No. 97–53–0）, oleoresins, and natural extractives obtained from clove buds, leaves, and stems.
（b） Clove bud oil, clove leaf oil, clove stem oil, and eugenol meet the specifications of the “Food Chemicals Codex,” 4th ed. （1996）, pp. 104–105, which is incorporated by reference in accordance with 5 U.S.C. 552（a） and 1 CFR part 51. Copies 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 Safety and Applied Nutrition's Library, Food and Drug Administration, 5100 Paint Branch Pkwy., College Park, MD 20740, or at the National Archives and Records Administration （NARA）.

（2） Optical rotation of the volatile oil between -2° and 0°；
（3） Refractive index of the volatile oil between 1.527 and 1.538 at 20 °C;
（4） Specific gravity of the volatile oil between 1.036 and 1.060; and
（5） Residual solvent free, except those solvents that are GRAS or within tolerance levels as specified in part 173, subpart C, of this chapter.
（c） Clove and its derivatives are used as flavoring agents and adjuvants as defined in §170.3（0）（12） of this chapter.
