Effects of Phenolic Evolution on Color Characteristics of Single-Cultivar Vitis vinifera L. Marselan and Merlot Wines during Vinification and Aging

Foods
The loss of red hue in dry red wine has been a persistent issue for wine enterprises in western China. We investigated the changes in anthocyanins and non-anthocyanin phenols during the industrial-scale fermentation and one-year bottle aging of Vitis ...

Malolactic Fermentation: Electrogenic Malate Uptake and Malate/Lactate Antiport Generate Metabolic Energy [PDF]

, 1991
The mechanism of metabolic energy production by malolactic fermentation in Lactococcus lactis has been investigated. In the presence of L-malate, a proton motive force composed of a membrane potential and pH gradient is generated which has about the same

La cytométrie appliquée aux mircoorganismes du vin

BIO Web of Conferences, 2017
Flow cytometry (FCM) is a powerful technique allowing detection and enumeration of microbial populations in food and during food process. Thanks to the fluorescent dyes used and specific probes, FCM provides information about cell physiological state and

An Amperometric Biosensor for the Determination of Lactic Acid During Malolactic Fermentation

Chemical Engineering Transactions, 2015
A lactate oxidase amperometric biosensor was developed and optimized for the malolactic fermentation monitoring during winemaking process. Lactate oxidase enzyme was immobilized on prussian blue modified screen-printed carbon electrode in order to reduce

Results Concerning the Evolution of Bacterial Population during the Malolactic Fermentation

, 2010
During this experiment, the evolution of inner lactic bacteria microflora was monitored, during a spontaneous and conducted malolactic fermentation developed in the fall of the year 2006 at red wines obtained in Minis – Maderat wine yard.

Evaluation of the settling of malolactic starters within the indigenous microflora of wines

OENO One, 1997
Six malolactic starters were experimented. The objective was an evaluation of the capacity of each one to settle in different wines. First we obtained the genomie DNA fingerprinting with Not I a rare cutting enzyme after pulse field gel electrophoresis ...

Monitoring malolactic fermentation using HPLC-UV-RI

, 2012
In the malolactic fermentation, which is the second wine fermentat ion, the malic acid is consumed by lactic acid bacteria to yield lactic acid, resulting in a reduction of the wine fixed acidity.

Ultrasonic velocity of water-ethanol-malic acid-lactic acid mixtures during the malolactic fermentation process [PDF]

, 2015
During malolactic fermentation in wines, malic acid is transformed into lactic acid by the action of lactic acid bacteria. This process can be monitored on-line by measuring the velocity of a low intensity ultrasonic wave propagating through the medium ...
