CHAPTER I--FOOD AND DRUG ADMINISTRATION, DEPARTMENT OF HEALTH AND HUMAN
PART 73_LISTING OF COLOR ADDITIVES EXEMPT FROM CERTIFICATION--Table
Sec. 73.170 Grape skin extract (enocianina).
(a) Identity. (1) The color additive grape skin extract (enocianina)
is a purplish-red liquid prepared by the aqueous extraction (steeping)
of the fresh deseeded marc remaining after grapes have been pressed to
produce grape juice or wine. It contains the common components of grape
juice; namely, anthocyanins, tartaric acid, tannins, sugars, minerals,
etc., but not in the same proportions as found in grape juice. During
the steeping process, sulphur dioxide is added and most of the extracted
sugars are fermented to alcohol. The extract is concentrated by vacuum
evaporation, during which practically all of the alcohol is removed. A
small amount of sulphur dioxide may be present.
(2) Color additive mixtures for food use made with grape skin
extract (enocianina) may contain only those diluents listed in this
subpart as safe and suitable in color additive mixtures for coloring
(b) Specifications. Grape skin extract (enocianina) shall conform to
the following specifications:
Pesticide residues, not more than permitted in or on grapes by
regulations promulgated under section 408 of the Federal Food, Drug, and
Lead (as Pb), not more than 10 parts per million.
Arsenic (as As), not more than 1 part per million.
(c) Uses and restrictions. Grape skin extract (enocianina) may be
safely used for the coloring of still and carbonated drinks and ades,
beverage bases, and alcoholic beverages subject to the following
(1) It may not be used to color foods for which standards of
identity have been promulgated under section 401 of the act unless
artificial color is authorized by such standards.
(2) Its use in alcoholic beverages shall be in accordance with the
provisions of parts 4 and 5, title 27 CFR.
(d) Labeling requirements. The label of the color additive and any
mixtures prepared therefrom intended solely or in part for coloring
purposes shall conform to the requirements of Sec. 70.25 of this
chapter. The common or usual name of the color additive is ``grape skin
extract'' followed, if desired, by ``(enocianina)''.
(e) Exemption from certification. Certification of this color
additive is not necessary for the protection of the public health, and
therefore batches thereof are exempt from the certification requirements
of section 721(c) of the act.
