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. In response to this statement, the State Administration of Food and Drug Administration recently through the official website to respond and interpret. Beijing Morning Post reporter also interviewed relevant experts, multi-angle exploration of the truth of this network gossip.
National Food and Drug Administration:
Sulphur fumigation roses to make tea is illegal
in response to the "market used to make tea dry roses, 80% of the sulfur smoked" statement, Beijing Morning Post reporters carried out a related search, found that the gossip began around 2015. Some of the posts said that rose tea made from sulphur fumigation roses is more colorful and sells well. From a cost point of view, fumigation roses are not easy to return to the tide, raw insects, can help businesses avoid wear and tear. And some fumigation rose tea is sold as "all-natural rose tea", through low-level high-selling, merchants from which to earn the difference, to obtain profits.
recently, the State Administration of Food and Drug Administration through the official website of the "rose tea 80% sulfur fumigation" response and risk interpretation.
the Introduction of the State Food and Drug Administration, roses are both a Chinese herbal medicine, recorded in the 2015 Chinese Pharmacopoeia, in which heavy-petal red roses are also allowed as food (mainly substitute tea) in China.
is a food additive allowed in China, mainly for food bleaching, anti-corrosion effect. China's National Standard Food Additives Use Standard GB2760-2014 stipulates that sulfur is allowed for fumigation of dried fruits, honeyed cold fruits, dried vegetables, clean surface treatment of fresh edible bacteria and algae, sugar, magic taro powder and other food categories.
fumigated food, allowing certain sulfur dioxide residues, with maximum residues from 100 mg/kg to 900 mg/kg.
roses are classified as tea products in the GB2760 food classification system and are not included in the category of foods allowed to be fumigated with sulfur. Therefore, the use of sulfur fumigation of roses is illegal use of food additives.
Rose as a medicinal herbs and food
there are corresponding standards for its sulfur dioxide limit
although roses as food in the processing process is not allowed to add sulfur dioxide, but China's relevant regulations as a food or medicine rose sulfur dioxide content limit.
this, the National Food and Drug Administration's explanation is that sulfur itself is one of the elements of nature, roses as a food may also have a certain source of sulfur dioxide from their own or the environment. Therefore, even if sulfur dioxide residues are detected in rose tea, it cannot be fully determined that sulfur fumigation or artificial addition of sulfur dioxide requires the use of food additives in combination with the supervision of the specific production process.
it is understood that the 2010 Supplement to the Pharmacopoeia of the People's Republic of China stipulates that, in addition to 11 kinds of Chinese herbal medicines (yams, cow knees, powders, winters, hemp, gansui,pox powder, white and, white, white art) If the process must be fumigated with sulfur dioxide, the residual amount shall not exceed 400 mg/kg, and the residual amount of sulfur dioxide shall not exceed 150 mg/kg for other Chinese herbal medicines and drink tablets that have not been fumigated but take into account the existence of the background.
the United Nations Food and Agriculture Organization/World Health Organization also stipulates that "sulfur dioxide residues in herbs and spices shall not exceed 150 mg/kg".
roses, if used as medicinal herbs, should meet the 150mg/kg limit.
Rose as a food although sulfur fumigation is not allowed in the processing process, but due to the existence of sulfur dioxide into the background factors, according to the "People's Republic of China supply and marketing cooperation industry standard substitute tea" GH/T1091-2014 standard, rose as substitute tea, its sulfur dioxide content should not exceed 100 mg/kg.
It is worth noting, however, that GH/T 1091-2014 is an industry standard, not a national standard, which means that there is currently no uniform national standard for roses as substitute tea to limit sulfur dioxide content.
of sulfur dioxide depends on intake
sulfur dioxide residues in rose tea are unavoidable, does that mean you can't drink any more in the future?
In this regard, the State Food and Drug Administration on the rose tea sulfur dioxide residue risk analysis, said that food, whether sulfur or sulphate as a food additive, will eventually be in the form of residual sulfur dioxide in food, the human body through the consumption of food containing residual sulfur dioxide and intake of sulfur dioxide. Sulfur dioxide enters the body to produce sulphates, and by the sulphate oxidase in tissue cells to oxidize it into sulfates, through normal detoxification and finally excreted by urine, so a small amount of sulfur dioxide into the body can be considered safe and harmless.
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 of sulphur dioxide (ADI) was 0.7mg/kg bw.
for example, adults weighing about 60 kg should be safe to consume foods containing sulfur dioxide residues every day of their lives, as long as they do not consume more than 42 mg of sulfur dioxide per day.
excessive intake of sulfur dioxide can damage the digestive tract and respiratory tract, damage the mucous membranes of organs, and produce gastrointestinal symptoms such as nausea and vomiting. Long-term excessive intake of sulfur dioxide will cause chronic poisoning, destroy the vitality of enzymes in the body, affecting the absorption of calcium.
The National Food and Drug Administration reminded that from the production point of view, the use of sulfur fumigated roses, will cause color bleaching and shallow, and sulfur dioxide smell, later also to remove flavor, fragrance. The cost of counterfeiting will increase a lot. However, if there is evidence that roses are indeed smoked with sulfur, they should be treated as a violation of the use of food additives. At the same time, consumers should not over-pursue the appearance of the product characteristics, should be rational purchase of food.
the expansion
is it reliable to recognize fumigation rose tea in this way?
For how to avoid buying sulfur fumigation rose tea, some netizens give seemingly "practical" advice, from the appearance, taste, smell, etc. to distinguish between natural and fumigation roses, then these methods are really reliable?
Interviewed experts: Science and Nutrition Information Exchange Center Business Department Director Yan Guangfeng
net transmission identification method 1: If rose tea drink tongue has a stimulating, spicy or odor, need to be carefully purchased, may have been smoked with sulfur.
Guangfeng: Do not rule out that some enterprises in the actual production process in order to good preservation, prevention of insects and other reasons, the use of sulfur dioxide for treatment, which is illegal, should be seriously dealt with. But this method of resolution may not be very reliable, and it is not very practical. People's five officials can usually only judge some over-fumigation products, and many other reasons may also lead to rose tea odor, can not confirm that it must be sulfur dioxide.
net identification method 2: no sulfur smoked rose tea, smelled of natural rose fragrance, and the flower fragrance is strong, with sulfur smoked flower fragrance is very light, and with some sour or pungent taste.

network identification method 3: no sulfur smoked generally purple-red, a little purple-black, with sulfur-smoked purple-black has faded, rose tea looks bright and bright, sell better.
: Roses themselves come in all kinds of colors.
net transmission identification method 4: sulfur-containing rose tea is generally high temperature drying, especially easy to break, falling down is very small pieces. Sulfur-free is not easy to break, falling off is also a relatively large fragment.
: is it easy to break mainly and petal peeling process and petal size itself. Some of the craft is better, the petals are not broken. Some of the petals may have been broken during processing.
