Abstract

The invention discloses a preparation method of pure rice-koji added with Chinese medical herbs and application thereof. The preparation method is characterized by comprising the following steps of: inoculating aspergillus flavus QJ into a PDA (Potato Dextrose Agar) slant culture medium, culturing at 25-30 DEG C for 7-10 days, selecting slant colonies with uniform surface growth and thick spore layers, transplanting onto the PDA slant culture medium again, culturing at 25-30 DEG C for 5-7 days to obtain slant strains, and preserving at 4 DEG C for 15-30 days; carrying out amplification culture on the aspergillus flavus QJ, preparing spore suspension of the aspergillus flavus QJ, adding Chinese medical herbs into spread cooled steamed rice, and culturing medicinal koji for 3-4 days under the conditions that temperature is 35-40 DEG C and humidity is 90-95% so as to obtain the ure rice-koji added with the Chinese medical herbs, wherein the diastatic power is 979.348-1738.99 U / g dry koji; and the liquefaction force is 21.37-59.43 U / g dry koji. Compared with the rice-koji without Chinese medical herbs, the diastatic power of the medicinal koji is increased by 25.89-41.61%; the liquefaction force of the medicinal koji is increased by 31.97-56.122%; therefore, the pure rice-koji has great development value and wide market prospect.

Traditional medicinal koji is generally made from rice flour or rice bran, mixed with Chinese herbal medicines, inoculated with mother koji, and made through billet making, powder coating, indoor cultivation, and room drying. Its finished song is white or light yellow, with uniform hyphae, no black, and special aroma (Zhang Wenxue. Overview of Chinese Wine Culture [M]. Beijing: China Light Industry Press, 2011). Medicinal koji has a long history. For example, a small song in Qionglai, Sichuan, is famous in the southwest. A total of 72 Chinese medicinal materials are added to the koji, and the medicinal materials used are crushed and dried into fine powder for use. ...
