Determination of organic acids and some preservatives in wine and spirits
The organic acids profile in wine is a highly informative parameter since it reveals important features of the whole technological process. It is also one of the most important criteria for wine authentication. In spirits like cognac, brandy or whiskey, the presence of certain organic acids can indicate the violation of distillation or maturation processes or reveal the tendency to precipitate during storage. Some organic acids (sorbic, benzoic, ascorbic) can serve as preservatives; their presence is strictly ...

Determination of D- and L-isomers of tartaric and malic acids in wines, wine materials, and food additive
Naturally occurred is predominantly L-form of tartaric acid whereas its D-form and the relevant racemic mixture can be artificially synthesized. Generally, artificial acidification of wine with tartaric acid is allowed by OIV, but only pure L-form must be used for this purpose. Thus the analysis of tartaric acid isomers either in food additives or directly in wine can be an important parameter in clarifying any deviations in wine production. Analysis of isomers of malic acid is also within the necessary ...

Determination of vanillin, sinapic, coniferyl, and syringic aldehydes in brandies and brandy spirits
The presence or absence of aromatic aldehydes (vanillin, sinapic, coniferyl and syringic aldehydes) in a sample and also their weight content and proportion allows determination of authenticity and quality of brandies and brandy spirits, and revealing a counterfeit. Together with aromatic aldehydes, it is possible to determine phenolcarbolic acids, such as sinapic, syringic, ferulic, salicylic, cumaric, vanillic, ellagic, p-hydroxybenzoic, caffeic, gallic, protocatechuic. Identification and weight content of these ...

Agriculture sensors solutions for viticulture industry
For wine growers it isn't just a question of giving your vines enough water - sometimes they need to stress their grapes by depriving them of moisture to ensure that the fruit reaches the quality sought by the winemaker. In particular, soil moisture levels are critically important to the management of sugar and anthocyanin in the initial stages of ripening right the way through to the production of flavor compounds in the later stages of the lifecycle of the grape. ...
