摘要
Experimental cocktail cherries dyed with carotenoids and commercial cherries were compared by spectrocolorimetry to determine color characteristics and stability. Cherries dyed with canthaxanthin, apocarotenal and oleoresin paprika were more tomato- or orange-red than cherries dyed with Red No. 40, Red No. 3, or carmine. No color bleeding was observed with carotenoid-dyed cherries. The color of cherries dyed with canthaxanthin was stable for 1 year at 4 degrees C. Color stability was not as good in cherries dyed with apo-carotenal but could be improved greatly by addition of ethylenediaminetetraacetic acid (EDTA) and ascorbic acid to preservative solutions in which cherries were stored.
