Description of goods: potassium bicarbonate mol.formula: khco3 chemical properties: white crystals andstable in the air, easily soluble in water and the solution appears weak base, insoluble in ethanol. Physical property odorless white powder or crystals, mol.wt:100.11, specific gravity:2.17. Characteristics potassiumbicarbonate (e-501) is a product deacidifying which modifies the ph and lowersthe acidity. Added to wort or wine, it reacts with tartaric acid and producespotassium bitartrate which is insolubilized effectively. Applications duringthe harvest, as deacidifier of the must. Inwhite, ros and red wines, to correct acidity during the elaboration process. Organolepticqualities potassiumbicarbonate softens wines by giving greater harmony and balance while reducingtheir acidity. Does: mustor wine 0.2 - 1 g / lthe maximum deacidification allowed in wines is 0.65 g / l expressed as sulfuric acid (1 g / l expressed as acid tartaric), whichcorresponds to a treatment dose in potassium bicarbonate of 1.3 g / l. This product can be subject todeclaration.notes:1. Potassium bicarbonate reacts exclusively with tartaric acid formingbitartrate potassium. This delay precipitates when using the cold stabilizationprocess, which leads to a further decrease in total acidity.2. When applied before bottling, will wait 4 to 6 weeks before putting the winein bottle. manual dissolvebeforehand in a part of the must or wine at process, then add to the totalvolume. Shake vigorously after.
