  • asthma
  • sulfites cause serious symptoms in about 5% of people with asthma. (healthychildren.org)

  • Because of this, 5 to 10 percent of people die following sulfite exposure if they also suffer from asthma. (reference.com)
  • symptoms
  • Current methods cannot detect sulfite concentrations below 10 parts per million (ppm) in food, although many experts believe that a sulfite-sensitive person may experience symptoms at even lower concentrations. (healthychildren.org)
  • fruit and vegetables
  • citation needed] In 1986, the Food and Drug Administration in the United States banned the addition of sulfites to all fresh fruit and vegetables that are eaten raw. (wikipedia.org)

  • protonation
  • Evidence from 17O NMR spectroscopic data suggests that protonation of the sulfite ion gives a mixture of isomers: Sulfites are used as a food preservative or enhancer. (wikipedia.org)
  • Most of the intermediates involved in delignification in sulfite pulping are resonance-stabilized carbocations formed either by protonation of carbon-carbon double bonds or acidic cleavage of ether bonds which connect many of the constituents of lignin. (wikipedia.org)
  • produces

  • spectroscopic
  • They are grouped as either assimilatory or dissimilatory sulfite reductases depending on their function, their spectroscopic properties, and their catalytic properties. (wikipedia.org)
  • lignin
  • R-O-R' + H+ → R+ + R'OH R+ + HSO3− → R-SO3H The sulfite process does not degrade lignin to the same extent that the kraft process does and the lignosulfonates from the sulfite process are useful byproducts. (wikipedia.org)
  • foods
  • Sulfites are substances that naturally occur in some foods and the human body. (wikipedia.org)
  • however, many companies voluntarily label sulfite-containing foods. (wikipedia.org)
  • Regarding sulfites: While it is possible that sulfites can cause nasal flushing, itching, nasal congestion and even wheezing, there are other foods such as shrimp, prepared potatoes, sauerkraut, dried fruit, various prepared dips, beer and other beverages which contain greater concentration of sulfites than wine.
