摘要:When vitamin A, absorbed previously on defatted soybean flours, was mixed with another materials at the beginning of manufacturing process, the loss of vitamin A in this “Miso” was 10% approximately after fermentation, and the decrease of vitamin A content during the storage for 2 months at 27°C. was very slight. Though the dispersion of vitamin A in “Miso” was not uniform at the early period of fermentation, the uniformity became high in the products owing to the tank-change process repeated several times during the fermentation and crushing. On the other hand, the direct addition of vitamin oil onto nonfortified “Miso” was carried out easily by the use of a suitable mixer, and the high uniformity of vitamin A dispersion was obtained in spite of the simple addition. The loss of vitamin A in this “Miso” was 2-3%, after 2 months storage.
