Abstract: A method for manufacturing and packaging a special-shaped cigarette includes the following steps: designing inner packaging case paper capable of being folded into a special-shaped cigarette accommodating cavity; folding the inner packaging case paper to form the special-shaped cigarette accommodating cavity; filling an interior of the special-shaped cigarette accommodating cavity with an ordinary cigarette; and shelving for a certain period of time, so that a cross section of the ordinary cigarette changes from a circle to a special shape, and the ordinary cigarette is accommodated in the special-shaped cigarette accommodating cavity. A diameter of an inscribed circle of the special-shaped cigarette accommodating cavity is less than a diameter of the ordinary cigarette, and a material of the inner packaging case paper is a paperboard or a food grade PVC sheet.

Abstract: A sensory evaluation method for spectral data of mainstream smoke includes: performing a data enhancement on spectral data of mainstream smoke of a plurality of cigarettes; extracting a shallow spectral characteristic from the spectral data of the mainstream smoke of each cigarette; obtaining a shallow sensory quality result of the spectral data of the mainstream smoke of each cigarette based on the spectral data of the mainstream smoke of each cigarette and the shallow spectral characteristic; extracting deep spatial characteristics from the spectral data of the mainstream smoke of each cigarette; obtaining a deep sensory quality result based on the spectral data of the mainstream smoke of each cigarette and the deep spatial characteristics; obtaining a comprehensive sensory quality result according to the shallow sensory quality result and the deep sensory quality result. The sensory evaluation method achieves accurate screening of unknowns in the mainstream smoke.
