§ 73.169 Grape color extract.
（a） Identity. （1） The color additive grape color extract is an aqueous solution of anthocyanin grape pigments made from Concord grapes or a dehydrated water soluble powder prepared from the aqueous solution. The aqueous solution is prepared by extracting the pigments from precipitated lees produced during the storage of Concord grape juice. It contains the common components of grape juice, namely anthocyanins, tartrates, malates, sugars, and minerals, etc., but not in the same proportion as found in grape juice. The dehydrated water soluble powder is prepared by spray drying the aqueous solution containing added malto-dextrin.
（2） Color additive mixtures for food use made with grape color extract may contain only those diluents listed in this subpart as safe and suitable in color additive mixtures for coloring foods.
（b） Specifications. Grape color extract 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 color extract may be safely used for the coloring of nonbeverage food, except that it may not be used to color foods for which standards of identity have been promulgated under section 401 of the act, unless the use of added color is authorized by such standards.
（d） Labeling. The color additive and any mixtures prepared therefrom intended solely or in part for coloring purposes shall bear, in addition to the other information required by the act, labeling in accordance with the provisions of §70.25 of this chapter.
（e） Exemption from certification. Certification of this color additive is not necessary for the protection of the public health, and therefore batches are exempt from the certification requirements of section 721（c） of the Act.

§73.169 葡萄色素提取物
（a）特性：
（1）著色劑葡萄色素提取物，系由美洲產(chǎn)的康考特葡萄（Concord grape）制得的花色素苷類葡萄色素的水溶液，或由該水溶液制得的水溶性脫水粉末。水溶液由提取康考特葡萄汁在貯存期間所形成的沉淀物中的色素而得。其中含有葡萄汁的普通成分，包括花色素苷類、酒石酸鹽類、蘋果酸鹽類、糖類和無機(jī)鹽類等，但并不含有葡萄汁中的所有成分。水溶性的脫水粉末由水溶液加入麥芽糊精后噴霧干燥而成。
（2）用葡萄色素提取物配成的食用著色劑混合物，只能選用合適本分部所列的可安全地用于食品著色的著色劑混合物稀釋劑。
（b）質(zhì)量規(guī)格：葡萄色素提取物必須符合下列質(zhì)量指標(biāo)：殺蟲劑殘留量不得超過聯(lián)邦食品、藥物和化妝品法第408節(jié)中所規(guī)定的在葡萄中或表皮上的殘留量。鉛（以Pb計），不超過10mg/kg，砷（As計），不超過1mg/kg。
（c）使用和限制條件：葡萄色素提取物可安全地用于非飲料食品類的著色。但不能用于本法規(guī)第401節(jié)中所頒布的已確定標(biāo)準(zhǔn)的食品的著色，除非所加入的色素是此標(biāo)準(zhǔn)所允許的。
（d）標(biāo)簽標(biāo)注方式：本著色劑和任何由本著色劑所配制成的混合物，擬單獨(dú)使用或起部分著色效果時，其標(biāo)簽應(yīng)符合本章§70.25中的要求。
（e）免除產(chǎn)品證書：本著色劑免除產(chǎn)品證書以保護(hù)公眾健康。所生產(chǎn)的每批產(chǎn)品也免除按法規(guī)721（c）中所規(guī)定的需要產(chǎn)品證書。
