Chip electrophoresis as a novel approach to measure the polyphenols reactivity toward human saliva.Saliva is a biological fluid with a multifunctional role that makes it interesting in terms of research and diagnostic possibilities.  In this work, chip electrophoresis was used alternatively to SDS-PAGE and results were compared.  Chip electrophoresis provides a very good reproducibility for wine and grape astringency.

A method based on SDS-PAGE analysis of saliva before and after the binding reaction with wine polyphenols has been successfully used in previous studies for measuring wine astringency by means of the saliva precipitation index.  In this work, chip electrophoresis was used alternatively to SDS-PAGE and results were compared.  Moreover, this approach is much faster than the conventional SDS-PAGE method requiring several hours for an analysis.
