Sec. 555.100 Alcohol; Use of Synthetic Alcohol in Foods (CPG 7120.10)
BACKGROUND:
Increasing quantities of alcohol (ethyl alcohol) have been made synthetically from
natural gas and petroleum derivatives.
Questions about the suitability of synthetic alcohol for use in manufacturing vinegar
arose as early as l948. By Administration Information Letter No. 90, dated January 28,
l949, the districts were advised that we seriously doubted that a product made from
synthetic alcohol could be appropriately regarded as a type of vinegar.
Early in l957 the Director, Alcohol and Tobacco Tax division, Internal Revenue Service
asked for comment on the suitability of synthetic alcohol for use in foods and drugs. Our
comments in a letter dated February 5, l957, signed by Mr. M. R. Stephens, who was then
Director, Bureau of Enforcement, included the following paragraphs:
"Ethyl alcohol is recognized in the U.S. Pharmacopeia, one of the official drug
compendiums under the Federal Food, Drug, and Cosmetic Act; consequently, ethyl alcohol
intended for drug use must comply with the standards and tests laid down in the
Pharmacopeia. Since the Pharmacopeia does not place any restrictions as to the method of
manufacturing ethyl alcohol, synthetic alcohol which complies with the standards and tests
set forth in the official monograph may legally be distributed for drug use.
"We consider that the situation with respect to foods is different. We believe
that consumers generally expect the alcohol in food products to have been produced from
fermented food substances, such as grains, fruit, etc., and that they do not expect their
foods to contain 'alcohol' produced from petroleum gas.
"For this reason, we have advised inquirers that we do not regard this synthetic alcohol as a suitable food ingredient. This position, however, has not been the subject of any court review.
In reply to many letters from industry and from members of Congress, we consistently
advised that we considered synthetic alcohol unsuitable for food use.
Questions have been raised as to whether we can or should continue to consider
synthetic alcohol unsuitable for food use. In order to secure more information, we wrote
to the Alcohol, Tobacco and Firearms Division, Internal Revenue Service. Their reply
included the following paragraphs:
"Presently, we authorize the manufacture of vinegar from ethyl alcohol synthesized
from natural gas or petroleum derivatives. It is our opinion that most of the distilled
spirits used in the production of vinegar are derived from natural gas and petroleum. When
such alcohol is used in the production of vinegar, we would consider any reference to
'grain alcohol' or 'neutral grain spirits' would be misleading for the alcohol and also
the name 'grain vinegar' would be misleading, except for connoting strength, e.g.,
40-grains.
"When alcohol is used in the production of beverage products, our regulations
require that the source of the alcohol be shown on the label except for cordials and
liqueurs. Incidentally, I might add that most of the alcohol used in the production of
medicinal preparations and flavors is synthetic."
Practically and scientifically, pure ethyl alcohol synthesized from natural gas or
petroleum products does not differ from that obtained by fermentation with subsequent
distillation. Furthermore, foods in which one is used cannot be distinguished objectively
from those in which the other is used.
POLICY:
Synthetic ethyl alcohol may be used as a food ingredient or in the manufacturing of
vinegar or other chemicals for food use, within limitations imposed by the Federal Food,
Drug, and Cosmetic Act, the Alcohol Administration Act, and regulations promulgated under
these acts.
Any labeling reference to synthetic alcohol as "grain alcohol" or
"neutral grain spirits" is considered false and misleading.
