Investigation of the Chemical -Mineralogical Composition of Bentonite of the Khaudag Deposit and Synthesis of Wine Fining Agents Based on Its

Fining is about removing unwanted material from wine while still in the cellar.It is part of the clarification and stabilisation process and involves adding a substance to the wine that will flush out certain elements that may cause a wine to look hazy or affect its aroma, colour or bitterness.Fining removes 'colloids', which are molecules that include tannins, phenolics and polysaccharides.The fining agent binds to the unwanted particles in the wine, which means they become sizeable enough to be filtered out.The chemical and mineralogical composition of the Khovdak bentonite clay for the production of sorbents was studied.Microscopic studies of samples of bentonite clays were carried out using an MBS-10 optical microscope in transmitted and polarized light with an installed digital camera with a magnification factor of up to 600 s.The study of the phase composition of samples of bentonite clays of the Khaudag deposit was carried out by X-ray analysis.
