The purpose of this study was to closely examine the inhibitive effect of erythritol on growth and acidogenic ability of Streptococcus mutans. As expected, the growth of S. mutans was comparably increased with the addition of sucrose. However, xylitol and erythritol remarkably reduced the growth of S. mutans. Growth inhibition was detected at more than 5% of erythritol although xylitol showed growth inhibition effect at all concentrations tested. Growth inhibition effect was monitored with the combination of same concentration of erythritol and other carbohydrates. Combination of 5% or 10% erythritol with xylitol showed effective growth inhibition. Addition of 2.5%, 5%, or 10% erythritol with sorbitol also showed growth inhibition. From these results, erythritol showed potency of growth inhibition of S. mutans, which is involved in dental caries, and was confirmed to be an excellent sugar substitute, which has effect on preventing caries.

최근 대체 감미료로서 당알코올과 합성감미제에 관한 연구가 활발히 진행되고 있다. 에리스리톨은 포도당을 원료로 효모에 의해 생산되는 포도당 발효감미료로서 과실류, 버섯, 포도주, 청주, 간장등의 발효식품에 함유되어 있는 천연당질로 $C_4H_{10}O_4$의 분자구조를 가지는 4탄당의 당알코올이다. 구강내에서 산생성균인 Streptococcus mutans의 증식과 산생성, 치면세균막 형성 및 치아우식증 등은 여러 종류의 영양물질이 혼합되어 있는 구강내에서 일어나는 과정이므로 본 연구는 에리스리톨과 다른 감미제에서 S. mutans의 성장력과 산생성력을 분석하여 에리스리톨이 치아우식증의 예방에 관여하는 중요한 기전을 밝혀내어 치아우식예방을 위한 제품을 생산하거나 활용시 올바른 정보를 제공하고 개선방안을 마련하기 위한 기초자료를 제공하고자 시행하였다. 연구결과 에리스리톨은 우식활성균의 성장을 억제시키고 산생성능을 감소시켜 치아우식을 유발하지 않으며 우식예방효과가 있는 자당 대체 감미제로 우수한 것으로 확인이 되었다.
