The wine industry has been and remains a source of natural- tartaric acid. The tartaric acid can be obtained from such wastes as grape marcs, yeast, vinasse and wine stone. But the use of these wastes was limited in the Republic of Moldova by the production of tartaric acid lime (calcium tartrate) and wine stone, which were shipped to Ukraine and Armenia where the finished product is obtained. Currently, tartaric acid is used in considerable quantities in the winemaking and food industry, being a quite expensive imported product.

Remarkable enhancement of reactivity by tartaric acid (Brønsted acid) was observed in these reactions in the presence of anhydrous zinc nitrate (Lewis acid), due to coordination of the tartaric acid ligand to zinc ions increasing the acidity of the system.

Tartaric acid (AT) is an organic acid found in grapes and wines and known as a good preventive anti-oxidant and a metal chelation agent, used to ameliorate the quality of grape products. To prevent the oxidation of the coloring and organoleptic fractions of musts, juices and wines, ascorbic acid (AA) is also used in oenology. However, less information is provided about the synergistic influence of AT on the free radical scavenging activity of common antioxidants like AA. In this study, the contribution of different concentrations of tartaric acid on the antioxidant activity of ascorbic acid (A

Spectroscopy of UV-VIS-NIR combined with chemometric analyses was used as a non-destructive technique to build models for the quantitative characterisation of the main compounds of wine. The work in mixtures can give insight into how interferences affect the performance of calibrations in wines. Ethanol, glycerol, glucose, tartaric acid, malic acid, lactic acid, and acetic acid were evaluated as pure compounds and in mixtures. Different pre-treatments for the spectra and modelling strategies such as partial least squares (PLS) regression or Principal Component Regression (PCR) were evaluated.

The extraction of L(+) tartaric acid from aqueous solutions by amberlite LA-2 is a secondary amine mixture in different diluent solvents. Extraction equilibria of L(+) tartaric acid by amberlite LA-2 in 1-octanol, cyclohexane, isooctane, hexane, methyl isobutyl ketone (MIBK) solvents at temperature 298.15 K have been measured. The batch extraction experiments distribution coefficients (D), loading factors (Z) and extraction efficiency (E) were calculated. The maximum removal of L(+) tartaric acid is 91 % with MIBK and 0.92 mol.L-1initial concentration of Amberlite LA-2.

The solution structure and thermal stability of human prostatic acid phosphatase (hPAP) in the absence and in the presence of tartaric acid were studied by Fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). The temperature dependence of the infrared spectrum and DSC scans indicate that hPAP undergoes thermal unfolding at a temperature between 49.5 and 52.5 degrees C. Binding of tartaric acid does not lead to major changes in the secondary structure of hPAP, however, hPAP with bound tartaric acid shows a significantly increased thermal stability. These r

Seven kinds of natural organic acids were added to moderate artiﬁcial contaminated soil to investigate the effects of natural organic acids on growth of maize seedlings and phytoextraction of copper and lead by maize. The results show that the effects of organic acids on plant growth are different in Cu and Pb contaminated soil. The natural organic acids can change the dry matter distribution of the shoot and the root, oxalic acid and tartaric acid can increase the root biomass in different degrees. Oxalic acid and tartaric acid can signiﬁcantly increase the concentrations and uptake of Cu and

The effects of pH, the P/M ratio (mass ratio of sodium polyacrylate to metal ions), tartaric acid, and sodium citrate on the complexation of Cu2+ and Ni2+ by sodium polyacrylate were investigated. The retention of Cu2+ and Ni2+ by PAAS in single metal solutions with a P/M ratio = 4 and pH = 5 differed by 45.36%. When the complexation system of PAAS with a single metal contained tartaric acid and sodium citrate, the retention of PAAS for Cu

The amount of titration acid in must is in the largest number of cases with in the range 5.0-8.0 g/dm3. Wines, as a rule, contain less acids than must, and according to Regulations, titratable acidity is in the range of 4.0-8.0 g/dm3 expressed in tartaric acid, because a part of tartaric acid is deposited in the form of salts (tartar or argol) during alcohol fermentation. For wines that contain less than 4 g/dm3 of titratable acids there arises a suspicion about their origin, that is, that during the preparation some illegal acts were done. Because of that, the aim of this paper is to determin
