1 Scope
This standard specifies the method for determination of food simulants 1,1,1-trimethylolpropane.
This standard applies to the four food simulants water, 3% (mass concentration) solution of acetic acid, 10% (volume fraction) ethanol solution and olive oil
Determination of the content of 1,1,1-tris propane.
Three of the standard water-based food simulants water, 3% (mass concentration) of acetic acid and 10% (volume fraction) ethanol methanol propionate 1,1,1-tris
The lower limit of detection of alkyl 0.60mg/L, olive oil mimetic 1,1,1-trimethylolpropane lower limit of detection was 0.60mg/kg.
