B As Food Colorants

Cochineal and its derivatives are reemerging today as food colorants because of their superior technological properties (stability, clarity, and desirable hue) and the influence of the natural trend (Table 9.9).56 Carmine lakes are more cost-effective as colorants than carminic acid and have color shades similar to those obtained with the synthetics ponceau 4R and amaranth. Moreover, stability is good under light exposure, but is lowered in the presence of heat, pH, air, and irradiation. In addition, carmine dyes are resistant to oxidation and not affected by SO2. Commercial presentations include a spray-dried form in maltodextrin or preparations with propylene ch2oh
