Sec.  184.1240  Carbon dioxide.

    (a) Carbon dioxide (empirical formula CO2, CAS Reg. No. 
124-38-9) occurs as a colorless, odorless, noncombustible gas at normal 
temperatures and pressures. The solid form, dry ice, sublimes under 
atmospheric pressure at a temperature of -78.5 [deg]C. Carbon dioxide is 
prepared as a byproduct of the manufacture of lime during the 
``burning'' of limestone, from the combustion of carbonaceous material, 
from fermentation processes, and from gases found in certain natural 
springs and wells.
    (b) The Food and Drug Administration is developing food-grade 
specifications for carbon dioxide in cooperation with the National 
Academy of Sciences. In the interim, the ingredient must be of purity 
suitable for its intended use.
    (c) In accordance with Sec.  184.1(b)(1), the ingredient is used in 
food with no limitations 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 leavening agent as defined in Sec.  
170.3(o)(17) of this chapter; a processing aid as defined in Sec.  
170.3(o)(24) of this chapter; and a propellant, aerating agent, and gas 
as defined in Sec.  170.3(o)(25) of this chapter.
    (2) The ingredient is used in food at levels not to exceed current 
good manufacturing practice.
    (d) Prior sanctions for this ingredient different from the uses 
established in this section do not exist or have been waived.
