Abstract
ABSTRACTRed radish anthocyanin extract (RAE) was investigated to color brined cherries as an alternative to FD&C Red No. 40. Primary and secondary bleached cherries were colored using two concentrations of RAE (600 and 1200 mg/L syrup, C1 and C2) and FD&C Red No. 40 (200 ppm). Color and pigment stability of secondary bleached cherries and syrup colored with RAE were evaluated during storage (25°C). CIELAB, chroma and hue angle, showed that RAE imparted color extremely close to that of FD&C Red No. 40, for > 6 mo storage. Monomeric anthocyanin degradation followed first‐order kinetics, with half‐lives of 29 and 33 wk for syrups colored with RAE C1 and RAE C2, respectively. Higher anthocyanin concentration exerted a protective effect on color stability. Exposure to light slightly accelerated L*, a*, and monomeric anthocyanin degradation.
