Principle 3
Liquid food simulants 3,3-bis (3-methyl-4-hydroxyphenyl) -2-indolinone levels measured by reverse phase high performance liquid chromatography is adopted
UV detector at 235nm completion.
Before conducting fatty mimetic HPLC analysis, it has to be extracted with 80% aqueous acetonitrile.
By known 3,3-bis (3-methyl-4-hydroxyphenyl) -2-food simulant indolinone content samples for calibration to obtain quantitative and Inverse
Phase high performance liquid chromatographic columns with different polarities confirmed by UV detector at 280nm under.
