Method for improving inapplicable upper tobacco leaf raw material quality

The invention discloses a method for improving inapplicable upper tobacco leaf raw material quality. According to the method, inapplicable upper tobacco leaf raw materials are placed in an ethanol solution to be soaked, then vacuum decompression processing is conducted, and next solid-liquid separation is conducted; after the inapplicable upper tobacco raw materials obtained after the solid-liquid separation is conducted are dried, the product formula processing process can be conducted. The method is easy to operate and low in cost, the inapplicable upper tobacco raw materials processed through the method still have better forming and processing performance, the inherent sensory quality is obviously improved, the utility value of the inapplicable upper tobacco leaves in cigarettes is increased, and the inventory pressure of the inapplicable upper tobacco leaves is effectively relieved for cigarette companies.
