Water Treatment for Hydroponics Industry
'A technique of growing plants in nutrient solution”. Hydroponics literally means water-working or water-activation. It is a cultivation technique for growing plants in highly oxygenated, nutrient enriched water, rather than soil. The nutrient solution and its management are the cornerstone for a successful hydroponics system. The function of a hydroponics nutrient solution is to supply the plant roots with water, oxygen and essential mineral elements in soluble form. In soil, biological decomposition breaks ...

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 ...
