초록
에리스리톨은 4탄당의 당알코올에 해당되며 포도당을 원료로 효모에 의해 생산되는 발효 감미료제로 버섯, 포도주, 과실류, 청주, 간장 등의 발효식품에 함유되어 있는 천연당이다. 에리스리톨과 다른 감미제에서 Streptococcus mutans (S. mutans) 의 glucosyl transferase (GTF)와 fructosyl transferase (FTF) 의 유전자 발현 양상을 확인하여 치아우식 예방을 위한 제품을생산하거나 활용 시 올바른 정보와 기초자료를 제공하고자 시행하였다. 연구결과 에리스리톨은 치아우식에 관여하는 S. mutans 의 생육을 억제하는 것으로 나타났으며 자당(설탕) 대체 감미제로서 우식예방 효과가 우수한 것으로 확인이 되었다. 특히 세포외다당류 합성에 관련된 gtf B, gtf C, gtf D, ftf 의 발현이 낮게나타나 세포외부에 다당류의 합성을 억제하여 치면세균막 형성과 치면에 세균의 부착률을 감소시킬 수 있을 것으로 생각된다. 따라서 Streptococci에 의한 우식기전에 에리스리톨이 효과적으로 항우식 감미제로서 사용될 수 있다고 생각된다.
Abstract
Erythritol is a sweetener produced by yeast from glucose and a natural sugar found in fermented foods such as mushrooms, wine, fruits, rice wine, and soy sauce. Correct information and basic data when producing or using products for preventing dental caries by checking the gene expression patterns of glucosyl transferase (GTF) and fructosyl transferase (FTF) of Streptococcus mutans in erythritol and other sweeteners it was implemented to provide. Erythritol inhibited the growth of Streptococcus mutans, which is involved in dental caries. When used as a sweetener to replace sucrose, erythritol had an excellent caries-preventative effect. In particular, erythritol reduced the expressions of gtfB, gtfC, gtfD, and FTF, which are related to the synthesis of extracellular polysaccharides, and thereby reduced the formation of dental plaque and the attachment rate of bacteria to tooth surfaces. The study shows erythritol has potential use as an anticariogenic sweetener that inhibits the mechanism underlying caries caused by Streptococci.
