Safe natural bio-pigment production by Monascus purpureus using mixed carbon sources with cytotoxicity evaluation on root tips of Allium cepa L.

ABSTRACT: By increasing the undesirable side effects of synthetic food pigments on human health, using safe natural food pigment become an urgent issue. Incorporate corn starch with oils conducted a high impact on red pigment production by Monascus purpureus. Fortification the medium with sesame oil raised the pigment production by 80% and the dry mass by 63% compared with free oil medium. Response surface methodology maximizes the production with 114.6% (12.8 A₅₀₀) using medium constituents (g/l); Sesame oil 5; Corn starch 30; Yeast extract 1.5; KH₂PO₄ 2.5 and MgSO₄.7H₂O 0.1. After evaluating red pigment stability in three common food components, citric acid showed a great effect on residual stability percentage compared with ascorbic an
