Professional coffee knowledge exchange more coffee bean information please follow the coffee workshop (Wechat official account cafe_style)

In the past two days, a piece of news about a California court ruling that Starbucks has put a "possible carcinogenic label" has been scanned on moments. The ruling was based on the fact that coffee contains large amounts of acrylamide, which is prone to cancer.

The court's ruling is not aimed at Starbucks alone, but against the coffee industry as a whole. In the latest news, Starbucks China sent a media statement to thepaper.cn on the evening of March 31, saying that the National Coffee Industry Association had issued an announcement on the court's ruling, insisting that coffee was a safe drink and that the court's decision misled the public.

Yesterday, this article, which was exposed by Starbucks' biggest scandal, went viral on moments. Fortunately, most people are rational, and rumors stop at the wise.

@ this cup of coffee is not too cold. There are too many carcinogens in the world. Who doesn't live to death? we can't just let coffee carry this pot.

@ God's will to drink coffee acrylamide causes cancer to drink 300-400 cups of coffee a day to reach the dose, so that caffeine poisoning will die before drinking cancer. In other words, normal people will die if they drink 400 glasses of water a day. A friend just gave me popular science.

@ Xu saw those alarmist people constantly forwarding the idea that coffee causes cancer in the moments this morning. I don't even bother to go in there! Just think of it as the remarks of those who don't like coffee. Just like fans, there are people who like this star, and there must be people who hate ta! There are too many carcinogens, so how old are you to ration two cups a day?

@ sincere , I laughed, I do not believe that those who sue do not drink coffee, do not eat fried food, is really 6666

@ when hairy children come to China, Chinese people are already immune.

This eye-catching title, for coffee lovers, like a nightmare, is coffee really undrinkable? Fortunately, the coffee workshop did not make a mistake and kept an objective and impartial attitude when reporting the matter.

How much acrylamide is there in a cup of coffee?

What is acrylamide and how much impact does it have on the human body?

Acrylamide is a toxic chemical. In 2002, Swedish scientists first discovered that deep-fried potato chips, French fries and other chemical reactions are easy to form acrylamide. Since then, scientists have discovered that many foods, especially those cooked at high temperatures that are rich in carbohydrates, contain acrylamide.

According to a circular issued by the State Food and Drug Administration in July 2014, experts from the State Food Safety risk Assessment Center and the School of Food Science and Nutrition Engineering of China Agricultural University believe that acrylamide is neurotoxic to both humans and animals; it also has reproductive toxicity, mutagenicity and carcinogenicity.

To put it more popularly, scholars have only found that this substance may cause cancer in animals, but it is not clear what kind of cancer it can cause in humans.

In 2005, at the 64th meeting of the Joint Food and Agriculture Organization of the United Nations / World Health Organization expert Committee on Food Additives (JECFA), 6752 detection data of acrylamide in food from 2002 to 2004 were obtained from 24 countries, of which the average content of acrylamide in coffee (brewed) was 13 (μ g/kg) and the highest was 116 (μ g / kg). The average content of acrylamide in coffee (roasted, ground, unboiled) was 288 (μ g/kg), and the highest content was 1291 (μ g/kg).

How do you calculate? Let's estimate in the most conservative way, for example, a person of 70 kilograms has a daily acrylamide tolerance of 182 micrograms (70 × 2.6 = 182). In other words, he needs to drink at least 404 cups of black coffee (182 / 0.45,404) a day to drink a full dose of carcinogenic. Similarly, a 50-kilogram coffee family must drink 318 cups of black coffee a day in order to ingest the carcinogenic dose of acrylamide. I believe that it is impossible for ordinary people to drink such a large amount of coffee in one day.

10g of caffeine is about the same as 28 Starbucks cups of coffee!

Show me 28 Starbucks a day, so don't worry about it.

To talk about toxicity without the dose is to play hooligans!

Acrylamide in roasted Coffee

In the article "Research status of acrylamide in roasted Coffee" published by Xu Tongyu and Zeng Shaodong, etc., it is pointed out that the main factors affecting the formation of acrylamide in coffee are coffee type, roasting temperature and time. For example, when the roasting temperature is 120-180 ℃, lowering the processing temperature and heating time can reduce the final production of acrylamide. When the roasting temperature is above 200℃, the higher the temperature is and the longer the time is, the lower the final content of acrylamide is.

It means that you are advised to drink coffee made from lightly roasted coffee beans, which will reduce the intake of acrylamide, such as coffee made by the front street hand.

Apart from the dose, talking about toxicity is all hooliganism.

In addition, acrylamide exists not only in coffee, but also in fried and overbaked foods. Try to eat as little fried food as possible. (the unit of content is micrograms per kilogram)

Boiled grain and noodles (113 samples): 15

Roasted and fried vegetables (39 samples): 59

Fresh vegetables (45 samples): 4.2

Coffee extract (20 samples): 1100

Decaffeinated coffee (26 samples): 688

Fried chicken leg (10 samples): 81-271

Finally, the expert concluded: the dose is not large, you can drink one or two cups a day!

Therefore, in fact, we do not have to worry too much, normal people eat and drink, will not cause harm to health. Compared with drinking one or two cups of black coffee, it may make more sense to eat less plant fat, less sugar and less salt, less fried, barbecue and less cookies and potato chips.

Do what you have to do, drink a single drink or drink a single drink.

Should I drink Starbucks or Starbucks?

The Chinese have long been immune, ha.
