§ 73.125 Sodium copper chlorophyllin.
(a) Identity.

(2) Color additive mixtures made with sodium copper chlorophyllin may contain only those diluents that are suitable and are listed in this subpart as safe for use in color additive mixtures for coloring foods.
(b) Specifications. Sodium copper chlorophyllin shall conform to the following specifications and shall be free from impurities other than those named to the extent that such impurities may be avoided by good manufacturing practice:
(1) Moisture, not more than 5.0 percent.
(2) Solvent residues (acetone, ethanol, and hexane), not more than 50 parts per million, singly or, in combination.
(3) Total copper, not less than 4 percent and not more than 6 percent.
(4) Free copper, not more than 200 parts per million.
(5) Lead (as Pb), not more than 10 parts per million.
(6) Arsenic (as As), not more than 3 parts per million.
(7) Mercury (as Hg), not more than 0.5 part per million.
(8) Ratio of absorbance at 405 nanometers (nm) to absorbance at 630 nm, not less than 3.4 and not more than 3.9.
(9) Total copper chlorophyllins, not less than 95 percent of the sample dried at 100 °C for 1 hour.
(c) Uses and restrictions. Sodium copper chlorophyllin may be safely used to color citrus-based dry beverage mixes in an amount not exceeding 0.2 percent in the dry mix.
