In this article, we will show you which options are available to you on Amazon and what you should pay attention to when buying. They are the result of a reaction, known as the Maillard reaction, between carbohydrates, unsaturated fatty acids and ascorbic acids or its derivatives. An espresso pot, also known as an espresso maker or Moka pot, is a small pot that you can use to make coffee on the cooker. The study also shows that furan concentrations are lower if coffee is roasted at low temperatures over a longer time (140✬ for 20 minutes) than in coffee roasted under usual conditions (200‐220✬ for 10-15 mins).įuran, like acrylamide, is one of a group of carcinogenic substances that can form when foods and drinks are subject to heat treatment. These estimates were made on the basis of 40 ml cups and an average body weight for coffee drinkers of around 70 Kg. Editors Notes July 15, 2021: Technically known as moka pots, these stovetop coffee makers deliver. Wiki researchers have been writing reviews of the latest stovetop espresso makers since 2015. In order for furan ingestion to exceed the maximum acceptable values, a person would have to drink at least 20 cups of capsule coffee or 30 espressos per day (for the brands with the highest furan content), or 200 instant coffees. Currently, the best stovetop espresso maker is the Bialetti Express. In fact, the team has estimated the amount of furan ingested as a result of coffee consumption in Barcelona, obtaining values of 0.03‐0.38 micrograms/kilogram of body weight, which is less than the maximum acceptable level (2 μg/Kg of body weight). The researcher stresses that, in all these cases, the levels of the substances found are within the limits considered to be "safe" to health. The longer that coffee is exposed to the air in cups or jugs, meanwhile, the more the furan evaporates. "The reason for these higher levels is due to the fact that hermetically-sealed capsules prevent furan, which is highly volatile, from being released, while the coffee makers used to brew this coffee use hot water at higher pressures, which leads to the compound being extracted into the drink," says Javier Santos. The levels of these toxic products were "slightly lower" (12‐35 ng/ml) in instant coffee, but a great deal higher in those made from the capsules of a well-known brand, which showed up higher levels (117‐244 ng/ml). The results, published online in the Journal Food Chemistry, reveal that higher concentrations are found in espresso (43‐146 nanograms/mililitre) than in coffee made in drip coffee makers, both in the case of normal coffee (20‐78 ng/ml) and decaffeinated coffee (14‐65 ng/ml). "Preparing a coffee in a drip coffee maker is not the same as making one in an espresso machine or from capsules, because these give rise to differing levels of furan," Javier Santos, a professor at the Department of Analytical Chemistry at the University of Barcelona and lead author of the study, said.Ĭoncern has risen over recent years about the presence of this compound in foods, because of its toxic and carcinogenic effects in animals, as well as the fact that the International Agency for Research on Cancer has listed it as a possible carcinogen in humans.Īgainst this backdrop, the scientists used an automated analytical method to assess the presence of furan in coffee.
