RESUMEN

Stone-fruit liqueurs contain high contents of the carcinogen ethyl carbamate (EC). In this study, we investigated the effect of plum fruit extract and single antioxidants present in plum fruit extracts on the reduction in the EC content during the macerating process in a plum liqueur model system and authentic plum liqueur. 30% ethanol model plum liqueur treated with 0.2% plum extract showed the lowest EC content with 55% reduction rate after the macerating process compared to the content in the control. Interestingly, neither 0.1% ascorbic acid nor 0.1% p-coumaric acid lowered the EC contents in the model liqueur, while they decreased the EC contents in authentic plum liqueur. This was possibly attributed to the synergistic effect of the plum fruit phenolics with the ascorbic acid and p-coumaric acid antioxidants. Thus, plum extracts can be applied to plum liqueurs to reduce the rate of EC formation.

RESUMEN

Ethyl carbamate (EC), a potential human dietary carcinogen, is found in fermented foods including the fermented soybean-based condiments, the major part of the Korean diet. Therefore, it is expected that their EC contents might pose health risks. Herein, we collected 111 condiments and estimated their EC contents via gas chromatography-mass spectrometry. Further, dietary intake of EC was evaluated, and the risk levels were assessed via the margin of exposure (MOE) approach and excess cancer risk assessment. EC contents of the condiments ranged from not detectable to 39.47 µg/kg, and the daily EC exposure ranged from 1.4 to 2.0 ng/kg BW per day, depending on gender and age groups in Korea. Of the condiments, soy sauce was the largest contributor to EC exposure. MOE and excess cancer risks for the average consumer were 166,300 and 9.0 × 10-8, respectively, and those for the consumers in the 95th percentiles (P95) were 53,504 and 2.8 × 10-7, respectively, indicating that the risk of exposure to EC is of lower concern in average consumers than heavy consumers. However, the EC exposure from condiments was higher than that in other Asian countries.Abbreviations: EC: ethyl carbamate; GC-MS: gas chromatography-mass spectrometry; MOE: margin of exposure; MRL: maximum residue level; IDL: instrumental detection level; IQL: instrumental quantification level; MDL: method detection level; MQL: method quantification level; EDI: estimated daily intakes; BMDL10: benchmark dose lower confidence limit.
