Sulphite Test Strips
Couldn't load pickup availability
This test allows a quick and easy method to determine the sulphite in solution. The ph of the liquid to test should be in the range of 8-10. Take a small sample of the liquid and ph adjust to the 8-10 range before testing for accurate results.
Sulphite is commonly used as an oxygen scavenger in process and boiler water. To avoid resulting in excessive levels of sulphite, the concentrations need to be controlled for which the Sulphite Indicator Strips can be used. These strips may also be used to control sulphite concentrations in food treated with sulphur compounds and in the process of winemaking.
This test will indicate the ranges of 10, 50, 100, 250 and 500 mg/L (ppm).
The term ‘sulfites’ is an inclusive term for sulfur dioxide (SO2). SO2 is a preservative and widely used in winemaking (and most food industries), because of its antioxidant and antibacterial properties. SO2 plays a very important role in preventing oxidization and maintaining a wine’s freshness. In fact, there are really very few wines that are made without some use of SO2 as wines without any SO2 generally have a shorter shelf life – about six months, and need to be kept in perfect storage conditions. Given that a winemaker has very little control over the wine’s storage conditions SO2 is so widely used to help guarantee that the bottle of wine you open will be fresh and clean, and taste as intended.
A target with a level of 50 mg/L at fruit crushing, or up to 100 mg/L if you suspect any problem, such as mouldy fruit is ideal. Any higher than this and the yeast will find it difficult to ferment.
In the EU the maximum levels of sulfur dioxide that a wine can contain are 210 ppm for white wine, 400 ppm for sweet wines and 160 ppm for red wine.
It may seem strange that Red wines typically contain fewer sulfites but they contain tannin, which is a stabilizing agent, and also almost all red wines go through malolactic fermentation. Therefore, less sulfur dioxide is needed to protect the wine during winemaking and maturation.
Any commercial wine containing more than 10 parts per million (ppm) of sulfur dioxide must state on the label ‘contains sulfites’.
