Embodiment 1
[0023] Cut persimmon leaves into thin strips of 0.2-1.0 cm, weigh 55kg persimmon leaves, 30kg cornmeal, 7kg soybean powder, 7kg bran, and 1kg sucrose, mix well, and add water to make the water content reach 65%. Put the mixed material into a 17×45cm polypropylene plastic bag, each bag contains 0.8Kg (wet weight), compact it slightly, seal it with a plastic collar and cotton, and sterilize at 0.15MPa for 90min. When the temperature of the material drops to 30°C, add 40ml of 10-day-old Ganoderma lucidum liquid strain to each bag, and cultivate in the dark at 25-30°C for 26 days. Take the solid fermentation product out of the bag and dry it at 80°C, crush it into 1-2mm particles, the color of the product is tea-brown, it has a unique scent of Ganoderma lucidum, the total phenol content is 4.6mg / g, and the scavenging rate of DPPH free radicals 92.3%.
Embodiment 2
[0025] Cut persimmon leaves into thin strips of 0.2-1.0cm, weigh 65kg persimmon leaves, 24kg cornmeal, 5kg soybean powder, 5kg bran, 1kg sucrose, mix well, add water to control the water content at 55%, and mix well The material was put into a glass bottle, compacted slightly, sealed with plastic paper, and sterilized at 0.15MPa for 90min. Inoculate when the material temperature drops to 30° C., insert 10-day-old Ganoderma lucidum liquid strain, the inoculum size is 10%, and the rest are the same as in Example 1. The total phenol content of the obtained product is 4.3 mg / g, and the DPPH free radical scavenging rate is 90.2%.
Embodiment 3
[0027] Cut persimmon leaves into thin strips of 0.2-1.0 cm, weigh 70kg persimmon leaves, 21kg cornmeal, 4kg soybean powder, 4kg bran, 1 bran sucrose, and add water to control the water content at 50%. Put the mixed material into a polypropylene plastic bottle, compact it slightly and leave a certain gap, and sterilize at 0.15MPa for 90min. Wait for the temperature of the material to drop to 30° C. to insert 15% liquid strains, and cultivate in the dark at 25-30° C. for 30 days, and the rest are the same as in Example 1. The total phenol content of the obtained product is 4.0 mg / g, and the DPPH free radical scavenging rate is 89.2%.
