made from alternating layers of salmon and cod "glued together" by transglutaminase. [2]

Transglutaminases are enzymes that in nature primarily catalyze the formation of an isopeptide bond between γ-carboxamide groups ( -(C=O)NH2 ) of glutamine residue side chains and the ε-amino groups ( -NH2 ) of lysine residue side chains with subsequent release of ammonia ( NH3 ). Lysine and glutamine residues must be bound to a peptide or a protein so that this cross-linking (between separate molecules) or intramolecular (within the same molecule) reaction can happen. Bonds formed by transglutaminase exhibit high resistance to proteolytic degradation (proteolysis). The reaction is
