Abstract
The aim of the present work was to investigate the feasibility of jackfruit seed powder as a substrate for the production of pigments by Monascus purpureus in solid-state fermentation (SSF). A pigment yield of 25 OD Units/g dry fermented substrate was achieved by employing jackfruit seed powder with optimized process parameters such as 50% initial moisture content, incubation temperature 30 °C, 9 × 10 4 spores/g dry substrate inoculum and an incubation period of seven days. The color of the pigments was stable over a wide range of pH, apparently due to the buffering nature of the substrate, which could be a significant point for its scope in food applications. To the best of our knowledge this is the first report on pigment production using jackfruit seed powder in solid-state fermentation (SSF).
