## Abstract A method for the determination of total 3‐chloropropane‐1,2‐diol (3‐MCPD) in edible fats and oils was presented. 3‐MCPD was released from 3‐MCPD fatty acid esters by transesterification with NaOCH~3~/methanol. After derivatization with phenylboronic acid, 3‐MCPD was determined by GC‐MS.

## Abstract A new method for the parallel determination of bound 2,3‐epoxy‐1‐propanol (glycidol) and 2‐ and 3‐chloropropanediol (2‐ and 3‐MCPD) in oil matrices is presented. It is based on an improved alkaline catalysed release of MCPD and glycidol, followed by a transformation of glycidol to monob
