Recently. The topic of coffee causing cancer rushed to the hot search.
The major circles of friends were also this one59 mainstream coffee brandsGroup 2A carcinogens were detectedmessage swiping.
On December 6, the Fujian Provincial Consumer Council conducted a comparative test on 59 freshly made and sold coffees from 20 coffee sales units in Fuzhou City, saying that all of them detected low levels of Class 2A carcinogens, and the samples involved a number of mainstream brands in the market, including different categories such as Americano, latte and flavored latte, basically covering the freshly made and sold coffee products on the market.
In this 59 samples, a low level of class 2A carcinogen "acrylamide" was detected (at present, there are no restrictions or prohibitions on acrylamide in coffee in China).
After seeing it, many coffee fans expressed that they were a little afraid that drinking a cup of coffee would cause cancerHow much acrylamide is in coffee?Are the consequences really that serious?Don't panic just yet!Let's start with the 2A carcinogen "acrylamide", let's start with the ......
What is acrylamide?
Acrylamide is a white crystalline substance that is widely used in the production of polyacrylamide, a chemical product. In 2002, Swedish researchers found for the first time that some fried and grilled starchy foods contain acrylamide, and the amount of acrylamide in food is affected by a variety of factors.
How is acrylamide produced?
Acrylamide is a reducing sugar and certain amino acids found in foodWhen cooking at high temperatures (frying, baking, roasting, etc.)., a substance that is formed incidentally, that is, a by-product of the Maillard reaction.
Acrylamide is widely found in food and can be found in both restaurants and home-cooked foods, especially fried, baked, grilled foods, such asFrench fries, potato chips, bread, biscuits, cookies, chocolate, fritters, oil cakes, twistsWait. In addition to these everyday foods, there's another thing that's easy to overlook** – acrylamide is also found in cigarette smoke.
The amount of acrylamide in different foods
In 2011, the Joint Expert Committee on Food Additives (JECFA) under the Joint Food and Agriculture Organization of the United Nations and the World Health Organization summarized the results of 11,036 analyses from 27 countries from 2004 to 2009, and the acrylamide content of several of our common foods is as follows:
At the same time, JECFA also points out that the acrylamide formed in food is generally stable, but the acrylamide content in coffee decreases with longer storage time.
In fact, the contribution rate of coffee to acrylamide in daily life is not high, according to the assessment of the Hong Kong Centre for Food Safety, the main acrylamide diet of Chinese residents is vegetables, accounting for 484%, which is mainly due to the way of stir-frying. That is, with its tangled acrylamide content in coffee,It's better to start by thinking about breaking unhealthy cooking Xi
Does acrylamide really cause cancer?
Among the four categories of carcinogens announced by the World Health Organization, acrylamide belongs to group 2a carcinogens, that isThere is limited evidence of carcinogenic effects in humans, there is sufficient evidence of carcinogenicity in experimental animals. Animal experiments have found that acrylamide can cause tumors in a variety of organs in rats, including breast, thyroid, adrenal gland, central nervous system, oral cavity, uterus, pituitary gland, etc.
Let's just say. Coffee is still drinkable.
But there's always something wrong with proper control!
Furthermore. Acrylamide at home and abroad.
All have strict control measures in place.
China
In 2005, the former Ministry of Health of China issued the "Announcement on Reducing the Health Hazards Caused by Acrylamide";In 2012, the National Center for Food Safety Risk Assessment released the "Risk Assessment Report on Acrylamide in Food", which analyzes and evaluates the toxicity of acrylamide, the formation of acrylamide in food, and the possible exposure of the human body, and gives control and prevention suggestions. In addition, the national food safety standard "Code for Acrylamide Pollution Control in Food" has been established in 2019 and is being formulated.
abroad
The United States and the European Union have both issued industry guidelines to reduce acrylamide levels. The European Commission issued Directive (EU) 2017 2158 to set out norms for reducing the amount of acrylamide in food.
Codex Alimentarius Commission
The Codex Alimentarius Commission's Code of Practice for the Reduction of Acrylamide in Food (CAC RCP 67-2009) recommends the reduction of acrylamide by consuming raw materials with low reducing sugars and changing food processing and heating.
in everyday life.
We enjoyed the food at the same time.
You should pay attention to the following two points.
1.Try to avoid overcooking food (e.g. too high a temperature or heating it for too long), but make sure it is cooked to ensure that the microorganisms in the food are killed and can avoid causing foodborne illness.
2.Promote a balanced diet, reduce the intake of fried and high-fat foods, and eat more fruits and vegetables.
