1 Scope
This standard specifies the method for determination of food simulants 1-octene and tetrahydrofuran.
This standard applies to water, 3% (mass concentration) solution of acetic acid, 10% (volume fraction) ethanol and other water-based food simulants and olive oil
Determination of 1-octene and tetrahydrofuran content.
Determination of 1-octene and tetrahydrofuran in food simulants water-based low limits were 2.0mg/L and 7.0mg/L, 1-octene olive oil
And tetrahydrofuran lower limit of detection was 2.0mg/kg and 7.0mg/kg.
