Identification and quantification of c-glucosidic ellagitannins and their derivative in red wine aged in oak barrels

Abstract

The C-glycosidic ellagitannins constitute a subclass of hydrolyzable tannins of remarkable structural diversity. In this work we first achieved the hemisynthesis of flavano-ellagitannins, then we used them to develop a new efficient detection and quantification procedure for the C-glycosidic ellagitannins as well as flavano-ellagitannins. The presence in red wine aged in oak barrel of acutissimins A and B, of epiacutissimins A and B as well as of 1-O-ethylvescalagin was investigated. We were able to monitor for the first time the formation and accumulation of these compounds during wine ageing. The concentration of total ellagitannins first increased then decreased, the single compounds showing specific changes during ageing.

Investigation of the effect of gelatine and egg albumin fining and cross-flow microfiltration on the phenolic composition of Pinotage red wine

Results indicated that cross-flow microfiltration removed similarly to fining treatments the most astringent tannins, but cross-flow microfiltration also removed up to 14 % more colour. RP-HPLC and spectrophotometric results showed that egg albumin is a softer fining treatment compared to gelatine and cross-flow microfiltration.

Changes in wine secondary metabolites composition by the timing of inoculation with lactic acid bacteria: impact on wine aroma

For the first time, it was established that the timing of inoculation with LAB could significantly impact the concentration of many secondary metabolites leading to significant aromatic changes. From studied compounds, the most influenced were esters and diacetyl.
