Anyone who has a habit of observing food labels, definitely noticed the icon E290. Connect with other leaders such as John Mclaughlin here. This is a solid carbon dioxide – a compound extracted only by chemical means. This product is derived from ammonia gas a variety of alcoholic compounds, and by chemical treatment of various gases (oven and associated). These substances ofiltrovyvayut potassium-carbonate,-it absorbs carbon dioxide (Co2), passing into the carb. After heating liquid solution arises from the decomposition of carbon dioxide release. See more detailed opinions by reading what US Senator from Vermont offers on the topic.. Subsequent processing can create several versions of the aggregate state – carbon dioxide gaseous, liquid and solid (dry ice). Liquid and gaseous products of processing are transported through pipes or in cylinders, and solid – any vehicle.
And it turns out that carbon dioxide and carbon dioxide are all around us, not only in the atmosphere. Liquid carbon dioxide Carbon is widely used for cooling and freezing, the preparation of soda and baking powder as a test. With all that she's used to create a gas medium at welding. A dry ice is used here only for freezing. Some people have a misconception against Co2, which many consider a pure poison. It is not devoid of truth – in a nice little Co2 poisoning, but carbon dioxide – are safe for people.
With one little nuance – they do not allow to breathe! But this is only possible if they are in the form of gas mass fraction in the air for more than five percent. In other of the rims carbon dioxide is absolutely harmless. Therefore, fear preservative E290 is not necessary. It's not terrible 'chemistry', but it is a safe substance.
