Grape color extract
Anthocyanins are obtained by maceration or extraction with sulphited water, acidified water, carbon dioxide, methanol or ethanol from the strains of vegetables and edible fruits, with subsequent concentration and/or purification if necessary. Anthocyanins contain common components of the source material, namely anthocyanine, organic acids, tannins, sugars, minerals etc., but not necessarily in the same proportions as found in the source material.
Blackcurrant extract is obtained from blackcurrant pomace by aqueous extraction. The main coloring principles are four anthocyanins (cyanidin 3-rutinoside, delphinidin 3-rutinoside, cyanidin 3-glucoside, delphinidin 3-glucoside). Grape skin extract occurs as a red to purple powder or liquid concentrate. It is prepared by aqueous extraction of grape marc remaining from the pressing of grapes to obtain juice. 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. Butterfly pea flower extract is a dark blue liquid prepared by the aqueous extraction of dried butterfly pea flowers from Clitoria ternatea and contains anthocyanins as the principal coloring component.
Anthocyanins are used to color beverages, confectionary, desserts, ice cream, fruit preparations, bakers jam and non-standard jellies and preserves, sherbets, ices, pops, raspberry, yogurt, gelatin desserts, candy, and bakery fillings and toppings.
Commission Regulation (EU) No 23/2012
Grape Skin Extract (INS No 163(ii)) is added to foods and beverages at concentrations up to a maximum permitted level (MPL) as adopted by the Codex Alimentarius Commission. There are more than 60 food categories for which MPLs for grape skin extract have been adopted in the General Standard of Food Additives (GSFA).
