Patent ID: 8703456

Claim:
A method for manufacturing red mold dioscorea comprising the steps of: (1a) adding a specific amount of water to a raw material of a dioscorea to make the raw material of the dioscorea and the water be a specific ratio ranged from 1:10 to 1:200, wherein the raw material of the dioscorea is a dried dioscorea containing a sulfur content is below 160 ppm; (2a) proceeding a sterilization process to the raw material of the dioscorea and then cooling the product down to a specific temperature; (3a) inoculating a Monascus spp. to the sterilized dioscorea; (4a) culturing the inoculated dioscorea under a specific cultural temperature ranged from 25° C. to 37° C. and a specific shaking frequency ranged from 50 rpm to 300 rpm for 8˜20 days; wherein the S 2 included by the specific sulfur content below 160 ppm would contribute an acidic culturing condition with pH 3-4, and the acidic culturing condition being able to increase the production of a yellow pigment of secondary metabolites produced by the Monascus -inoculated dioscorea; (5a) proceeding an anaerobic treatment to the product of step (4a) for 48 hours, wherein the anaerobic treatment is carried out by culturing the inoculated dioscorea under 100% CO 2 condition; and (6a) drying the product of step (5a) to a specific water content, wherein the specific water content is below 15%.
