The current combined safe level for seven sulfites
used as additives in wine and other foods is sufficiently protective for consumers.
In some foods and beverages, such as wine, sulfites
occur naturally from fermentation.
com)-- Bioo Scientific's MaxSignal[R] Sulfite
Assay Kit, optimized for the screening of the sulfite
preservative highly prevalent in food and beverage samples, is a convenient and robust system for the detection of total sulfites
in multiple sample types.
Sulfur dioxide itself is a gas that readily dissolves in water, once dissolved it reacts with the water to form new compounds called sulfites
as shown in the following reaction:
For people with sulfur sensitivities or asthma, sulfites
can be problematic (if you want to avoid sulfites
, try organic brands).
are a group of sulfur-based compounds that occur naturally in many foods and may be added to some foods and pharmaceuticals as a preservative.
Must be made from organic grapes, but can include added sulfites
(used as preservatives).
Sensitive individuals can experience such adverse reactions when they consume sulfites
, with asthmatics being particularly vulnerable to such toxicity.
and MSG (monosodium glutamate) can contribute to asthma attacks.
While trace amounts of sulfites
occur naturally in wines during the fermentation process, most producers add more, later in the winemaking process, to prolong shelf life.
Wine labels also may have the terms "sulfite
-free," "no sulfites
added" or just "NSA.
are preservative used to increase the shelf life of wine and other foods.
