4hw.com.cn: black ice cream is very popular recently. People describe it as like pouring a whole bottle of ink into it. But recently, the United States said that black ice cream is prohibited, mainly containing harmful elements. So can we eat domestic black ice cream? Let's have a look!
Why is black ice cream banned abroad
Recently, black ice cream, which is very popular in China, was found to have a great food safety problem in the United States. It is still not suitable for human consumption.
The Department of health and mental health of New York City announced that it is prohibited to add activated carbon in food and drink, and required relevant businesses to throw away the activated carbon in stock, so as to put an end to the sales of online red food such as black ice cream, black latte, black cupcake, etc.
The New York City Department of health and Mental Health said in a statement that under the U.S. Food and drug administration, the use of activated carbon as a food additive or food colorant is prohibited.
Experts said that activated carbon will not only affect the absorption of nutrients, but also reduce the absorption of drugs, and also reduce gastrointestinal peristalsis, which is easy to cause nausea and constipation, so it is not recommended to eat foods containing activated carbon.
1. Activated carbon is a black powder made of bone charcoal, coconut shell, sawdust and coal. It can make food black and is widely used in ice cream, coffee, pizza and cocktails. Activated carbon began to be used as an antidote to absorb stomach toxins in hospitals decades ago. However, it can also absorb drugs, reduce the efficacy, and may cause constipation or even dehydration.
2. New York City's health regulations have long ruled against adding carbon to food, and health officials have urged restaurants and cafes to ban the use of activated carbon. New York's famous creative ice cream store 'Morgan Stern's most cow ice cream' launched a black ice cream named 'coconut ash', which quickly became popular on the Internet. Some food stores have launched black lattes, black cupcakes, under the banner of "healthy food", with different colors, they are popular with customers. As a result, some people called for a clear ban on activated carbon.
Can I still eat black ice cream
It is suggested not to eat it. Food safety is still very important. Although activated carbon is non-toxic, it is obviously harmful to people's health to make food additives.
This kind of black food is as popular in foreign countries, because it is so popular that many problems arise. New York City has banned the sale of carbon black ice cream and lattes, which have become popular all over the world, due to the constipation caused by the active ingredients and the reduced efficacy of the active ingredients.
1. For decades, hospitals have been using activated carbon to detoxify patients, including those who overdose drugs. The substance is an absorbent that draws toxins from the stomach, but it also absorbs drugs, including birth control pills. If the coconut ash ice cream in China also has activated carbon, does that mean it can't be eaten.
2. A media contact with the coconut ash ice cream manufacturer, the other side said that one of the raw materials used was that the food itself was qualified by the relevant departments. As for why activated carbon is mentioned in the manufacturer's publicity, the other side said, 'I'm not sure, but as far as I know, it's not added with plant activated carbon'. Plant carbon black is a kind of edible melanin, which is used for coloring. It has no effect of activated carbon. As long as the maximum usage is not more than 5g / kg, it is safe.
Introduction to activated carbon
The material is amorphous carbon obtained by processing. It has a large specific surface area and good adsorption capacity for inorganic or organic substances and colloidal particles in gas and solution. Activated carbon materials mainly include activated carbon (AC) and activated carbon fibers (ACF). As an excellent adsorbent, activated carbon is mainly determined by its unique adsorption surface structure and chemical properties.
Activated carbon materials have stable chemical properties, high mechanical strength, acid, alkali and heat resistance, are insoluble in water and organic solvents, can be reused, and have been widely used in chemical industry, environmental protection, food processing, metallurgy, drug refining, military chemical protection and other fields. At present, the modified activated carbon materials are widely used in sewage treatment, air pollution control and other fields, and show more and more attractive prospects in the treatment of environmental pollution.
More than 80% - 90% of the activated carbon is composed of carbon elements, which is also the reason why the activated carbon is a hydrophobic adsorbent. In addition to carbon elements, there are also two kinds of admixtures: one is chemically combined elements, mainly oxygen and hydrogen, which remain in the carbon due to incomplete carbonization, or in the process of activation, foreign non-carbon elements are chemically combined with the surface of activated carbon, such as when activated by water vapor, the surface of activated carbon is oxidized or oxidized by water vapor; Another kind of admixture is ash, which is the inorganic part of activated carbon.
