On the Content of Manganese in “Sake”

Abstract

The manganese content in 42 samples of “Sake” produced in various districts was determined by square-wave polarography.
Results obtained were as follows:
1. The content of manganese:
0.11-1.42ppm for “Sake” (mean value of 42 samples: 0.79ppm)
0.20-1.00ppm for polished rice (mean value of 10 samples: 0.53ppm)
2. It was found that the manganese content in the samples had no remarkable effect on the developed color of “Sake” after storage.
