Continuous Stabilization of Chardonnay with Ion-Exchage Resin: Influence on Protein and Phenolic Profile of Wine
Unstable proteins may react with polyphenols, forming haze and precipitation in white wines. Therefore, the adsorption of these wine proteins is an essential step in the production of white wines. The objective of this study was to determine the influence of adsorption of these proteins on the stabi...
