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 
foods.
    (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 
Cosmetic Act.
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 
restrictions:
    (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.
