Sec.  184.1007  Aconitic acid.

    (a) Aconitic acid (1,2,3-propenetricarboxylic acid 
(C6H6O6), CAS Reg. No. 000499-12-7) 
occurs in the leaves and tubers of Aconitum napellus L. and other 
Ranunculaceae. Transaconitic acid can be isolated during sugarcane 
processing, by precipitation as the calcium salt from cane sugar or 
molasses. It may be synthesized by sulfuric acid dehydration of citric 
acid, but not by the methanesulfonic acid method.
    (b) The ingredient meets the following specifications:
    (1) Assay. Not less than 98.0 percent of 
C3H3(COOH)3, using the ``Food Chemicals 
Codex,'' 4th ed. (1996), pp. 102-103, test for citric acid, which is 
incorporated by reference in accordance with 5 U.S.C. 552(a) and 1 CFR 
part 51, and a molecular weight of 174.11. Copies of the material 
incorporated by reference are available from the National Academy Press, 
Box 285, 2101 Constitution Ave. NW., Washington, DC 20055 (Internet 
address http://www.nap.edu), or may be examined at the Center for Food

    (2) Melting point. Not less than 195 [deg]C and the determination 
results in decomposition of aconitic acid.
    (3) Heavy metals (as Pb). Not more than 10 parts per million.
    (4) Arsenic (as As). Not more than 3 parts per million.
    (5) Oxalate. Passes test.
    (6) Readily carbonizable substances. Passes the test for citric acid 
of the ``Food Chemicals Codex,'' 4th ed. (1996), pp. 102-103, which is 
incorporated by reference in accordance with 5 U.S.C. 552(a) and 1 CFR 
part 51. The availability of this incorporation by reference is given in 
paragraph (b)(1) of this section.
    (7) Residue on ignition. Not more than 0.1 percent as determined by 
the ``Food Chemicals Codex,'' 4th ed. (1996), pp. 102-103, test for 
citric acid, which is incorporated by reference in accordance with 5 
U.S.C. 552(a) and 1 CFR part 51.
