Abstract
麹納豆(塩納豆, 浜納豆, 大徳寺納豆)中の全カルシウム量, 遊離カルシウム量の分析, および全燐酸, 遊離燐酸, フイチン酸, 硝酸イオン含量の定量を行った。これと比較するため糸引き納豆, 米味噌, 八丁味噌, 金山寺味噌の分析・定量も行った。塩納豆は外観はほぼ糸引き納豆に近いものではあるが, 麹味噌の特徴をももっている。浜納豆, 大徳寺納豆は発酵によりフイチン酸含量が減少しており, 硝酸含量は味噌類と同程度であった。これらの結果から麹納豆は糸引き納豆よりカルシウムをはじめZn, Mg, Feなどの利用効率を改善しているものと考えられる。
Analyses of total and free calcium, total and free phosphate, phytate and nitrate contents in various Koji Nattoes, Shio-natto, Hama-natto and Daitokuji-natto, were carried out. Itohiki-natto, Rice-Koji Miso, Hattyo Miso, Kinzanji Miso and Kinako were also analysed as samples for comparisons. Sio-natto had an appearance of Itohiki-natto, and was also alike to Koji Miso. Hama-natto and Daitokuji-natto had less phytate content than soybean, so that these Koji Nattoes are good to take nutritional minerals such as calcium, magnesium, iron and zinc for human nutrition.
