產品貨號：ZZK-K-ETSULPH
產品品名：二氧化硫檢測試劑盒
英文品名：Total Sulphite (Enzymatic) Assay Kit
規格型號：50 assays (manual) / 500 assays (microplate) / 588 assays (auto-analyser)
A simple, highly specific and reliable, enzymatic method for themeasurement of total sulphite (as SO2) in wines, beverages, foodstuffsand other materials. Suitable for manual, auto-analyser and microplate formats.
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 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-ETSULPH) is suitable for the specific measurement of “Total
Sulphite” as SO2 in wines, beverages, foodstuffs and other materials.
KITS:
Kits suitable for performing 50 assays in manual format (or 588
assays in auto-analyser format or 500 assays in microplate format) are
