The harm of sulfite to human body

Introduction: sulfite is used as an antioxidant in food, drink and medicine, and often appears in unclean atmosphere So, the harm of sulfite to human body? Come and have a look with you! Sulfite is actually a general description of sulfur dioxide (SO2) In fact, sulfite is produced by yeast metabolism during wine fermentation So, the harm of sulfite to human body? Let's introduce the small edition of Baibai safety net! It is understood that sulfite is a widely used food additive, which can be used as food bleaching agent and preservative, mainly to prevent food browning and prevent fruit from blackening However, the excessive use of sulfite will do harm to human body Some experiments show that one gram of sulfite in one day can not cause obvious harm Four to six grams of sulfite in one day can cause gastrointestinal disorders, acute diarrhea, chronic poisoning, headache, kidney disorders, red blood cell and hemoglobin reduction and other symptoms Sulfite is easy to form sulfur trioxide anion radical (SO3 -) through one electron oxidation after entering the body SO3 - can react with O2 to form superoxide anion radical O2 - Recent studies have shown that sulfite can damage chromosomes and DNA Sodium bisulfite and sodium bisulfite (1:3) biological test solution can induce the frequency of chromosomal aberrations (CA) in Chinese hamster lung fibroblasts (CHL) significantly increased, with a clear dose-response relationship At low concentration, chromatid aberration is mainly induced At high concentration, both chromatid aberration and chromatid aberration can be induced It was also found that the longer the cells were treated, the lower the minimum concentration needed to cause genetic damage When CHL cells were treated with it for 24 hours, CA increased significantly at 5 mmol / L, and at 1 mmol / L for 48 hours The above is a small series for you to introduce some of the harm of sulfite to human body, I hope to help you!
