D - Lactic Acid, reagent kit for wine Colorimetric Enzymatic method for ascorbic acid

Enzymatic method for ascorbic acid determination

Cleavage of the disulfide bond (R-S-S-R) of DTNB by a sulfite molecule yields the 5-mercaptan- 2-nitrobenzoate molecule

expressed as g/L of tartaric acid

Color is also an important indicator in many winemaking pro- cesses

Traditional methods of tannin determination require the preparation of specific reagent solutions and are demanding in time and preparation
