| Summary: | It is noted that nowadays, halal products are gaining wider recognition as a new benchmark for
safety and quality assurance. As a consequence of these additional pigment needs, the demand
in isolated natural colorants has increased as compared with synthetic dyes. The aim of the
research is to explore new sources of pigments to be used as halal food colorants. This quest
is not only directed in finding natural alternatives for synthetic dyes, but also with the aim
to discover new taxons for the pigment production, for instance from microalgae. Therefore,
a total of six freshwater algae species were evaluated quantitative and qualitatively using
HPLC for carotenoids pigment. Three main carotenoids were identified in Chlorella fusca,
Chlorella vulgaris, Selenastrum capricornutum, Pandorina morum, Botryococcus sudeticus
and Chlorococcum sp. which are lutein, β-cryptoxanthin and β-carotene. The ratio of these
carotenoids varies between species where lutein was detected substantially higher in Chlorella
fusca (69.54±11.29µg/g DW); β-cryptoxanthin in Pandorina morum (1.24±0.33 µg/g DW)
whereas β-carotene in Chlorella vulgaris (18.42±9.2 ug/g DW). The significant outcome of
the research will be new findings of new natural carotenoid pigment sources as potential food
colorants and bioactive compounds which can be beneficial to halal health promoting products
industry, food products and dye technology which covers not only the Shariah requirement, but
also the hygiene, purification and safety aspects. |
