In some fruits, the loss of astringency has been attributed to the ins
olubilization of recombinated tannins, formed by reaction with acetald
ehyde. This route has been investigated by on-line coupling of liquid
chromatography with ion spray mass spectrometry (LC-ISP-MS). The resul
ts reported herein indicate that LC-ISP-MS can be successfully applied
to tannin polymers and is very helpful in their identification. It al
so allows direct monitoring of the progress of polymerisation reaction
s. The mechanism of the acetaldehyde-induced polymerisation of flavan-
3-ols has thus been demonstrated.
