Bamboo charcoal food is just a concept

Bamboo charcoal peanut, bamboo charcoal bread, bamboo charcoal cake In the past two years, the bamboo charcoal food with the function of "detoxification and beautification" has become a new favorite of many people Some online stores even sold out of stock once Does bamboo charcoal food really have detoxification function? Can the original bamboo charcoal for external use be added to the food? Is it safe to eat such food? At the same time, many people question the concept of bamboo charcoal Bamboo charcoal and bamboo charcoal powder, what's the effect of bamboo charcoal food? What is the raw material of bamboo charcoal powder? The data shows that bamboo charcoal is the charcoal made from bamboo, because it has many micropores, thus greatly increasing the surface area It is these microporous structures and huge surface area that make bamboo charcoal have good adsorption performance and play an important role in water purification, air purification and deodorization "Bamboo charcoal powder used to be a common Chinese medicine, which has the effect of beauty and detoxification, but now it is rarely used So far, there are few studies on nutrition that show that bamboo charcoal powder has nutritional value " Zheng Peifen, director of nutrition and digestive department of Zhejiang hospital, said When it comes to the detoxification function of human body, the waste in the body can be discharged from the body through three channels, namely, liver, intestine and skin As a doctor in digestive department, director Zheng doesn't suggest that you eat anything to defecate The best way to defecate is to defecate every day "Activated carbon is an antidote in emergency medicine, especially some oral poisons, which only enter the gastrointestinal tract and will not be quickly absorbed by the blood We will consider using activated carbon tablets to detoxify." Zhang Mao, director of the emergency department of the Second Affiliated Hospital of Zhejiang University Medical College, said For example, herbicide poisoning is more common Emergency doctors can use this tablet to detoxify Clinically, it has been verified that activated carbon tablet can detoxify, and activated carbon tablet can be smoothly discharged from the body, but it can not be inferred that bamboo charcoal powder can help detoxification, because there are differences between activated carbon tablet and bamboo charcoal powder, with different structure and dosage, the effect is different The standard of bamboo charcoal as an additive is questionable Recently, a popular science article by Dr Yun Wuxin, a doctor of food engineering, was published at the squirrel meeting of folk science popularization network science He thinks that bamboo charcoal food is a conceptual food that deceives people Cloud inadvertent analysis said that bamboo charcoal has not been approved for use as food processing aids, there will be no "food grade" quality standards Moreover, even if it is used as an additive in the process, it needs to be removed as much as possible in the finished product For those that can not be completely removed, the residue should be as low as possible, and can not have any function in the final product But now, the declared bamboo charcoal food not only didn't remove the bamboo charcoal at last, but also claimed to have various detoxification functions in the products Is cloud unintentional accurate? The reporter also consulted the food department of Zhejiang Quality and Technical Supervision Bureau yesterday For bamboo charcoal food, the Provincial Quality Supervision Bureau has given three replies First: according to the standard for the use of food additives (gb2760-2011), plant carbon black can be used as a colorant in six kinds of food, including frozen drinks (except for edible ice), pastries, biscuits, candy, rice products and wheat flour products Second: according to the food additive plant carbon black (gb28308-2012), using bamboo as raw material can produce food additive "plant carbon black" The enterprise shall obtain the production license of "plant carbon black" food additive, and the production products shall meet the requirements of relevant food safety standards Third: the enterprise shall obtain the food production license in accordance with the law to produce food, the purchased food additive "plant carbon black" shall meet the requirements, and the scope and amount of use shall meet the standards for the use of food additives (gb2760-2011) The reply from the Provincial Bureau of quality supervision shows that plant carbon black can be used as a food additive, and only as a colorant But is bamboo charcoal plant carbon black? If it really belongs to plant carbon black, can it be used like this? It is said that it can detoxify When the bamboo charcoal peanuts are sold out, input the words "bamboo charcoal peanuts" on the Internet and jump out of many online stores immediately The reporter also once bought this kind of bamboo peanuts through the network, and the shopkeeper claimed that these bamboo peanuts came from Taiwan Look carefully, the appearance of bamboo peanuts is not flattering at all It's black and tastes nothing special, just like the fish skin peanuts Yesterday, the reporter also contacted a wholesale manufacturer of bamboo charcoal peanuts, which operates Suichang local specialties and sells a bamboo charcoal peanuts produced by Suichang "The quality of bamboo charcoal peanuts is absolutely reliable," said Ms song, the owner of the store "They were sold out during the Spring Festival Healthy food, detoxification and beautification " But when the reporter asked if there was any evidence about the efficacy of detoxification, Ms Song said she wanted to find manufacturers Reporters later found that this bamboo peanuts mainly through e-commerce sales, there is no specific manufacturer In addition to the bamboo charcoal peanuts that once claimed to be sold out, some bakeries in Hangzhou once sold bamboo charcoal bread However, due to its ugly appearance and poor taste, it was gradually removed from the shelves In addition to bamboo peanuts and bread, there are all kinds of food, such as bamboo moon cake, bamboo coffee and so on These foods all claim to have detoxification function, which can absorb excess oil and regulate the stomach These bamboo charcoal foods are known to use bamboo charcoal powder Bamboo charcoal powder can also be purchased through the Internet, which is similar to flour Netizens also recommend many processing recipes Phenomenon Ministry of health: it is difficult to confirm whether bamboo charcoal is plant carbon black The reporter learned that on November 4, 2008, there was a letter from the general office of the Ministry of health on whether bamboo charcoal could be used as food raw materials or additives on the official website of the Ministry of health, which was in response to the general office of the General Administration of quality supervision at that time The letter mentioned that "bamboo charcoal was not included in the hygienic standard for the use of food additives" (GB2760) It is difficult to determine whether the bamboo charcoal belongs to common food raw materials or whether the raw materials are plant carbon black or plant activated carbon due to the lack of detailed information such as production process, quality specifications, etc Plant activated carbon can be used as processing aid for food industry, but it should be removed before the final product is made " More than four years later, there is no final conclusion on the relationship between the two, and experts in different fields have different opinions Professor Ying Tiejin, a professor in the food department of Zhejiang University, said they could not draw an equal sign directly "Bamboo charcoal and plant carbon black are two concepts They can't be equated, so bamboo charcoal can't be added to food I think a lot of bamboo charcoal food is another kind of blind worship Professor Ying thinks that a series of processing processes are needed from bamboo charcoal to plant carbon black One of the essential links is high temperature, which is likely to produce some carcinogens "The function of food is very serious, which needs a lot of data research to support It can't be inferred that activated carbon has the function of detoxification after it becomes food because it has the function of adsorption." Professor Ying said Professor Zhang Wenbiao, vice president of Engineering College of Zhejiang agricultural and Forestry University, is the first doctor who studies bamboo charcoal in China For bamboo charcoal food, he said: "from the perspective of source, bamboo charcoal powder can also belong to plant carbon black, which can be called food additive However, not all bamboo charcoal powder can be called plant carbon black It must be produced in strict accordance with national standards, from material selection to processing technology, all of which meet the standards In terms of use, I think the pace of progress will slow down There is a lot of room for the development of the function of bamboo charcoal Countries such as Europe and the United States are also developing some bamboo charcoal food In the development of bamboo charcoal food in China, we should be careful Whether we can directly add it and how to add it should be well studied " "Plant carbon black is a colorant in food additives The function of colorant is to color food Different foods have different processes and ways of adding them." Huang Xiantang, President of Zhejiang food additive industry association, said that for example, beverage colorant can be added directly, pastry colorant can be mixed with flour, and the usage is different However, as an additive of colorant, if you want to claim that it has special functions, such as plant carbon black, which claims to have the function of detoxification and beautification, you must have a large number of research data support This kind of research can be done by the enterprise itself, but these studies must be recognized by the official expert group before they can claim the function Interpretation of traditional Chinese medicine: healthy people do not need detoxification Although there are many opinions about the attribution of bamboo charcoal powder in the industry at present, and there is no clear definition in the country, but for detoxification, experts have said that they should study carefully, and can not infer that the bamboo charcoal powder in food form has detoxification function because it has the function of absorbing heavy metals This also involves the theory of toxins in the body Ma Hongzhen, director of Nephrology Department of Zhejiang hospital of traditional Chinese medicine, said that the concept of "poison" in traditional Chinese medicine has been misunderstood and become a gimmick for the sale of many products "Healthy people are not poisonous Only when they are sick, they are considered poisonous by traditional Chinese medicine, such as heat poison and damp poison At this time, they need detoxification At this time, detoxification should be under the guidance of doctors, rather than simply eating some food to detoxify " Director Ma said that as a doctor of Nephrology, he has received many young people He just ate some so-called detoxification and beauty care products at random and had kidney problems Instead of detoxification, these so-called detoxification became poison taking "The human body needs to be detoxified if there is any In a healthy state, the human body will produce some metabolites, which will be discharged from the body through the kidney, gastrointestinal tract, skin and other channels, without special food to help metabolism " Director Ma said In the past two years, it was very popular to eat mungbean The myth of mungbean was mentioned in the folk that mungbean has the effect of clearing away heat and detoxification In fact, this is the misreading of "poison" in traditional Chinese medicine "In ancient times, due to the limitation of medical technology, mung bean would be used to assist in emesis and detoxification after poisoning, so the efficacy of mung bean detoxification came However, with the development of medical technology, mung bean is no longer used in medicine to detoxify Mungbean is just a cool food that can help to get rid of the fire Director Ma said that because of the lack of understanding of the theoretical system of traditional Chinese medicine, some people have evolved the view that there is "poison" in healthy human body.
