Abstract

The invention relates to a sun-cured tobacco extract used for microwave-expanded shredded stems, a preparation method and application thereof, and belongs to the technical field of tobacco processing. The preparation method includes the following steps: adding ethanol with a concentration of 50% to 75% to the water extract of sun-dried tobacco after chitosan sedimentation, extracting and stratifying, collecting and concentrating the stratified supernatant to prepare oriental tobacco Style feed liquid; add water to the layered lower layer solution, mix and stir to prepare a solution; finally use a 100nm ceramic membrane to control the protein, lignin and other substances in the solution, and then concentrate it for microwave expansion. The sun-cured tobacco extract, the density is 1.15 ~ 1.20g / ml. The extract prepared by this method not only has no obvious smell of sun-dried smoke, but also can effectively improve the aroma, smoke concentration and thickness of microwave-expanded shredded stems, significantly reduce woody gas, and effectively improve the usability and adaptability of microwave-expanded shredded stems sex.

Description

technical field [0001] The invention relates to a preparation method of an extract of sun-cured tobacco, especially a preparation method of an extract of sun-cured tobacco used for microwave-expanded shredded stems, and also relates to the extract of sun-cured tobacco obtained by the preparation method and its application, belonging to the field of tobacco processing . Background technique [0002] With the continuous improvement of microwave expansion of tobacco stems and its filament forming technology, microwave expanded shredded stems have been widely used in cigarette production. However, due to the low dry matter content of microwave-expanded stalks, there are generally defects in sensory quality such as insufficient aroma and smoke concentration, obvious miscellaneous gases such as woody and scorched, and a prominent burning sensation in smoke, which seriously restricts microwave-expanded stalks. The usage ratio and application range of silk in cigarettes. In order ...
