We investigated the effects of thiamine on sake production. Thiamine had similar effects on small-scale brewing tests at rice polishing ratios from 70% to 40%.
We carried out the tests at various stages of thiamine addition. It was clear that the effects were increased by thiamine addition in early phases. We were able to produce low alcohol sake with high fragrance. It was apparent that diacetyl was not generated in thiamine-added brewing tests.
In the thiamine-added tests to yeast cultivation, the results were similar in the case of moromi mash.
As with the brewing of sake yeast, the thiamine had similar effects on sake production with the use of wine yeast.
