Embodiment 1

[0027] In 100ml of aqueous solution, dissolve 2g of maltol, slowly add 0.88g of anhydrous calcium chloride (dissolved in a very small amount of water), stir for 20min, use pH test paper to detect the pH value of the solution before and after adding calcium chloride, and compare the solution after adding calcium salt The pH value decreased significantly, indicating that maltol and calcium ions had a coordination effect.

Embodiment 2

[0029] In 100ml of aqueous solution, dissolve 2g of maltol, slowly add 4.55g of zinc sulfate heptahydrate (dissolved in a very small amount of water), stir for 20min, compare and smell the smell of the solution before and after adding zinc sulfate heptahydrate with scented paper, and find that the latter The burnt sweet aroma of maltol is obviously lighter, indicating that there is less free maltol.

Embodiment 3

[0031] According to the proportion of 1% of the mass of the cut tobacco (based on the weight of maltol), the blended essence (the ratio of calcium chloride and maltol is 1:1, ethanol solvent, normal temperature) was evenly added to the cut tobacco, and rolled into experimental cigarettes. The comparison is the cigarette rolled by shredded tobacco of the alcohol solution of equal concentration of maltol (without adding calcium chloride), which is made according to the same conditions. All cigarettes are balanced in moisture for 48 hours, and the equilibrium conditions are: temperature (22±1)°C, relative humidity (60±2)%. Smokers from China Tobacco Hunan Industrial Co., Ltd. tested and smoked the cigarettes. The results: Compared with the control sample, the test sample cigarettes released the characteristic aroma of maltol (sweet burnt aroma) before and after a few puffs, and the release was more uniform. (Remarks: In order to more intuitively verify the conclusion whether the ...

Abstract

The invention discloses ortho-hydroxyl ketone prepared essence and application thereof. The essence is characterized in that: [1 / 2-1] mole of calcium (or zinc)-containing compound is added into every mole of ortho-hydroxyl ketone fragrant substance, preparation is performed in a common solvent of essence for cigarettes at a certain temperature, and the pH value is adjusted appropriately, so that the volatility of the ortho-hydroxyl ketone fragrant substance is remarkably lowered under the coordination between the ortho-hydroxyl ketone fragrant substance and the calcium (or zinc)-containing compound, the sniffing fragrance is lightened remarkably, and the stability is enhanced; after being prepared, the essence can be applied to perfuming of cigarettes; and during the burning of a cigarette, the ortho-hydroxyl ketone fragrant substance can be effectively released. By adopting the essence, the problems of poor stability (easy deliquescence, easy degeneration and difficult storage) as well as high volatility, heavy sniffing fragrance, low threshold value, non-uniform fragrance release and impermanency when applied to tobacco, and the like of the fragrant substance are solved. The prepared essence is suitable for flavor blending of tobacco and perfuming of cigarettes.

Description

technical field [0001] The invention belongs to the technical field of tobacco flavors and fragrances, and specifically relates to solving the problems of strong volatility, heavy smell, perishability, uneven aroma release after aromatization, and unsustainable aroma existing in the application of a class of aroma raw materials in cigarettes. Background technique [0002] In cigarette flavoring and application, some flavoring materials with strong volatility and low threshold can play a good role in cigarette smoke, but the problems in practical application of such flavoring materials have always troubled flavoring workers. As described in the present invention, o-hydroxyketone fragrances mainly include four types of fragrances such as o-hydroxyfuranones, o-hydroxypyrones, methylcyclopentenolones, and methylcyclohexenolones, all of which belong to cyclic The α-diketone enol structure, although they can impart burnt sweet and toasted aroma to the smoke, is an important aroma ...
