Yes, they are
No, sulfites do not contain iodine. Sulfites are a group of chemical compounds containing sulfur and oxygen often used as preservatives in foods and beverages, while iodine is a separate chemical element found in nature and used in some disinfectants and medications.
Sulfur is a chemical element found in nature, while sulfites are chemical compounds containing sulfur. Sulfur itself is not harmful to health, but sulfites can cause allergic reactions in some people, especially those with asthma. Sulfites are commonly used as preservatives in foods and can pose a risk to food safety if not properly regulated and labeled.
No, sulfa refers to a group of antibiotics containing sulfonamides, while sulfites are sulfur-based compounds used as preservatives in foods and beverages. They serve different purposes and have distinct chemical compositions.
sulfites
Sulfur or sulphur) is the element (S). Sulfites (also sulphites) are compounds that contain the sulfite ion (SO2−3)
No, sulfites are minerals and do not evaporate like alcohol. It's possible they may interact with other ingredients and change their chemical make up, but they don't go away.
Sulfites are compounds used as preservatives in wine and other foods, and they are quickly metabolized by the body. Generally, sulfites do not remain in the system for long; they are typically processed and excreted within a few hours. However, individual reactions to sulfites can vary, especially for those with sulfite sensitivities or asthma, which may lead to delayed symptoms. Overall, most people will not experience lingering effects beyond a day after consumption.
Sulfur can be found in various chemical compounds such as hydrogen sulfide (H2S), sulfuric acid (H2SO4), sulfates (e.g. gypsum, Epsom salt), sulfides (e.g. iron sulfide), and sulfites. It is also present in organic compounds like amino acids (e.g. cysteine, methionine) and vitamins (e.g. biotin, thiamine).
sulfites are mostly insoluble except for the Na, K, NH4 sulfites
some wines and balsamic vinegars naturally produce it during the fermentation process. However many are added, because sulfites are a form of sulfur, and sulfur is naturally an anti-bacterial, anti-fungal, which is perfect for preserving foods and wine.
