Sodium Ascorbate or Monosodium l-ascorbate or l-Ascorbic acid monosodium salt or Vitamin C sodium salt
Specifications of Sodium Ascorbate USP Grade:
C6H7NaO6 --- 198.11
l-Ascorbic acid, monosodium salt;
Monosodium l-ascorbate CAS 134-03-2.
DEFINITION
Sodium Ascorbate contains NLT 99.0% and NMT 101.0% of sodium ascorbate (C6H7NaO6), calculated on the dried basis.
Optical Rotation, Specific Rotation: Acceptance criteria: +103° to +108°
pH: 7.0 to 8.0
Loss on Drying: Dry a sample in a suitable vacuum drying tube, using phosphorus pentoxide as the desiccant, at 60C for 4 h: it loses NMT 0.25% of its weight.
Specifications of Sodium Ascorbate FCC Food Grade:
Vitamin C Sodium; Sodium L-Ascorbate
C6H7NaO6 Formula weight 198.11
INS: 301 CAS: 134-03-2
DESCRIPTION
Sodium Ascorbate occurs as a white to yellow, crystalline powder that does not darken on exposure to light. One gram is soluble in 2 mL of water. The pH of a 1:10 aqueous solution is about 7.5.
Function: Antioxidant; meat curing aid; nutrient.
REQUIREMENTS
Identification:
A. A 1:50 aqueous solution slowly reduces alkaline cupric tartrate at 25C, and does so more readily upon heating.
B. Add 4 drops of methylene blue to 2 mL of a 1:50 aqueous solution acidified with 0.5 mL of 0.1 N hydrochloric acid, and warm to 40C. The deep blue color disappears almost completely within 3 minutes.
C. Dissolve 15 mg of sample in 15 mL of a 1:20 trichloroacetic acid:water solution, add about 200 mg of activated charcoal, shake vigorously for 1 minute, and filter through a small fluted filter, returning the filtrate, if necessary, until clear. Add 1 drop of pyrrole to 5 mL of the filtrate, agitate gently until dissolved, and then heat in a water bath at 50C. A blue color appears.
D. A sample gives positive tests for Sodium.
Assay: Not less than 99.0% and not more than 101.0% of C6H7NaO6 after drying.
Lead: Not more than 2 mg/kg.
Loss on Drying: Not more than 0.25%.
Optical (Specific) Rotation [α]D25C: Between +103° and +108°.
