Useful sourness: the effect of citric acid on the human body
What is citric acid
Citric acid is an organic acid derived from citrus fruits such as lemon, lime, oranges. When we eat these fruits, we feel a sour taste - this is due to the content of citric acid in them.
The history of citric acid begins in 1874, when the Swedish chemist Carl Scheele first obtained it from the unripe fruits of lemongrass. Since then, they have learned how to extract it on an industrial scale. By the way, the main producers of citric acid are Russia and China.
It is used as a food supplement, in everyday life - for example, to remove scale, in cosmetics - to lighten the tone and get rid of freckles, in pharmaceuticals - to stabilize metabolism and lose weight.

Many people confuse ascorbic acid and citric acid. And it sounds similar, and the usual "ascorbic acid" has a sour taste. But in reality they are different things.Both citric and ascorbic acid are organic acids of natural origin. The key difference is that ascorbic acid is the active compound of what we take as vitamin C. And the citric acid in vitamin C tablets is only used for flavor.
Ascorbic acid is the active compound of vitamin C, its very essence.
Lemon - only a sour taste in the composition of "ascorbic acid".
