 PART 73--LISTING OF COLOR ADDITIVES EXEMPT FROM CERTIFICATION--Table of Contents
 
                             Subpart A--Foods
 
 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.
