elamine resin is widely used as kitchenware. It is formed by condensation reaction of melamine and formaldehyde. It is
required to manage for safety, because unreacted formaldehyde in melamine resin migrates into food. Accordingly, this
study was to investigate the migration of formaldehyde in four simulants(Water, 4% acetic acid, 20% ethanol, n-heptane). A total
of 200 samples were purchased from local market in Korea. The levels of formaldehyde in simulants were analyzed quantitatively
and qualitatively by HPLC(UV). Method validation was performed by determining linearity, limit of quantification(LOQ) and
recovery. The method presented good linearity over the range assayed 74.6-1865 ug/L and the LOQ ranged from 0.11 to 4.93
ug/L, respectively. Recovery was above 95% for four simulants. As a result of monitoring, formaldehyde is within the Korea
Food and Administration standard(4.0 mg/L) in four simulants. Among the four simulants, the migration into 4% acetic acid
was the highest and most of the migration into n-heptane was not detected. According to this study, it could be conclude that
formaldehyde level of melamine resin was safe to use for kitchenware.
