AACC andAOAC approved method. This kit now contains an improved α-amylase thatallows the amylase incubations to be performed at pH 5.0 (as well as pH 7.0). 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 aging 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 (FSO2) and Total SO2 (TSO2). 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 foods and 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-TSULPH) is suitable for the specific measurement of “Total Sulphite” in wines, beverages, foodstuffs and other materials. KITS: Kits suitable for performing 80 assays in manual format (or 800 assays in auto-analyser format) are available from Megazyme. The kits contain the full assay method plus: Bottle 1: (2x) Total Sulphite Reagent 1 (40 mL) Contains sodium azide (0.05 % w/v) as a preservative. Stable for > 18 months at room temperature. Bottle 2: (2x) Total Sulphite Reagent 2 (20 mL) Contains sodium azide (0.05 % w/v) as a preservative. Stable for > 18 months at room temperature. Bottle 3: Sulphite Standard Sodium Sulphite (5 g).
