title: Retrograded maize starch used as a medium to enrich Monascus from the air in winter.
abstract: Red pigments extracted from fungus Monascus are used for food coloration in China. Wild-growing Monascus spores are usually enriched in the yeast and mold media in the air, but those media are also favorable for yeast and bacteria. In the paper, Monascus species have grown in retrograded maize starch lain in air outdoors in winter, molds, yeast or bacteria colonies have been absent. Then a medium of the retrograded maize starch for enriching Monascus in the air is explored and its physicochemical properties are determined by ordinary camera photos, NMR, SEM spectra and X-ray diffraction. The lamellar structure of frozen retrograded maize starch, whose interlamellar spacing is about 2μm, provides a favorable condition for Monascus spore to germinate and grow.
