Abstract:

A monolithic material sorptive extraction coupled with gas-chromatography-mass spectrometry method has been
established and applied to evaluate the volatile compounds of Jinhua ham. Orthogonal experimental design was used to
examine the effects of parameters including types of MonoTrapTM, sample amount, temperature and extraction time. The
optimal extraction parameters were determined as follows: 5.0 g of sample were subjected to extraction at 60 ℃ for 60 min
using MonoTrapTM RCC18. A total of thirty-one compounds, including hydrocarbons, aldehydes, ketones, alcohols, acids,
esters, sulfur compounds, nitrogen compounds and others, were identified in Jinhua ham using the proposed method.

Key words: Jinhua ham, volatile compounds, MonoTrap, gas chromatography-mass spectrometry (GC-MS)
