The invention has the following beneficial effects:
1. the preparation method is a new method which is obviously different from the traditional tobacco shred preparation method, can effectively overcome the defect that the traditional tobacco shred can not be subjected to internal quality adjustment, can selectively enrich and apply aroma components according to the aroma characteristics of tobacco leaves, and effectively improves the internal quality of the tobacco shred.
2. The tobacco shred product formed by the invention can improve the state that the existing cigarette which is not heated and burnt has single aroma and unsatisfactory intrinsic smoking taste, and can reform the aroma quality, thereby greatly improving the use value of the tobacco shred product.
3. The microwave heating and the subsequent flavoring and moistening treatment process are adopted, so that the quality and richness of the tobacco fragrance are improved, and raw materials with higher quality and richer fragrance are provided for cigarettes and heating non-combustible tobacco products.
4. The tobacco shreds prepared by the method have wide application range, are particularly suitable for heating non-burning cigarettes, and can be used as a tobacco shred raw material with unique style to be added into the tobacco shreds of the existing traditional burning and smoking type cigarettes, thereby effectively improving the filling value of the cigarettes, reducing harmful ingredients and improving the smoking quality of the cigarettes. Meanwhile, the cut tobacco prepared by the method in the traditional cigarette can effectively reduce the addition of common cut tobacco due to the direct shredding, thereby achieving the purposes of reducing the consumption of tobacco leaves and improving the production efficiency.
