In the natural environment, ascorbic acid can be found in all types of citrus fruits, rose hips, kiwi, black currants, tomatoes, red pepper, lettuce leaves, onions. The bulk of animals and plants synthesize ascorbic acid. Only primates are capable of receiving the substance only from food, since the synthesis of this substance does not occur in their organisms. It is possible to produce ascorbic acid in an industrial way. For this, glucose is synthesized.

According to its physico-chemical characteristics, ascorbic acid looks like a white or light yellow crystalline powder, which is perfectly soluble in water and alcohol and has a characteristic sour taste. The chemical formula of the food additive E300 is as follows: C6H8O6.

Properties additives E300

A well-known vitamin C, which was first isolated in pure form in 1928, is a popular form of ascorbic acid.
