Sec. 172.5  General provisions for direct food additives.
 
 
    (a) Regulations prescribing conditions under which food additive 
substances may be safely used predicate usage under conditions of good 
manufacturing practice. For the purposes of this part, good 
manufacturing practice shall be defined to include the following 
restrictions.
    (1) The quantity of the substance added to food does not exceed the 
amount reasonably required to accomplish its intended physical, 
nutritive, or other technical effect in food.
    (2) Any substance intended for use in or on food is of appropriate 
food grade and is prepared and handled as a food ingredient.
    (b) The existence of a regulation prescribing safe conditions of use 
for a food additive shall not be construed to relieve the use of the 
substance from compliance with any other provision of the Act.

             Analytical Specification for Petroleum Naphtha
 
                          general instructions
 
    All glassware should be scrupulously cleaned to remove all organic 
matter such as oil, grease, detergent residues, etc. Examine all 
glassware, including stoppers and stopcocks, under ultraviolet light to 
detect any residual fluorescent contamination. As a precautionary 
measure, it is recommended practice to rinse all glassware with purified 
isooctane immediately before use. No grease is to be used on stopcocks 
or joints. Great care to avoid contamination of petroleum naphtha 
samples in handling and to assure absence of any extraneous material 
arising from inadequate packaging is essential. Because some of the 
polynuclear hydrocarbons sought in this test are very susceptible to 
photo-oxidation, the entire procedure is to be carried out under subdued 
light.
 
                                apparatus
 
    Separatory funnels. 250-milliliter, and 2,000-milliliter capacity, 
equipped with tetrafluoroethylene polymer stopcocks.
    Erlenmeyer flask. 125-milliliter with 24/40 standard taper neck.
    Evaporation flask. 250-milliliter capacity all-glass flask equipped 
with 24/40 standard taper stopper having inlet and outlet tubes to 
permit passage of nitrogen across the surface of the container liquid to 
be evaporated.
    Condenser. 24/40 joints, fitted with drying tube, length optional.
    Spectrophotometric cells. Fused quartz cells, optical path length in 
the range of 5,000 centimeters 0.005 centimeter; also for 
checking spectrophotometer performance only, optical path length in the 
range 1,000 centimeter 0.005 centimeter. With distilled 
water in the cells, determine any absorbance difference.
    Spectrophotometer. Spectral range 250-400 m[mu] with spectral slit 
width of 2 m[mu] or less; under instrument operating conditions for 
these absorbance measurements, the spectrophotometer shall also meet the 
following performance requirements:

---------------------------------------------------------------------------
 
    \1\ As determined by procedure using potassium chromate for 
reference standard and described in National Bureau of Standards 
Circular 484, Spectrophotometry, U.S. Department of Commerce, (1949). 
The accuracy is to be determined by comparison with the standard values 
at 290, 345, and 400 millimicrons. The procedure is incorporated by 
reference. Copies of the material incorporated by reference are 
available from the Center for Food Safety and Applied Nutrition (HFS-
200), Food and Drug Administration, 5100 Paint Branch Pkwy., College 
Park, MD 20740, or available for inspection at the Office of the Federal 
Register, 800 North Capitol Street, NW., suite 700, Washington, DC 
20408.
---------------------------------------------------------------------------
 
Wavelength repeatability, 0.2 millimicron.
Wavelength accuracy, 1.0 millimicron.
 
    Ultraviolet lamp. Long wavelength (3400-3800A deg.).
 
                                reagents
 
    Isooctane (2,2,4-trimethylpentane). Use 180 milliliters in a 250-
milliliter Erlenmeyer flask, add 1 milliliter of purified n-hexadecane, 
insert the head assembly, allow nitrogen gas to flow into the inlet tube 
and connect the outlet tube to a solvent trap and vacuum line in such a 
way as to prevent any back flow of condensate into the flask. The 
contents of the flask are evaporated on a steam bath until 1 milliliter 
of residue remains. Dissolve the 1 milliliter of hexadecane residue in 
isooctane and make up to 25 milliliters. Determine the absorbance in a 
5-centimeter path length cell compared to isooctane as reference. The 
absorbance should not exceed 0.01 per centimeter path length between 
280-400 m[mu]. If necessary, isooctane may be purified by passage 
through a column of activated silica gel (Grade 12, Davidson Chemical 
Co., Baltimore, Md., or equivalent) or by distillation.
    Methyl alcohol, A.C.S. reagent grade. Use 10 milliliters and proceed 
as with isooctane. The absorbance per centimeter of path length should 
be 0.00 between 280-400 m[mu]. Methyl alcohol may be purified by simple 
distillation or by refluxing in the presence of potassium hydroxide (10 
grams/2 liters) and zinc dust (25 grams/2 liters) for 3 hours followed 
by distillation.
    n-Hexadecane, 99 percent olefin-free. Dilute 1.0 milliliter of n-
hexadecane to 25 milliliters with isooctane and determine the absorbance 
in a 5-centimeter cell compared to isooctane as reference between 280-
400 m[mu]. The absorbance per centimeter path length shall not exceed 
0.00 in this range. Purify, if necessary, by percolation through 
activated silica gel or by distillation.
    Sodium borohydride. 98 percent.
 
[[Page 43]]
 
    Water. All distilled water must be extracted with isooctane before 
use. A series of three successive extracts of 1.5 liters of distilled 
water with 100-milliliter portions of isooctane is satisfactory.
 
                                procedure
 
    Determination of ultraviolet absorbance. Add a 25-milliliter aliquot 
of the hydrocarbon solvent together with 1 milliliter of hexadecane to 
the 125-milliliter Erlenmeyer flask. While flushing with nitrogen, 
evaporate to 1 milliliter on a steam bath. Nitrogen is admitted through 
a 81-milliliter outer-diameter tube, drawn out into a 
21-centimeter long and 10.5-millimeter inner-
diameter capillary tip. This is positioned so that the capillary tip 
extends 4 centimeters into the flask. The nitrogen flow rate is such 
that the surface of the liquid is barely disturbed. After the volume is 
reduced to that of the 1 milliliter of hexadecane, the flask is left on 
the steam bath for 10 more minutes before removing. Add 10 milliliters 
of purified isooctane to the flask and reevaporate the solution to a 1-
milliliter volume in the same manner as described above, except do not 
heat for an added 10 minutes. Repeat this operation twice more. Let the 
flask cool.
    Add 10 milliliters of methyl alcohol and about 0.3 gram of sodium 
borohydride. (Minimize exposure of the borohydride to the atmosphere; a 
measuring dipper may be used.) Immediately fit a water-cooled condenser 
equipped with a 24/40 joint and with a drying tube into the flask, mix 
until the sodium borohydride is dissolved, and allow to stand for 30 
minutes at room temperature, with intermittent swirling. At the end of 
this time, disconnect the flask and evaporate the methyl alcohol on the 
steam bath under nitrogen until sodium borohydride begins to drop out of 
solution. Remove the flask and let it cool.
    Add 6 milliliters of isooctane to the flask and swirl to wash the 
crystalline slurry. Carefully transfer the isooctane extract to a 250-
milliliter separatory funnel. Dissolve the crystals in the flask with 
about 25 milliliters of distilled water and pour this also into the 
separatory funnel. Adjust the water volume in the separatory funnel to 
about 100 milliliters and shake for 1 minute. After separation of the 
layers, draw off the aqueous layer into a second 250-milliliter 
separatory funnel. Transfer the hydrocarbon layer in the first funnel to 
a 25-milliliter volumetric flask.
    Carefully wash the Erlenmeyer flask with an additional 6 milliliters 
of isooctane, swirl, and transfer to the second separatory funnel. Shake 
the funnel for 1 minute. After separation of the layers, draw off the 
aqueous layer into the first separatory funnel. Transfer the isooctane 
in the second funnel to the volumetric flask. Again wash the Erlenmeyer 
flask with an additional 6 milliliters of isooctane, swirl, and transfer 
to the first separatory funnel. Shake the funnel for 1 minute. After 
separation of the layers, draw off the aqueous layer and discard. 
Transfer the isooctane layer to the volumetric flask and adjust the 
volume to 25 milliliters of isooctane. Mix the contents well, then 
transfer to the first separatory funnel and wash twice with 50-
milliliter portions of distilled water. Discard the aqueous layers after 
each wash.
    Determine the ultraviolet absorbance of the isooctane extract in 5-
centimeter path length cells compared to isooctane as reference between 
280-400 m[mu]. Determine a reagent blank concurrently with the sample, 
using 25 milliliters of purified isooctane instead of a solvent sample 
and measuring the ultraviolet absorbance of the blank between 280-
400m[mu].
    The reagent blank absorbance should not exceed 0.04 per centimeter 
path length between 280-289 m[mu]; 0.020 between 290-359 m[mu]; and 
0.010 between 360-400 m[mu].
    Determination of boiling-point range. Use ASTM method D86-82, 
"Standard Method for Distillation of Petroleum Products," which is 
incorporated by reference. Copies may be obtained from the American 
Society for Testing Materials, 1916 Race St., Philadelphia, PA 19103, or 
may be examined at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC 20408.
    Determination of nonvolatile residue. For hydrocarbons boiling below 
121  deg.C, determine the nonvolatile residue by ASTM method D1353-78, 
"Standard Test Method for Nonvolatile Matter in Volatile Solvents for 
Use in Paint, Varnish, Lacquer, and Related Products;" for those 
boiling above 121  deg.C, use ASTM method D381-80, "Standard Test 
Method for Existent Gum in Fuels by Jet Evaporation," which methods are 
incorporated by reference. Copies may be obtained from the American 
Society for Testing Materials, 1916 Race St., Philadelphia, PA 19103, or 
may be examined at the Office of the Federal Register, 800 North Capitol 
Street, NW., suite 700, Washington, DC 20408.
 
    (c) Petroleum naphtha containing antioxidants shall meet the 
specified ultraviolet absorbance limits after correction for any 
absorbance due to the antioxidants. Petroleum naphtha may contain 
antioxidants authorized for use in food in an amount not to exceed that 
reasonably required to accomplish the intended effect or to exceed any 
prescribed limitations.

following conditions:
    (a) N-Acetyl-L-methionine (Chemical Abstracts Service Registry No. 
65-82-7) is the derivative of the amino acid methionine formed by 
addition of an acetyl group to the alpha-amino group of methionine. It 
may be in the free, hydrated or anhydrous form, or as the sodium or 
potassium salts.
    (b) The additive meets the following specifications:
    (1) Purity assay, on a dry basis: Minimum 99 percent.
 
[[Page 50]]
 
    (2) Residue on ignition: Maximum 0.1 percent.
    (3) Specific optical rotation [alpha]\20\D: Between -
19 deg. and -23 deg..
    (4) The additive may contain residues of not more than 500 ppm ethyl 
acetate; 50 ppm ethyl alcohol; 10 ppm methyl alcohol; and 10 ppm 
acetone, when used as processing solvents.
    (c) The additive is used or intended for use as a source of L-
methionine to improve significantly the biological quality of the total 
protein in a food containing naturally occurring primarily intact 
vegetable protein that is considered a significant dietary protein 
source, provided that:
    (1) A reasonable daily adult intake of the finished food furnishes 
at least 6.5 grams of naturally occurring primarily intact vegetable 
protein.
    (2) The additive results in a protein efficiency ratio (PER) of 
protein in the finished ready-to-eat food equivalent to casein as 
determined by the method specified in paragraph (d) of this section.
    (3) The use of the additive results in a statistically significant 
increase in the PER as determined by the method described in paragraph 
(d) of this section. The minimum amount of the additive to achieve the 
desired effect must be used, and the increase in PER over the primarily 
intact naturally occurring vegetable protein in the food must be 
substantiated as a statistically significant difference with at least a 
probability (P) value of less than 0.05.
    (4) The amount of the additive added for nutritive purpose shall not 
exceed the level that will provide a total of 3.1 percent L- and DL-
methionine (expressed as the free amino acid) by weight of the total 
protein of the finished food, including the amount naturally present in 
free and combined (as protein) form.
    (5) The additive shall not be added to infant foods or to foods 
containing added nitrites/nitrates.
    (d) Compliance with the limitations concerning PER under paragraph 
(c) of the section shall be determined by the method described in

    The food additive whole fish protein concentrate may be safely used 
as a food supplement in accordance with the following prescribed 
conditions:
    (a) The additive is derived from whole, wholesome hake and hakelike 
fish, herring of the genera Clupea, menhaden, and anchovy of the species 
Engraulis mordax, handled expeditiously and under sanitary conditions in 
accordance with good manufacturing practices recognized as proper for 
fish that are used in other forms for human food.
    (b) The additive consists essentially of a dried fish protein 
processed from the whole fish without removal of heads, fins, tails, 
viscera, or intestinal contents. It is prepared by solvent extraction of 
fat and moisture with isopropyl alcohol or with ethylene dichloride 
followed by isopropyl alcohol, except that the additive derived from 
herring, menhaden and anchovy is prepared by solvent extraction with 
isopropyl alcohol alone. Solvent residues are reduced by conventional 
heat drying and/or microwave radiation and there is a partial removal of 
bone.
