Objective: This research is to study the production of natural red pigment by Monascus purpureus TISTR3615 in the submerged and solid-statefermentation system using Pathumthani-1 rice as a carbon source.Methods: The antioxidant activity of the red pigment was evaluated in vitro 2,2-diphenyl-1-picrylhydrazyl (DPPH), ABTS radical scavenging assay,and ferric-reducing antioxidant power (FRAP) assay, including total phenolic compound.Results and Discussion: The maximum of red pigment production was 0.55±0.02/ml (OD 680 nm) after incubation at 30°C for 24 days. Theantioxidant activity based on inhibition DPPH (%), ABTS radical scavenging activity (%), and FRAP activity (mM Fe2+/g) was 97.80±1.51,68.64±0.46, and 0.32±0.021, respectively. The total phenolic content was 164.78±2.82 μg GAE/mg.Conclusion: It was estimated that Monascus pigments, leading to nutraceutical and pharmaceutical applications, cosmetic industry, and foodindustry.
