Abstract

The invention belongs to the technical field of tobacco processing and biomass utilization transformation, in particular to a treatment method and application of anaerobic solid-state fermented tobacco stems. Intensified fermentation pretreatment: cut the recovered tobacco stems into 1-5cm long fragments, add 0.5-1 times the quality of water, then insert the seed liquid, and carry out solid-state fermentation for 5-30 days under anaerobic and normal temperature conditions to obtain Fermented tobacco stems; transformation and utilization of fermented tobacco stems: add 3-6 times the quality of water to fermented tobacco stems, then add seed liquid and cellulase, and anaerobically ferment at 45-55°C for 72 hours to complete anaerobic conversion process. After enhanced bacterial solid-state anaerobic fermentation, the reduction of cell wall substances can increase the content of reducing sugars in the tobacco stem material and reduce irritation.

Description

technical field [0001] The invention belongs to the technical field of tobacco processing and biomass utilization transformation, in particular to a treatment method and application of anaerobic solid-state fermented tobacco stems. Background technique [0002] Tobacco stem is a very important part of tobacco leaves, and its weight is about 25% of the whole tobacco leaf. The pectin content accounts for 12%-20% of the tobacco stem content. During the process of smoking cigarettes, the pectin content is high, which will cause When burning, it produces a strange smell. The water-insoluble substances in the tobacco stems are mainly cell wall substances, including pectin and cellulose. The evaluation results show that: cellulose has burning paper smell; pectin has woody smell, heavy miscellaneous gas, oral irritation, poor aftertaste and other burning and smoking disadvantages, and will also change the state of smoke; too high protein content will have burning feather smell, whic...
