The aim of this study is also extended to investigate the possibility of utilization of the separated natural pigments in coloring some well known candy like products such as Lolita which are very famous among children in Egypt. The results revealed that carotenoids were the predominant pigments in samani date wastes. The carotenoids content was about 5.84% (on dry weight basis). The fractionation and identification studies revealed about nine components in the separated carotenoids including lycopene, β-carotene, β-Cryptoxanthin, Canxanthin, Antheraxanthin, Zeaxanthin, Echineone, Violaxanthin, and Lutein.
