INTRODUCTION:

Sulphur dioxide (SO2) is used widely as an additive in various forms, most  commonly as sulphites (or sulfites), in the wine, beverage and food industries  where it acts primarily as an antimicrobial and antioxidant preservative.During wine making, sulphites are used as an essential additive, usually  at post-malolactic fermentation, in the control of contamination by  Brettanomyces during ageing and to also protect the wine against  detrimental “oxidative and enzymatic browning”. SO2 is only active  as an antimicrobial and antioxidant preservative in the unbound  “free” form. Given that SO2 becomes “inactive” when it binds the  colour pigments of wine, and with legal restrictions on SO2 levels in  wine, it has become valuable to wine producers to measure both the  Free SO2 and Total SO2. In addition to this, due to the increased  awareness of the adverse effects of sulphites and the prevalence  of sulphite intolerance in some individuals, sulphite levels in foodsand drinks are strictly regulated by various governing bodies and  therefore there is a requirement for accurate determination of the  level of sulphites in foods, beverages and wines.

This kit (K-ETSULPH) is suitable for the specific measurement of “Total  Sulphite” as SO2 in wines, beverages, foodstuffs and other materials.
