Method for improving sensory quality of cut rolled stem using ganoderma lucidum fermentation broth

A method for improving a sensory quality of a cut rolled stem using a Ganoderma lucidum fermentation broth, comprising the following steps:

• step 1, a fermentation broth preparation:
• subjecting Ganoderma lucidum to a first-stage cultivation and then to a second-stage expanded cultivation in a fermentation tank to obtain a fungal solution, and filtering the fungal solution to obtain a clear fermentation broth;
• step 2, conducting a pretreatment on a tobacco stem to obtain a pretreated tobacco stem or the cut rolled stem, wherein the pretreatment is one or more treatments of a sieving, a stem washing and soaking, a heating and humidifying, a stem storage, and a shredding;
• step 3, a fermentation broth application:
• applying the clear fermentation broth to the pretreated tobacco stem or the cut rolled stem;
• step 4, a solid-state fermentation:
• subjecting an applied tobacco stem or an applied cut rolled stem to the solid-state fermentation to obtain a fermented tobacco stem or a fermented cut rolled stem;
• and
• step 5, drying the fermented tobacco stem or the fermented cut rolled stem.
