E290 - Carbon Dioxide or Carbon Dioxide

E290 CARBON DIOXIDE OR CARBON DIOXIDE

Carbon dioxide is a natural gas that is part of the normal constituents of the atmosphere, being the product of the respiration of plants and animals, including humans; it is also produced by our body during the alcoholic fermentation processes of sugars.

As an additive, carbon dioxide is usually used:

• in drinks to make them fizzy, like water, coca-cola or some wines;
• in packaging processes in controlled atmosphere of fruit and vegetable foods: with this process, in cold stores, oxygen levels are reduced in favor of carbon dioxide levels, thus preventing the fermentation and oxidation of food and consequently limiting its maturation. In doing so, the fruits remain more crispy, more consistent and retain the characteristic aromas, minimizing the development of mold;
• in packaging processes in modified / protected atmosphere (together with nitrogen): this method is used to hinder microbial development and to prevent food oxidation. It is a widely used technique, because it prolongs the shelf-life of foods. Initially, this process was limited only to fresh pasta, baked goods, sliced ​​in tubs; but then, given the good results obtained, this practice has been extended to all food categories. The mixture of carbon dioxide and nitrogen, considered inert gases, used in this process, does not interfere in any way with the characteristics of the food, keeping its color, taste and consistency unaltered.
• as a propellant in gas containers (eg whipped cream).

No negative side effects associated with the intake of carbon dioxide as an additive are known.
