"Make sure you don't get dyed or smoked with sulfur." The owner of one of the stalls told the reporter that her goods were purchased from Liangzhu wholesale market As for the upward channel, it is estimated that it is the place of origin The price of Chinese wolfberry in her family is very good They are all used to supply restaurants There are also snack shops and small wholesale shops in the following towns When asked why the color is more vivid, the landlady didn't say much, but said "it won't fade" "If you eat or give away, you'd better buy something a little better." The owner said that the price of medlar recommended by her is a little bigger, the color is darker, and the price per Jin is yuan "It's no secret that the price of dry goods includes the price of sulfur for medicinal materials." A long-term engaged in wholesale medicine boss revealed that the key is to see how you use, how much The boss, who asked not to be named, said that some farmers used the price of sulfur as soon as they picked the herbs to kill mites and preserve them easily There are also old medicinal materials, which can be used for renovation once the sulfur price is sprinkled Sulfur price fumigation is no secret in the traditional Chinese medicine industry, commonly known as "sulfonation" The way is very simple: just find a relatively closed place, place a shelf, put herbs on it, put a few lumps of sulfur price on the bottom, light the sulfur price, then seal it with some leather paper, and smoke it for one night There are also simpler ones Open the plastic (10765, - 215.00, - 1.96%) film containing the medicinal materials Just sprinkle a little sulfur price powder on it, seal the film and put it overnight In recent years, the excessive use of sulfur price fumigation has become a semi open secret in the industry The excessive price of sulfur is called "melamine" in the field of traditional Chinese medicine In fact, the technology of sulfur price fumigation has existed thousands of years ago, especially for some Chinese herbal medicines with large sugar content and water content In order to prevent insects and moths, after picking, the growers will fumigate with sulfur yellow, which is easy to preserve Song Xufeng, deputy director of Hangzhou Institute of drug control, said that the traditional technology has gradually changed in modern society Because of the difference in price, many illegal traders have turned to industrial sulfur price The first is to increase the weight of traditional Chinese medicine and gain more profits Another purpose is to dye the mouldy traditional Chinese medicine The price of Lycium barbarum is purchased in two seasons a year, and it will be harvested in autumn soon Hangzhou Huadong Herbal Medicine Co., Ltd will send a special person to Ningxia cooperation base to see the harvest and drying equipment "The price of sulfur fumigation is the price of Lycium barbarum Fresh goods will be processed as soon as they are purchased Farmers have to watch the weather and eat If the weather is bad, they have to fight with the price of sulfur " Yang Hongtao, director of the company's production quality factory, told reporters that this kind of retail operation is difficult to control "According to the current technical conditions, the price of sulfur is not a necessity." Song Xufeng said that the traditional sulfur price smoking has been completely replaced by sun drying and oven drying, but the cost will be higher In order to solve the problem of severe sulfur price fumigation of traditional Chinese medicine and sulfur dioxide residue in its decoction pieces on the market, from April 2009, Hangzhou food and drug administration took the lead in promoting the non sulfuration work of traditional Chinese medicine decoction pieces in the country, and specifically controlled the sulfur price fumigation of traditional Chinese medicine The key monitored varieties include 26 varieties, such as Zhejiang shellfish price mother, angelica price, Gastrodia price, yam, Lycium price son, etc East China Herbal Pieces is one of the pilot enterprises "The barrier of non vulcanization promotion is that it is difficult to control the production area, to invest in the early stage and to keep in the later stage." Song said Take the price of Lycium barbarum as an example An oven is often over 100000 yuan, which is hard for ordinary farmers to bear Later stage storage and storage conditions are also relatively harsh, such as the price of wolfberry without curing treatment like cool storage, room temperature is within 20 ℃, while the price of wolfberry before sulfur price smoking is within 30 ℃ For more than three years, there was no cure effect of Hangzhou traditional Chinese medicine In the first half of this year, 76 batches of Chinese herbal medicines (decoction pieces) were randomly inspected and entrusted for inspection by Hangzhou Institute of drug control, involving 25 varieties, and 7 batches of 7 varieties exceeded the national limit, with a total qualified rate of 90.8% "In general, the Chinese herbal medicines that consumers buy in drugstores and hospitals should be safe to eat." As for supermarkets, markets and the like, we can't guarantee them at present.
