  § 73.125   Sodium copper chlorophyllin.

  (a) Identity. (1) The color additive sodium copper chlorophyllin is a green to black powder prepared from chlorophyll by saponification and replacement of magnesium by copper. Chlorophyll is extracted from alfalfa ( Medicago sativa ) using any one or a combination of the solvents acetone, ethanol, and hexane.

 ?。?) 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.

 ?。╞) 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.

 ?。?) Solvent residues (acetone, ethanol, and hexane), not more than 50 parts per million, singly or, in combination.

 ?。?) Total copper, not less than 4 percent and not more than 6 percent.

  (4) Free copper, not more than 200 parts per million.

 ?。?) Lead (as Pb), not more than 10 parts per million.

 ?。?) Arsenic (as As), not more than 3 parts per million.

  (7) Mercury (as Hg), not more than 0.5 part per million.

 ?。?) Ratio of absorbance at 405 nanometers (nm) to absorbance at 630 nm, not less than 3.4 and not more than 3.9.

 ?。?) Total copper chlorophyllins, not less than 95 percent of the sample dried at 100 °C for 1 hour.

 ?。╟) 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.

  (d) Labeling requirements. The label of the color additive and any mixtures prepared therefrom shall conform to the requirements of §70.25 of this chapter.

 ?。╡) Exemption from certification. Certification of this color additive is not necessary for the protection of the public health, and therefore batches thereof are exempt from the certification requirements of section 721(c) of the act.

 ?。╞)質(zhì)量規(guī)格:葉綠酸銅鈉應(yīng)符合下列規(guī)格,除了指明的雜質(zhì)在規(guī)定范圍內(nèi)之外,不得含有在現(xiàn)行GMP條件下可以避免的其它雜質(zhì)。

  (1)水分,不超過(guò)5%;

  (2)溶劑殘留(丙酮、乙醇和己烷),單一或組合時(shí)不超過(guò)50mg/kg;

 ?。?)銅離子總量,不少于4%且不超過(guò)6%;

  (4)自由銅離子,不超過(guò)200mg/kg;

  (5)鉛(以Pb計(jì)),不超過(guò)10mg/kg;

  (6)砷(以As計(jì)),不超過(guò)3mg/kg;

  (7)汞(以Hg計(jì)),不超過(guò)0.5mg/kg;

 ?。?)405nm吸光度與630nm吸光度比值A(chǔ)405/A630,不低于3.4且不超過(guò)3.9;

 ?。?)葉綠酸銅總量,100℃干燥1h后,不低于95%。

 ?。╟)使用和限制條件:葉綠酸銅鈉可安全地用于柑橘類(lèi)干飲料混合物的著色,在干混合物中的量不能超過(guò)0.2%。

 ?。╠)標(biāo)簽標(biāo)注方式:本著色劑和任何由本著色劑制備的混合物的標(biāo)簽應(yīng)遵循本章§70.25的要求。
