Study on the Migration Law of Formaldehyde and Melamine in Bamboo Fiber Tableware Under Acidic Conditions
Objective:To study the migration rule of formaldehyde and melamine in bamboo fiber tablewar.Method:According the expected use of bamboo fiber tablewar,different experimental conditions were selected to test the formaldehyde migration by acetylacetone spectrophotometr and melamine migration by high performance liquid chromatography.Result:Under acidic conditions,the migration of formaldehyde and melamine was significantly increased in high temperature;formaldehyde and melamine migration increased first then decreased with the increase of use times;the use of steel wire balls to clean the surface of bamboo tableware will accelerate the escape of melamine and formaldehyde.Conlusion:Higher temperature,more use time or wire scrubbing conditions would affect migration of formaldehyde and melamine,attention should be paid to the safety of bamboo fiber tablewar.
