| Abstract: | Fast Determination of 3-chloro-1,2-propandiol in soy sauce and hydrolyzed vegetable Protein was development.The sample were cleanup with CHROMABOND XTR diatomite SPE column,derived from HFBI and detected by GC-MS.Quantitate by deuterated isotope internal standard of isotope.Detected limit was 0.005 mg/kg,the additive recovery was 81.3%-96.2%,the coefficient of variation was 4.35%～6.62%. |
