“…This is caused by changes of phase boundary properties between sample and matrix leading to a general reduction in solubility of hydrophobic compounds in the aqueous phase (Cheong et al, 2010;Yang & Peppard, 1994). Also important is the effect of sampling temperature on the extraction yield of headspace volatiles, since the vapor pressure generally increases with temperature, resulting in decreased partition coefficients for most compounds (Snow & Bullock, 2010). In order to define the most sensitive conditions, the effect of four inorganic salts (NaCl, MgSO 4 , CaCl 2 , (NH 4 ) 2 SO 4 ) on MeS-volatiles from 'Hort16A' fruit pulp was investigated at different extraction temperatures (20, 40, 60, 80°C) using HS-SPME.…”
