The present disclosure relates to a method for producing fermented green coffee beans and fermented green coffee beans produced thereby, the method including: (A) a step of freezing green coffee beans at −10 to −25° C.; (B) a step of immersing the frozen green coffee beans in water for 3 to 10 hours; (C) a step of taking out the green coffee beans immersed in the water, removing the water and leaving the beans to stand for 5 to 15 hours while supplying air at 20 to 30° C.; (D) a step of sterilizing the green coffee beans and then inoculating the same with a strain to anaerobically ferment the same; and (E) a step of sterilizing and then drying the anaerobically fermented green coffee beans. When the fermented green coffee beans are roasted into coffee beans, aroma and taste may be improved and odor may be removed.

The present invention relates to a method for producing fermented and vacuum-treated coffee using Kopi Luwak enterobacteria, in which the coffee contains a low concentration of caffeine and a high concentration of γ-aminobutyric acid (GABA). According to the present invention, the fermented and vacuum-treated coffee produced using Kopi Luwak enterobacteria according to the present invention has advantages in that it is produced by rapid fermentation, uniquely smells like caramel, chocolate, grass, etc., unlike unfermented green coffee beans, and has a reduced bitter taste and a deep and heavy taste with an appropriate sour taste.

The present invention includes a method of myceliating coffee beans including sterilizing the coffee beans, preparing a liquid tissue culture including an aliquot of fungal liquid tissue culture derived from liquid state fermentation, and inoculating the coffee beans with the fungal liquid tissue culture. Next, the step of enabling mycelium growth on the coffee includes controlling temperature, humidity, and sterility of the environment. The aliquot of fungal liquid tissue culture is optionally agitated to form hyphael conglomerations of mycelium having sizes of less than 1 mm in diameter.

Provided is a method for production of an improved myceliated green tea with increased herbal/vegetal/hay or floral notes, the method including the steps of providing green tea leaves, providing a fungal aqueous culture with Cordyceps sinensis fungus, inoculating the green tea leaves with at least a portion of the fungal liquid tissue culture; and culturing the fungal mycelium with the green tea leaves to produce the improved myceliated green tea, and teas produced by the methods disclosed.

Disclosed herein is a method for processing green coffee beans, including: (1) loading unroasted green coffee beans on a mesh-like plate, placing in a container the mesh-like plate having the green coffee beans loaded thereon, introducing water into the bottom of the container so as to be spaced apart from the lower surface of the mesh-like plate, and closing the lid of the container to seal the container; (2) placing the sealed container in a heating cabinet, and then steaming the green coffee beans at low temperature for 10 to 12 days while maintaining the internal temperature of the heating cabinet at 70 to 80 C.; and (3) opening the lid of the container, and then drying the steamed green coffee beans for 4 to 6 days while maintaining the internal temperature of the heating cabinet at 38 to 43 C.
