Flow through coulometry is used for analysis of wine samples the determination some heavy metals, sulphites, acidity and ethanol content. Low concentrations metals sulphite contents are determined by making use stripping chronopotentiometry. For measurement acid content thin-layer coulometric titration used.

The redox potential of spleen tissue in aiao was measured, and changes were observed after the administration of radioprotective drugs with reducing properties (aminothiols, dimercaptans, hydrazine derivatives, glucose, sulphites). The redox potential can be regarded as an indicator of the level of the energy metabolism of a tissue. The depression of the energy metabolism could be correlated wi...

A 14 year old boy was referred by his GP after persisting requests by his mother for investigation of a food allergy as a possible cause for 6-year history of soiling. He was not conscious of his bowels being opened and this would happen several times a day. Paediatricians claimed a psychological reason, which the patient and his mother denied categorically. • Symptoms inconsistent with allergy...

BACKGROUND Sulphites are widely used as a preservative and antioxidant additives in the food and pharmaceutical industries. Many types of biological and toxicological effects of sulphites in multiple organs of mammals have been shown in previous studies. OBJECTIVE The aim of this study was to investigate the effects of sodium metabisulfite (SMB) on testicular function and morphometric values ...

The surface and output of organic agriculture is growing steadily in recent years, being generally seen as a healthier, safer more sustainable alternative to conventional agriculture. Comparisons between products are nonetheless scarce the literature, especially case wine. aim this study was compare sulphite content pesticide residues both soils wines under production. Fourteen samples vineyard...

Sulphur dioxide (SO2) is usually used in winemaking due to its effectiveness as an antimicrobial and antioxidant agent. However, there growing interest finding alternatives SO2 because of adverse effects on human health. Therefore, this work, a low-SO2-producing Saccharomyces cerevisiae strain was selected the AIR-MIXINGTM M.ITM (A.M.) system, capable determining high extraction polyphenols, pr...
