Determination of aliphatic aldehydes in maize and grass silages using on-fibre derivatisation with O-(2,3,4,5,6-pentafluoro)- benzylhydroxylamine

Original language description

Aldehydes and ketones are volatile compounds of silages which probably affect feed preference, palatability and intake. A sensitive and fast method was developed to determine aliphatic aldehydes in maize and grass silages. The method is based on the solid phase micro-extraction and on-fibre derivatisation of aldehydes with O-(2,3,4,5,6-pentafluoro)benzylhydroxylamine hydrochloride (PFBHA). The derivatisation agent was adsorbed onto divinylbenzene/ poly(dimethylsiloxane) 65_m fibre and then exposed to the aldehydes in the headspace of the silage samples. Aldehydes selectively react with PFBHA forming volatile oximes, which were desorbed in the injection port of a gas chromatograph and analysed by mass spectrometry. Using this method, eight aldehydes were detected in maize and grass silages being ethanal, propanal, butanal, 2-methylpropanal, pentanal, 3-methylbutanal, hexanal and heptanal, at levels ranging fromtens to 200 mg/kg fresh matter.
