막걸리의 제조공정 중 2단사입시에 lysozyme 270ppm과 glycine 0.27%구 및 lysozyme 450ppm과 glycine 0.45% 구를 첨가하여 발효시킨 후, 주요를 2배 희석시켜 발호성분변화, pH 변화, acetic acid 함량, 핵산 관련물질의 함량, 관능검사 등을 측정하였다. 제조과정 중 lysozyme과 glycine의 첨가는 막걸리 발효에 어떠한 영향도 미치지 않았으며, lysozyme 혼합 처리구는 대조구에 비해 저장기간 동안 pH의 감소가 둔화되었고, 초산 생성량이 현저히 억제되었다. 또한 $3^{circ}C$에서 2주 저장한 막걸리의 핵산 관련물질은 대조구에 비해 IMP, inosine함량이 더 많았고 관능검사에서도 lysozyme 혼합 처리구가 맛과 기호성 면에서 그 유의성이 인정되었다.
Characteristics of brewing product, Mageoly mashes diluted by the same ratio of water was investigated for alcohol formation, pH change, acid formation nucleotide content and sensory evaluation stored at $3^{circ}C;or;30^{circ}C$ during 7 days. Each sample was mixed with lysozyme 270ppm and glycine 0.27%, or lysozyme 450ppm and glycine 0.45% on the secondary brewing process in Mageoly brewing. The brewing was not affected by addition of lysozyme and glycine mixture. When the lysozyme-glycine mixture was added during brewing, that resulted in a decrease in pH, a suppression of acid formation and an increase in IMP and inosine content Therefore ere was significantly improved in taste and palatability.
