Outline of Final Research Achievements |
The purpose of this study was to clarify how the nutritional availability of iron in meat and fish is affected by heat-cooking, using an in vitro digestion model and animal study. In this study, animal experiments suggested that the nutritional availability of iron in meat is reduced by heat-cooking. On the other hand, hemoglobin, the chemical form of iron in meat, showed no change in the nutritional availability of iron with or without heating. The results suggest that non-iron components reduced the nutritional availability of iron due to heat-cooking.

Academic Significance and Societal Importance of the Research Achievements |
これまでの食品に含まれる鉄の栄養有効性に関する研究は、加熱調理した食品を対象としていなかった。本研究は畜肉・魚肉に含有される鉄の栄養有効性が加熱調理によってどのように変化するのかを明らかにすることを目的として実施した。その結果、加熱処理によって鉄の栄養有効性が低下することがラットを用いた試験において示唆された。この成果は、実際の食生活に応用できる鉄の調理および補給方法に役立つデータとなりうる。
