Abstract

Fermentation patterns of apple Gochujang mash prepared with different addition times of red pepper powder were investigated. Red pepper powder was added into Gochujang mash before and after fermentation of the mash. In the apple Gochujang mash without red pepper powder, viable yeast cell counts of Zygosaccharomyces rouxii Y-80 increased to 6.5 log CFU/g shortly after five days of fermentation, and ethanol concentration reached its maximum value (3.8% of the total volume) after 15 days of fermentation. On the other hand, in apple Gochujang mash prepared by the initial addition of red pepper powder before fermentation, viable yeast cell counts increased to 7 log CFU/g after 20 days of fermentation, and ethanol concentration reached 1.3% after 25 days of fermentation. Yeast growth and ethanol production were stimulated in the Gochujang mash without red pepper powder. Sensory evaluation scores were similar in the apple Gochujang regardless of addition time of red pepper powder.

고춧가루 첨가 시기에 따른 사과고추장혼합물에서의 에탄올 생성과 고추장 제조 후 관능검사를 실시하여 사과고추장의 가능성을 검토하고자 하였다. 고춧가루 첨가 전의 사과고추장혼합물에서 효모의 생육은 발효 5일 후 약 6.5 log CFU/ g으로 빠른 증식을 보였으며, 에탄올 생성 농도는 발효 15일 후 3.8%에 도달하였다. 고춧가루를 미리 첨가한 사과고추장혼합물의 경우에 효모균주의 생육은 발효 20일 후 7 log CFU/g으로 증가하였고, 25일 발효 후에 에탄올 농도가 1.3 %에 이르러 고춧가루 첨가 방법에 따른 에탄올 생성 농도에서 큰 차이를 보였다. 그러나 고춧가루 첨가시기에 따른 사과고추장의 전체적인 기호성에서는 큰 차이를 보이지 않았다.
