Carbon dioxide is a colorless, odorless, non-combustion,
non-flammable gas at the standard atmosphere pressure, which is
widely used in food industry, oil industry, and chemical industry.
Carbon dioxide is a food additive used as a propellant and acidity
regulator in the food industry. Carbon dioxide can be injected into
the drink by increasing pressure to have drinks bubbles, and then
increase the taste when drinking, such as soft drinks, beer. Liquid
and solid carbon dioxide are important refrigerants, especially in
the food industry, where they are employed during the
transportation and storage of ice cream and other frozen foods.
Carbon dioxide has also been widely used as an extinguishing agent
in fixed fire protection systems for local application of specific
hazards and total flooding of a protected space. Carbon dioxide is
used as a welding gas primarily because it is much less expensive
than more inert gases such as argon or helium. Carbon dioxide is
used in the carbon dioxide laser, which is a kind of important
resource of industrial lasers. Plants require carbon dioxide to
conduct photosynthesis. Carbon dioxide in the form of dry ice is
often used in the wine making.
