Coffee capsules : health hazard ?

Coffee capsules - danger furane

Are coffee capsules dangerous ? What are the differences between the coffee capsule and other types of coffee ?

Coffee capsule contains much more of furan (a potentially carcinogenic substance) that the coffee powder from the traditional coffeemaker, According to a Spanish study. Javier Santos, Department of analytical chemistry at the University of Barcelona, explains that “This is not the same thing to prepare a coffee in a traditional coffee maker, in a coffee maker or espresso capsules, because they lead to different levels of furan”.

What are the different identified levels ?

Furan concentrations :

Quantities of furan based on the type of coffee

  • Coffee capsule : 117 to 244 ng/ml (nanograms per millilitre, 1 NG = 109 g)
  • Espresso : 43 to 146 ng/ml
  • Coffee filter coffee : 20 to 78 ng/ml and 14 to 65 ng/ml for decaffeinated coffee
  • Instant coffee : 12 to 35 ng/ml

That is what the furan ?

Furan is a colorless volatile organic compound used in some industries for the manufacture of chemical substances. This substance can also be found in low concentrations in food heat treated such as foods canned or potted. Various mechanisms can be the source of the formation of Furan in food, and it is based on the natural presence of various triggers compounds which are subject to a thermal deterioration or chemical rearrangements during food processing.” [1]

“In may 2004, the Food and Drug Administration of the United States (FDA) has detected low levels of Furan in a wider variety of foods than had been reported previously, more often in food subjected to a heat treatment such as canning or canning.” [1]

Of after Health Canada, the main foods containing high levels of furan are : coffee, soups, stews and chilis containing meat, canned pasta dishes. Note that found also at high rates in the jars for babies with meat and vegetables.

Effects of furan on health

“The international agency for research on Cancer (IARC) has classified as furan potentially carcinogenic to humans.” [1]

The risks to humans are at the moment still poorly known. Studies are underway to better know the effects of small doses of furan we ingest. In 2010, the JECFA (Joint international Committee FAO.WHO expert on food additives) has concluded that furan is worrying for health and that the research, who are current, are a priority.

How is it that there are more Furan in capsules ?

Furan, that is a very volatile compound, remains in capsules which are hermetically closed. The machine uses water under high pressure and which, with the speed of the process entails Furan in the drink.

There is apparently little risk to health

The study estimated that the daily intake of furan, in Barcelona, is 0.03 to 0.38 µg/kg body weight (microgram, 1µg = 106g).

Researchers will want reassuring, should be according to them, drink 20 from cafés of capsules per day so that there is danger to health, reports Futura - sciences.com. Well before arriving at toxic doses of furan, adverse effects of caffeine will be felt.

It should be noted that l’EFSA has assessed the exposure of a European between 0.53 to 0.66 µg/kg body weight per day, While the FDA has assessed him to 0.26µg/kg.

There are two ways to lower the rate of Furan in coffee

The report explains that a long roasting time (20 minutes against 10/15 minutes) and what a less hot water (140° C against 200 / 220 ° C) have the effect of reducing the rate of Furan in coffee.

For all other foods should know that once in the open air (cooking in a pan, recipient open, etc.) furan evaporates in the same way, thereby reducing its content.

Seen the side “top of the range” the thing, I think that the brand could react a little more actively to such an announcement, rather than saying that the dose is dangerous until 20 capsules per day…

@Régine : It is well marked in the article that there is little risk to health… It is therefore not a new very alarmist, but it is a risk that should be noted anyway.

I am interested in the words of Lilli because my sister comes to bequeath me its nespresso who has already a few years in the wing (the model is even more on the site). I find good coffee but there no body (consistency). Nevertheless the danger appeals to me and I would like that Lilli says when she says that”just leave the coffee”…

I am in the competition for quite some time, at Capmundo the capsule is pierced and is contained in a bag airtight so easier to leave the capsule is “rest” as said Lili but also not too because oxygen affect the quality.
The all-alloy does not augur good in all ways.

FOR MY PART I PREFER COFFEE COFFEE MAKER (bio) D as much as J IMAGINE the side chemical cafes in aluminum CAPSULES.
IT INNOVATES, IT INNOVATES BUT W ITHOUT THE SLIGHTEST CONSIDERATION FOR CONSUMERS, WHICH FOR MANY, IT IS TRUE, DO S INTEREST QU TO NOVELTIES AND ARE ONLY THE BOEOTIANS IN MATTERS D EATING !!!…
