Effectiveness of carboxymethyl cellulose (CMC) on tartaric stabilization of cava base wine

Abstract

Recent EU regulations allow the use of carboxymethylcellulose (CMC) as a stabilization agent in wine. We tested CMC in bases for sparkling wines, which must be stabilized before the second fermentation that raises alcohol concentration by 1,5%. Our results show that CMC was able to stabilize wine against potassium bitartrate precipitation even when alcohol concentration was increased. stability was controlled by the Boulton’s test and by analyzing conductivity at -2°C. However if the wine was not completely stable the addition of CMC caused the appearance of a filamentous precipitate.

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.

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.

Ultra high pressure liquid chromatography for stilbenes separation and their determination in Burgundy red wines

In this study for the first time, eight natural stilbenes (trans-resveratrol, trans-piceid, cis-piceid, trans-astringin, trans-piceatannol, (+)-trans-s-viniferin, pallidol and hopeaphenol) isolated and purified from Vitis vinifera, were simultaneously separated and analysed within 5 mn by ultra high pressure liquid chromatography coupled with photodiode array detection.

Interaction between commercial mannoproteins and phenolic compounds of two red wines from different Portuguese grape cultivars

The interaction between mannoproteins and wine phenolic compounds is a subject of great interest as some studies show the possible impact in color stability and an improvement in the sensory characteristics namely the reduction of red wine astringency.
