Abstract
Thiamin in the various materials which used for Takja braving was determined and its quantitative changes in the Takju mashes which were mashed with polished rice and wheat flour respectively using Nuruk only for the enzyme source, and with wheat flour and corn powder respectively using Nuruk and Koji, were checked at 24 hours intervals during the whole brewing period. The results obtained were as follows. a) The thiamin contents in 100 grams of each materials were: Polished rice 107.8${\gamma}$ Wheat Pour 185.0${\gamma}$ Corn powder 410.2${\gamma}$ Nuruk 347.4${\gamma}$ Koji of wheat flour 170.1${\gamma}$ Koji of corn powder 257.3${\gamma}$ b) About 40 to 50 percent of thiamin in the polished rice, wheat flour and, corn powder were losed by steaming at 10 wounds for 50 minutes. c) The quantitative changes of thiamin in the Takju meshes showed a similar tendency. Thiamin contents were decreased markedly during 2 days after mashing but thereafter, almost unchanged till the mashes were ripened. Its decreasing rates in tile two plots uses Nuruk and Koji wereless thaw those in the two plots used Nuruk only. d) Approximately 6${\gamma}$ of thiamin was determined in 100 ml. of the ripened mash of the rice plot and 7.5${\gamma}$ in tire whet flour plot in the case of using Nuruk only. 12.4${\gamma}$ of thiamin was determined in 100 ml. of the ripened mash of the wheat flour plot and 15.4${\gamma}$in the corn powder plot in the case of using Nuruk and Koji. e) It was assumed that 2.4 to 3.5${\gamma}$ of thiamin were contained in 100 ml. of finished Takju of the two plots used Nuruk only and 5 to 7${\gamma}$ in the two plots used Nuruk and Koji. f) About 43.7${\gamma}$ of thiamin were determined in 100 grams of Takju cake of the rice plot and 56.1${\gamma}$ in the wheat flour plat used Nuruk only, and 81.4${\gamma}$ in the corn powder plot and 57.7${\gamma}$ in the wheat flour plot used Nuruk and Koji.
탁주 양조에 사용되는 각종원료중의 Thiamin과 쌀, 소맥분 및 옥수수분을 주원료로 일반 탁주양조법에 따라 담금하여 숙성시까지 술덧중의 Thiamin의 소장을 측정하여 다음과 같은 결과를 얻었다. 1. 각원료 100g중의 Thiamin 함량 $({\gamma})$은 쌀 107.8 소맥 분 185.0 옥수수분 410.2 누룩 347.4 소맥분입곡 170.1 옥수수분입곡 257.,3 이었으며 쌀, 소맥분 및 옥수수분중의 함량은 증자에 의하여 $40{\sim}50%$ 파괴됨을 보였다. 2. 쌀, 소맥분 및 옥수수분을 주원료로 하여 각각 담금한 술덧에서 Thiamin의 소장은 각 술덧에서 같은 경향을 보여 누룩단용법의 양구에서 담금 후 1, 2일 사이에 급격히 감소하며 이후 숙성시까지 큰 변동이 없었고 입곡혼용법의 양구에서는 담금초기에 누룩단용법구들에 비하여 감소율이 훨씬 적었다. 또한 각 숙성 술덧 100ml중의 함량은 누룩단용법의 쌀구에서 약 6${\gamma}$, 소맥분구에서 7.5${\gamma}$였고 입곡혼용법의 소맥분구에서 약 $12,4{\gamma}$, 옥수수분구에 서 15.4 ${\gamma}$ 였다. 3. 각숙성 술덧으로 제성한 탁주 100ml중에는 Thiamin이 누룩단용구들에서 $2.4{\sim}3.5{\gamma}$, 입곡혼용법구들에서 약 $5{\sim}7{\gamma}$ 함유됨을 알 수 있었다. 4. 각숙성 술덧의 지게미 100g중에는 Thiamin이 누룩단용법의 쌀구에서 약 $43.7{\gamma}$, 소맥분구에서 $56.1{\gamma}$ 그리고 입곡혼용법의 소맥분구에서 약 $57.5{\gamma}$. 옥수수분구에서 $81.4{\gamma}$ 함유되었다.
