  § 173.280   Solvent extraction process for citric acid.

  A solvent extraction process for recovery of citric acid from conventional Aspergillus niger fermentation liquor may be safely used to produce food-grade citric acid in accordance with the following conditions:

  (a) The solvent used in the process consists of a mixture of n- octyl alcohol meeting the requirements of §172.864 of this chapter, synthetic isoparaffinic petroleum hydrocarbons meeting the requirements of §172.882 of this chapter, and tridodecyl amine.

  (b) The component substances are used solely as a solvent mixture and in a manner that does not result in formation of products not present in conventionally produced citric acid.

  (c) The citric acid so produced meets the specifications of the “Food Chemicals Codex,” 3d Ed. (1981), pp. 86–87, which is incorporated by reference (Copies may be obtained from the National Academy Press, 2101 Constitution Ave. NW., Washington, DC 20418, or may be examined at the National Archives and Records Administration (NARA).

  (d) Residues of n- octyl alcohol and synthetic isoparaffinic petroleum hydrocarbons are removed in accordance with good manufacturing practice. Current good manufacturing practice results in residues not exceeding 16 parts per million (ppm) n- octyl alcohol and 0.47 ppm synthetic isoparaffinic petroleum hydrocarbons in citric acid.

  (e) Tridodecyl amine may be present as a residue in citric acid at a level not to exceed 100 parts per billion.
