Chitosan in sparkling wine production: innovation in clarification and microbial control
Fungal chitosan is a wine additive used to eliminate undesirable molecules (copper, ochratoxin) or micro-organisms that affect wine quality. We will begin by reviewing the regulations governing its use and the recommendations of the oenological codex. We will then examine its mode of action and effectiveness, taking into account the many micro-organisms encountered throughout the winemaking process. Finally, we will look at the effects of chitosan treatment on the sensory qualities of wines.
