Abstract

The desmutagenic effects of ${\alpha}$-hydroxycarbonyl compounds, such as glyceraldehyde, glycolaldehyde, dihydroxyacetone, furfural, 5-hydroxymethylfurfural, maltol, acetol and acetoin and ${\alpha}$-dicarbonyls, such as diacetyl, glyoxal, methyl glyoxal and 2, 3-pentanedione were investigated against the mutagenic heterocyclic amines, such as Trp-P-1, Trp-P-2, Glu-P-1, Glu-P-2 and IQ. Most of the carbonyl compounds suppressed the mutagenicity of heterocyclic amines for S. typhimurium TA98, ${\alpha}$-dicarbonyl compounds showing a higher desmutagenic effect than ${\alpha}$-hydroxycarbonyl compounds. Among the ${\alpha}$-hydroxycarbonyl compounds, glyceraldehyde, glycolaldehyde and dihy-droxyacetone showed more effective desmutagenicity, and diacetyl among the ${\alpha}$-dicabonyl compounds had the highest desmutagenic effect. These carbonyl compounds alone also showed mutagenicity to S. typhimurium TA100 without S-9 mix. The reaction of carbonyl compounds with mutagenic heterocyclic amines also eliminated the mutagenicity of the former for S. typhimurium TA100.

식품의 안전성 평가를 위한 기초자료를 얻기 위하여, 식품의 가공, 저장 및 조리중에 식품성분간의 상호반응인 Maillard 반응을 이용하여 당의 분해로 생성되는 각종 카르보닐화합물을 강력한 돌연변이원성물질로 알려진 Trp-P-1, Trp-P-2, Glu-P-1, Glu-P-2 및 IQ에 각각 작용시켜서 이들 물질의 돌연변이성 억제효과를 연구 검토하였다. 그 결과, 카르보닐화합물에 의하여 돌연변이원성물질의 돌연변이원 활성이 크게 억제되었다. 사용한 카르보닐화합물중 ${\alpha}$-hydroxycarbonyl 화합물의 경우, glyceraldehyde, glycolaldehyde 및 dihydroxyacetone에서 돌연변이원성 억제효과가 크게 나타났다. ${\alpha}$-dicarbonyl 화합물의 경우, diacetyl에서 그 억제효과가 우수한 것으로 나타서, 전반적으로 ${\alpha}$-dicarbonyl 화합물이 ${\alpha}$-hydroxycarbonyl 화합물보다 돌연변이성 억제효과가 높게 나타났다. 한편, 공시한 카르보닐화합물 단독으로는 돌연변이 성을 나타내었으나, Trp-P-1등의 돌연변이원성물질과의 상호반응로 이들 두 물질의 돌연변이성이 동시에 소실되는 것이 입증되었다.
