INTRODUCTION Sulfite is a widely used food preservative and whiten- ing agent that received GRAS (generally recognized as safe) status from 1959 until 1986. In 1986, the U.S. Food and Drug Administration (FDA) revoked GRAS status when adverse reactions in sulfite-sensitive individuals were reported. Since then, the FDA has required warning labels on any food containing more than 10 mg/kg of sulfite or beverage containing more than 10 mg/L. Six sulfiting agents are currently approved by the FDA for use as food additives: sulfur dioxide, sodium sulfite, sodium and potassium bisulfite, and sodium and potassium metabisulfite. 赛默飞戴安ICS-2100离子色谱系统
