Essence |
L-Ascorbic Acid or E300 is an organic compound (a vitamin) that occurs naturally in various fruits (like lemons, grapefruits, oranges, etc.) and vegetables (chili peppers, kale, broccoli, etc.) and has powerful antioxidant properties. |
Names |
Vitamin C, 3-Keto-L-Gulofuranolactone, 3-Oxo-Laevo-Gulofuran, INS 300, Laevo-Ascorbic acid, E300, L-Ascorbic Acid, and others. |
Sourcing |
Commercially, it is typically made out of D-Glucose. |
Manufacturing |
To create the L-Ascorbic Acid, D-Glucose gets hydrogenated by a nickel catalyst. This creates D-Sorbitol which then undergoes microbiological oxidation (Acetobacter xylinum). This creates L-Sorbose. This is then converted to 2-keto-L-Gulonic Acid through oxidation and further converted to either the additive or the Sodium Ascorbate. A solution of Sodium Ascorbate can be applied to cation exchange resins to create the Ascorbic Acid (without the L-). |
Application |
Antioxidant (natural, water-soluble), acidity regulator, and preservative. |
