Experts analyze the risk of "sulfur fumigation of roses".

Original title: Expert analysis of "sulfur fumigation roses" risk
days ago, the State Food and Drug Administration organized experts on "sulfur fumigation roses" risk analysis. Experts point out that it is illegal to fumigate roses with sulfur, but a small amount of sulfur dioxide intake will not cause harm to the human body.
weChat group recently circulated "the market used to make tea of dried roses, 80% of the sulfur smoked." Reported that the sulfur fumigated roses, there will be part of the oxidation of sulfur dioxide attached to the roses, into the human body can form sulphate, long-term drinking of smoked roses will endanger health, there is a risk of cancer.
, experts point out that roses are a medicinal raw material. According to the relevant regulations, sulfur is allowed for fumigation of dried fruits, honeyed cold fruits, dried vegetables and other food categories. However, roses belong to the tea products category in the food classification system, and the act of fumigated roses with sulfur belongs to the illegal use of food additives. Whether the consumption of sulfur fumigation roses is harmful to humans depends on sulfur dioxide intake.
experts pointed out that if roses as medicinal herbs, sulfur dioxide residues should meet the limit of 150 mg/kg standards, if used as substitute tea, its sulfur dioxide content should not exceed 100 mg/kg industry regulations. Whether sulfur or sulphates are used as food additives in food, they are present in food in the form of residual sulfur dioxide, which is metabolized in the human body and converted into sulfates, which are eventually excreted by urine. The safety evaluation of JECFA (FAO/WHO Joint Committee of Experts on Food Additives), an internationally authoritative food additive risk assessment agency, found that the daily allowable intake (ADI) of sulphur dioxide was 0.7mg/kg bw. Therefore, in adults weighing about 60 kg, for example, it should be safe to consume no more than 42 mg of sulfur dioxide per day. Sulfur itself is one of the elements of nature, roses as food, allowing a certain amount of sulfur dioxide from their own or the environment residual background. (Reporter Chen Yanfei)
