This invention discloses an aroma fitter for fenugreek tincture based on key aroma components and synergistic aroma characteristics, and its applications. Based on analytical studies of the aroma components and aroma characteristics of high-quality fenugreek tincture, the aroma fitter identifies key aroma characteristics such as caramel sweetness, freshness, fruitiness, nutty aroma, roasting aroma, and sourness, and determines the contributing characteristic compounds and their synergistic proportions within each aroma characteristic. The composition contains key components such as acetic acid, trans-2-pentenal, propyl butyrate, phenethyl acetate, 2-hexanone, ethyl palmitate, benzaldehyde, 2,5-dimethylpyrazine, and 3-hydroxy-4,5-dimethyl-2(5H)furanone, which are precisely formulated to achieve a high degree of consistency with natural fenugreek tincture in aroma structure and olfactory characteristics. This invention not only provides a realistic and layered aroma fitter formulation but can also be applied to the food and daily chemical industries, providing stable and harmonious fenugreek characteristic aromas, thus possessing significant practical application value.

The invention discloses an aerosol generating product, an aerosol generating system and a manufacturing method of a fuming section, and belongs to the technical field of aerosol generation. In the embodiment of the invention, the pore channel penetrating through at least one end surface of the aerosol generating product along the flow direction of the aerosol in the aerosol generating product is formed in the fuming section of the aerosol generating product, and the pore channel is filled with the aroma filler, so that once the aerosol generating product is placed in the accommodating cavity of the aerosol generating device, the aroma can be generated; the hole channel can be communicated with the containing cavity and the suction end of the aerosol generating product at the same time, fragrance is continuously released through the aroma filler filled in the hole channel, essence and fragrance in the fuming section can be slowly and evenly released, the fuming amount and the fragrance amount are lasting and stable, and therefore the suction quality is improved.

The present application relates to a kind of expression osmanthus source carotene cleavage dioxygenase (OfCCD1) recombinant yeast engineering bacteria and its application in tobacco flavoring, the amino acid sequence of OfCCD1 is as shown in SEQ ID NO:1.The present application is based on pPICZ alpha A vector constructs recombinant overexpression dioxygenase CCD Pichia engineering bacteria, and the application of the engineering bacteria in improving the content of tobacco beta-ionone and improving the sensory quality of tobacco.Compared with multiple plant source dioxygenase engineering bacteria constructed in the same group, the osmanthus source OfCCD1 engineering bacteria constructed is applied to carotene precursor in tobacco, and aromatic substance is cracked to generate fragrance marker beta-ionone, relative to untreated group, it is increased by 57.1%, significantly improve the quality of aroma, satisfaction, salivation and other indicators, and the application effect is best.The method for improving the quality of tobacco of the present application is mild, green and efficient, and has good application prospect.
