Abstract

This study focuses on the impact of one Na-bentonite and one Ca-bentonite for the clarification of ‘Muscat blanc’ must before ‘prise de mousse’. The clays were used both individually and mixed together at amounts ranging from 10-100 g hL-1 as modelled by Central Composite Design. The heat-stability of colloidal matter, the concentration of total proteins and the content of the free- and glycosylated-terpenols of treated and control samples were assessed through O.I.V. methods, HS-SPME-GC-MS techniques, and UPLC-MS approaches.
