Abstract:
The present paper deals with the chemistry, isolation, separation, characterisation and stabilisation of the Marigold
oleoresin and its application as a natural food colorant. Marigold (Tagetes Erecta L), an ornamental plant belonging to
the composite family, has a rich source of natural antioxidant-Lutein. A natural pigment, xanthophylls offer an
alternative to synthetic dyes as a food colorant, due to its non-toxicity. Chromatographic separations of saponified and
unsaponified oleoresin were performed and Trans-Lutein identified as the major constituent. Well-preserved flowers
exhibit a high yield of Xanthophyll content (105.19 g/Kg) in contrast to the unpreserved flower sample (54.87 g/Kg),
emphasizing the significance of flower preservation in the extraction of xanthophyll. The stability and amount of
xanthophyll also increased from 105.19 g/Kg to 226.88 g/Kg on saponification and subsequent purification with
Ethylene Dichloride

Abstract:
The marine microorganisms are yet to be exploited as a source of natural
pigments for probable utilization in various industries. Hence, in this study focus
was made only on pigment producing marine bacteria for pigment production and
evaluation of the same for some application besides development of an ideal
bioprocess for subsequent indigenous production of the pigment using the same
organism towards ultimate industrial application.
