The interaction of tannins from different sources (grape skin, grape seed and wine) with bovine serum albumin (BSA) was studied using a continuous flow method with nephelometric detection. The tannin samples were mixed in a reaction chamber with increasing BSA concentration and the resulting tannin-BSA insoluble aggregates passed through a flow cell where the turbidity was monitored. Based on this...
The disrupting effect of three different ionic carbohydrates (xanthan, pectin and gum arabic) on the formation of tannin-protein insoluble aggregates was assessed by nephelometry using bovine serum albumin (BSA) and several procyanidin fractions previously extracted from grape seeds. The presence in solution of any of the carbohydrates studied was found to restrain the formation of insoluble protein-tannin...
