Sec.  184.1537  Nickel.

    (a) Elemental nickel (CAS Reg. No. 7440-02-0) is obtained from 
nickel ore by transforming it to nickel sulfide 
(Ni3S2). The sulfide is roasted in air to give 
nickel oxide (NiO). The oxide is then reduced with carbon to give 
elemental nickel.
    (b) The Food and Drug Administration is developing food-grade 
specifications for nickel in cooperation with the National Academy of 
Sciences. In the interim, this ingredient must be of a purity suitable 
for its intended use.
    (c) In accordance with Sec.  184.1(b)(1), the ingredient is used in 
food with no limitation other than current good manufacturing practice. 
The affirmation of this ingredient as generally recognized as safe 
(GRAS) as a direct human food ingredient is based upon the following 
current good manufacturing practice conditions of use:
    (1) The ingredient is used as a catalyst as defined in Sec.  
170.3(o)(24) of this chapter.
    (2) The ingredient is used in the hydrogenation of fats and oils as 
defined in Sec.  170.3(n)(12) of this chapter at levels not to exceed 
current good manufacturing practice. Current good manufacturing practice 
includes the removal of nickel from fats and oils following 
hydrogenation.
    (d) Prior sanctions for this ingredient different from the uses 
established in this section do not exist or have been waived.
