Embodiment 1

[0066] 1. Pass the exiting tobacco powder (from the packaging workshop of China Tobacco Gold Leaf Manufacturing Center in Henan Province) through a 100-mesh sieve, take out the small particle size exiting tobacco powder, add deionized water according to the mass ratio of material to liquid 1:12, and store at 70°C Heat and extract at constant temperature for 1 hour, filter and sterilize at 121° C. for 15 minutes with high temperature and damp heat to obtain smoke powder extract.

[0067] 2. Using Brettanomyces isolated from distiller's yeast as a fermentation strain, a single colony was picked from the slope and inoculated into 50 mL of tobacco powder extract, and incubated for 24 hours with constant temperature and vibration to obtain tobacco powder seed liquid.

[0068] 3. According to the volume ratio of 1:50, inoculate the tobacco powder seed solution into a fermenter containing 3L of tobacco powder extract, and incubate at a constant temperature with vibration for 48 hours ...

Abstract

The invention discloses a treatment method for improving the quality of expanded tobacco shreds, and the method comprises the following steps: (1) carrying out thermal extraction treatment on withdrawn tobacco powder to obtain a tobacco powder extracting solution; (2) preparing a tobacco powder culture medium from the tobacco powder extracting solution, and inoculating aroma-enhancing microorganisms to obtain a tobacco powder seed solution; (3) inoculating the tobacco powder seed solution into the tobacco powder extracting solution to obtain a fermented tobacco powder extracting solution; (4)diluting the fermented tobacco powder extracting solution, and uniformly applying the diluted fermented tobacco powder extracting solution to the expanded tobacco shreds to obtain pretreated expandedtobacco shreds; (5) standing the pretreated expanded tobacco shreds to obtain pretreated expanded tobacco shreds; (6) drying the pretreated expanded tobacco shreds to obtain standby expanded tobacco shreds; and (7) balancing the standby expanded tobacco shreds to obtain the optimized expanded tobacco shreds. The fermented tobacco powder extracting solution is added into the expanded tobacco shreds, so that the aroma amount can be effectively increased. In addition, the fermented tobacco powder extracting solution still contains a certain amount of viable bacteria, and continuous fermentation can be achieved after the fermented tobacco powder extracting solution is added into expanded tobacco shreds.

Description

technical field [0001] The invention relates to the field of cigarette manufacturing, and more particularly, relates to a treatment method for improving the quality of expanded shredded tobacco. Background technique [0002] Expanded shredded tobacco refers to tobacco leaves or tobacco stems after conditioning and rebaking, which are prepared by expansion technology using expansion agents such as carbon dioxide and nitrogen, and have the characteristics of large volume and light weight. Expanded shredded tobacco is mainly used to increase the filling value of shredded tobacco in cigarettes, reduce costs and improve combustibility, etc., and is widely used in the cigarette industry. [0003] However, because expanded shredded tobacco is usually prepared from lower-quality upper tobacco leaves and tobacco stems, the content of flavor substances after expansion is low and the chemical composition is uncoordinated, resulting in low smoking aroma and strong stimulation of expande...
