| Abstract: | Erythorbic acid (EA), also known as D-ascorbic acid (IUPAC name: (5R)-5-[(1R)- 1,2-dihydroxyethyl]-3,4-dihydroxy-5-methylfuran-2(5H)-one) is a diprotic acids and an epimer of vitamin C (L-ascorbic acid). As compared to L-ascorbic acid its activity is 5% and its chemical structure is shown in Fig. 3.4.1. It is a crystalline solid of white to slightly pale color, that gradually blackens upon subjection to light. Its melting point is 164°C and it is freely soluble in water and ethanol. While in solution, it quickly, degrades in the presence of air, it is relatively stable in air, but when it is in the dry state (Burdock, 2005; EFSA, 2016). [excerpt] |
