教員からのメッセージ
水産物は人類にとって重要な食糧資源です。私たちの研究室は,水産物を食べることで得られる栄養学的利益(nutritional benefits)と発生する問題(Food safety risk)の理解につとめています。そして,利用・加工に伴う栄養成分の変化を念頭において,未利用水産資源の活用研究に取り組んでいます。

まず,(1)保蔵・調理・加工過程で起きるさまざまな化学反応が,主にタンパク質の機能に及ぼす影響を調べ,それを利用して水産資源に含まれる栄養・健康機能(nutritional benefits)を高度に利用するための方法を研究しています。また,(2)含有成分の化学的性質を利用して健康機能成分を効果的に摂取する方法を検討しています。

一方,他の食品と同様,水産物は食物アレルギー(Food safety risk)を誘引するタンパク質(アレルゲン)を含んでいます。500種類以上の水産物が消費されている日本は,諸外国よりも水産物アレルギーの有病率が高くなっています。そこで,摂取リスクの低減に貢献する学術情報の発信をめざし,(3)水産物アレルゲンの性状と消化・吸収動態を調べています。また同時に,(4)調理・加工工程でおきる化学変化が,水産物のアレルギー反応性に及ぼす影響を調べています。

Laboratory introduction 



Marine bioresources, such as fish, shellfish, and seaweed, are indispensable food resources for human beings. Therefore, it is important to understand nutritional benefits and food safety risk of fishery products. We are studying on application of underutilized marine bioresources with focusing on nutritional changes during food processing and preservation.
    • We are investigating the biochemical changes in seafood proteins due to various chemical reactions occurring during storage, cooking and processing, such as denaturation, proteolysis, and the Maillard reaction. We are also developing procedures for highly utilizing health beneficial components in marine resources, using such chemical changes.

 

    • Japan, where more than 500 types of marine products are consumed, is a country with a higher prevalence of seafood allergy than other countries, and various kinds of seafood are recognized as allergy causative foods, as the same as other natural food materials. Therefore, for the purpose of sending academic information that can contribute to reduction of seafood allergy risk, we are investigating biochemical properties and digestion/absorption kinetics of seafood allergens. Additionally, we are interested in the effect of cooking and processing on the allergenic reactivity of seafood allergens.
