適用范圍：This document, part of EN 13130, specifies an analytical procedure for the determination of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone in the food simulants water, 3 % w/v aqueous acetic acid, 15 %v/v aqueous ethanol and olive oil or approved substitute. The level of3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone determined, is expressed as milligrams of3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone per kilogram of food or food simulant. The method isapplicable to the quantitative determination of 3,3-bis(3-methyl-4-hydroxyphenyl)-2-indolinone in anapproximate analyte concentration range of 0,18 mg/kg to 4/ kg of food simulants.NOTE 1 The method should also be applicable to other aqueous food simulants as well as to the other fattyfood simulants e.g. a mixture of synthetic triglycerides or sunflower oil.NOTE 2 The suitability of the fat simulant should be assessed prior to setting up migration tests. Olive oil hasbeen found to give unacceptable interference in some cases.
