Flavouring essences for tobacco and preparation thereof

Abstract

The invention relates to a cigarette-used essence and a preparation method thereof, which takes 3-methyl-pentanoic acid and menthol as raw materials, wherein, the quantity ratio of 3-methyl-pentanoic acid and menthol is between 1.25 to 1 and 2.25 to 1. Benzene is taken as a water-carrying agent and methyl-benzenesulfonic acid as a catalyst; heating temperature for reaction is between 120 DEG C and 140 DEG C; time for reaction is 1h to 6h; 3-methyl-menthyl valerate is obtained. The 3-methyl-menthyl valerate, namely the cigarette-used essence, is a novel menthyl subtane with potential fragrance; ester prepared from 3-methyl-pentanoic acid and natural product menthol belongs to a mentholated essence in terms of the odor type and structure and has lower volatility than menthol; and therefore, after entering cigarettes during essence adding process, the ester slowly decomposes during the burning process of the cigarettes and then evenly releases 3-methyl-pentanoic acid and menthol, thereby realizing the purpose of balancing the pH value of the cigarettes and improving the aftertaste of the cigarettes and smoke quality of the cigarettes.

Problems solved by technology

However, due to the unpleasant smell of 3-methylvaleric acid, it is difficult to directly use it for flavoring; and both 3-methylvaleric acid and menthol are relatively volatile spices, directly adding to cigarettes is not only easy to volatilize naturally, but also smokes easily. Due to uneven volatilization when smoking, it is easy to cause adverse effects on cigarette smoke
