  • Histamine is a biogenic amine, a chemical compound formed by the action of microorganisms on amino acids present in foods. High amounts of histamine in food can cause organoleptic alterations as well as trigger undesirable effects once consumed and, therefore, histamine concentrations should be controlled. Although it is true that there are currently no global regulations, acceptable limits for histamine concentrations in wines are around 10 ppm. Info + Purchase
  • IONS MULTICAL. 5 levels with 10 mL. Multiparameter calibrator with five synthetic matrix liquid levels that contain various metals at adequate concentrations to calibrate the measurement procedures. Info + Purchase
  • Metal components in wine can originate in grapes or the machinery used to make wine. A high iron content can cause clouding due to a lack of solubilization, thus affecting the color and clarity of the wines. Info + Purchase
  • L-lactic acid is the product of the metabolism of malic acid during the malolactic fermentation. L-lactic acid is perceived as less acidic and softer on the palate compared to malic acid. Info + Purchase
