Fisheries Research Agency Successfully Cracks Complete Genome of Bluefin Tuna
July 2, 2009
The Fisheries Research Agency announced on June 30 that the unprecedented cracking of the complete genome of bluefin tuna would materialize within this year.
In collaborations with Tokyo University as well as Kyushu University, the research agency is working on the unscrambling of the complete genome sequence and analyses of useful genes of bluefin tuna.
Bluefin tuna possesses 24 pairs of chromosomes; a size of the whole genome is estimated to be approximately eight million base pairs. The research agency is deciphering the fragmentation of the complete genome sequence of bluefin tuna, harnessing "the Next Generation Sequencer," which has hundreds of times higher processing capabilities than the conventional systems. From this time forward, the concrete decoding of where these base pairs are located on what chromosomes will be conducted and it is projected that the complete genome sequence will be deciphered before the end of the year.
The unscrambling of the complete genome sequence of bluefin tuna conveniently enables the production of breeds with advantageous genes, such as disease free varieties or a kind with a faster maturity rate. Moreover, the understanding of gene data makes it possible to discriminate origins and individuality of tunas harvested throughout the world. The following application possibilities are anticipated: 1) the development of sensitive resources management techniques; 2) the establishment of traceability from harvest to consumers; and 3) the development of functional foods and pharmaceutical products based on tuna's distinctive abilities, i.e. a high speed swimming capability, a heat-conservation mechanism, and a high DHA accumulation.

Liquid Freezer's Excellent Performance for Tuna Freezing
June 30, 2009
Kanesan Suisan, specializing in tuna processing, located in Edogawa, Tokyo under management of Keiji Ban, began utilizing a liquid freezer by Technican in June, realizing efficient tuna freezing.
The liquid freezer the company installed is a custom-made type with a conveyer belt. The freezer has a capacity for 300 kg per hour. A package of tuna with 3 cm in thickness takes 8 to 15 minutes to freeze. Placing a package in liquid alcohol at -30°C enables flash freezing, much faster than air-blast freezing, improving work efficiency.
Once an initial package is programmed in the freezer, every operation, from freezing to air-blasting alcohol, is done automatically.
A liquid freezer, which is eight to ten times more powerful than nitrogen freezing, delivers high performance in freezing of sushi and sashimi products. Maruha Nichiro Suisan's processing plant in Kagoshima Prefecture also installed a liquid freezer by Technican last year, making use of freezing filets of amberjack for sashimi.
A liquid freezer shortens a freezing time compared to an air freezer, making labor efficiency possible. Moreover, its abilities to fast-freeze liquid to 3 to 5 micrometers, smaller than a cell, and to keep cells undamaged, lessen the amount of drips, which contributes to the production of high quality end products, similar to fresh products.

Ministry of Agriculture, Forestry, and Fishery
Selects 40 Processed Products for Export Expansion
June 30, 2009
The Ministry of Agriculture, Forestry, and Fishery (MAFF) selected "40 processed food products with potential for exports recognized by the world" out of 253 products submitted for "Japanese foods expected for exports and favored by foreigners." Producers of the chosen products will be encouraged to participate in events organized by foreign embassies in Japan, aiming for export expansion.
The MAFF encouraged Japanese food manufacturers to submit their products, which would satisfy the following three conditions: 1) expiration dates that last more than four months; 2) products must be finalized in Japan; and 3) products must be commercialized commodities. Submitted products were tasted and voted by staff of foreign embassies and those from trading companies. The 40 select products constitute 20 processed foods, five confections, five refreshing beverages, and 10 condiments.
Marine products that passed were "Aburi Sanma" (broiled saury) by Abecho Shoten, Co. in Kisennuma, Miyazaki Pref.; "Madai Reikun" (cold-smoked red sea bream) by Ohmatsu-ya in Shima, Mie Pref.; "Chi-chiku" (chikuwa with cheese) by Kibun Shokuhin in Tokyo; "Sonomanma Chirimen" (whole baby sardine) by Seto Queen in Iyo, Ehime Pref.; "Saba no Reikun (cold-smoked mackerel) by Demer in Hachinohe, Aomori Pref.; "Nishin Umani: TERIYAKI FISH" (cooked herring) by Hiramatsu Shokuhin in Toyohashi, Aichi Pref.; and "Cheese Bo" (cheese and satsumage in stick) by Wakamatsu-ya in Ise, Mie Pref., a total of seven products.
