US 2026/0117261 A1 · METHOD FOR PREPARING RED MONASCUS PIGMENT AND ITS APPLICATIONS

Abstract

The present invention pertains to the field of natural fermentation pigments and specifically relates to a method for preparing red Monascus pigment and its applications. The method disclosed herein enables an extraction yield of red Monascus pigment of more than 85%. Compared to red Monascus pigments obtained by conventional extraction techniques, the red Monascus pigment prepared by the present method exhibits significantly improved extraction yield, stability, and antioxidant capacity. In particular, the pigment possesses a deep red hue, making it especially suitable for use in baked goods. The improved properties of the pigment facilitate its broader applicability and commercial potential.
