- Boneless Fish
The nihongo|Boneless Fish|骨なし魚|Hone-nashi Sakana is a
fish -based frozen food invented by Dairei Corporation (大冷株式会社) ofJapan in1998 . It is essentially a fish that has been scaled, gutted and deboned by a skilled worker before being reassembled to look like a dressed fish (gutted and with itshead andfin s removed). The fish is then flash frozen and packaged. It remains uncooked.It is possible to use this process to manufacture a boneless fish with its head and fins intact. However, this is not very practical.
Purpose
The Boneless Fish was initially intended to feed three groups: the elderly, hospital patients, and schoolchildren. It differs from an ordinary frozen fish fillet, as the Boneless Fish looks just like a dressed fish. It is also cooked in the same manner as an ordinary fish.
Dairei began to market it to families in
2002 . Aside from being easy to prepare, cooking boneless fish at home generates very little kitchenwaste .Production
The production of the Boneless Fish is labor intensive. Dairei set up HACCP-certified factories in
Thailand ,China andVietnam . The workers cut open the fish and use a pair oftweezers to remove the bones. The end product is then examined to make sure that it is free of bones and then "glued" together using a food-gradeenzyme produced byAjinomoto .This binding agent is a
transglutaminase (product name: Activa TG-B) which is separated from a culture of "Streptoverticillium mobaraense ". It works by binding thecollagen 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 success of Boneless Fish inspired another technology-intensive product, "Fish with Delicious Bones" (骨までおいしい魚; "honemade oishii sakana"), on sale since
2004 . The fish, in the form of a butterfly fillet, is prepared by apatent pending process that uses heat and pressure to tenderize fish bones. It is said the entire fish, including the head and fins, becomes completely edible, much like what happens to cannedsardine s. It is a jointinvention of Maruha Corporation (株式会社マルハ) and Miyajima Soysauce Corporation (宮島醤油株式会社).Another, chimeral, product is the "Cold Set Bound Fish
Kebab s" made from alternating layers ofsalmon andcod which are "glued" together by transglutaminase.External links
