Use of Ultra-High Pressure Homogenization processing in winemaking:Control of microbial populations in grape musts and effects in sensory quality
(Elsevier, 2018-10-06)
Ultra-High Pressure Homogenization (UHPH) is a fast and efficient technique that can sterilizefluid foods at lowtemperatures or even under cooling conditions. A white must (Vitis viniferaL.) was processed ...
Effect of kaolin silver complex on the control of populations of Brettanomyces and acetic acid bacteria in wine
(Springer Verlag, 2018-03-19)
In this work, the effects of kaolin silver complex
(KAgC) have been evaluated to replace the use of SO2 for
the control of spoilage microorganisms in the winemaking
process. The results showed that ...
Use of a flor yeast strain for the second fermentation of sparkling wines: Effect of endogenous CO2 over-pressure on the volatilome
(Elsevier, 2019-10-10)
Saccharomyces cerevisiae flor yeast is used for the first time in sparkling wine-making. Twenty-six oenological variables and fifty-three volatile metabolites are quantified in the middle (P = 3 bar) ...
Microanalytical flow system for the simultaneous determination of acetic acid and free sulfur dioxide in wines
(Elsevier, 2020-12-24)
Free sulfur dioxide and volatile acidity are parameters related to the quality of wines. Traditional methods for their determination are tedious, time consuming and require analysis in decentralized ...
Influence of two yeast strains in free, bioimmobilized or immobilized with alginate forms on the aromatic profile of long aged sparkling wines
(Elsevier, 2018-01-04)
Production of sparkling wines involve a second alcoholic fermentation and contact with yeast less over an extended period of time, which influences the aroma composition and sensory quality of the ...
