Embodiment 1

[0019] (1) Add 18g of ammonia water into the brown reaction bottle, add 45g of fructose to dissolve it while shaking, then cover the lid and pre-react the solution at room temperature of 15°C for 6h;

[0020] (2) Add 100ml of sodium hydroxide-methanol solution with a concentration of 2.5% to the above reaction solution to carry out catalytic reaction. After reacting for 20 minutes, place the reaction bottle in the refrigerator for 48 hours;

[0021] (3) Take out the reaction bottle, add 40ml of 10% sodium hydroxide-methanol solution, stir the solution with a glass rod until the precipitate is fully separated, and separate the precipitate (product) and the filtrate by suction filtration under reduced pressure. After the filtrate was concentrated to 20 ml under reduced pressure, 10 ml of 10% sodium hydroxide-methanol solution was added to precipitate the remaining product. The above products were combined and washed with anhydrous methanol and anhydrous ethanol respectively, and...

Embodiment 2

[0023] As described in Example 1, the refrigerated time of step (2) is changed to 24h, and other operations are the same as Example 1, and the product obtained is also light yellow odorless fructosamine powder, and the productive rate is 78%.

Embodiment 3

[0025] As described in Example 1, the refrigerated time of step (2) is changed to 72h, and other operations are the same as Example 1, and the product obtained is also light yellow odorless fructosamine powder, and the productive rate is 85%.

Abstract

Synthesis of fructosamine perfume compound and flavoring use of tobacco are disclosed. It is carried out by taking fructose and ammonia water as material and catalytic synthesizing in sodium hydrate-methyl alcohol solution system. It achieves low cost, simple synthetic process and high output. It can be used for additive of tobacco.

Description

technical field [0001] The invention relates to a synthesis method and an application method of a tobacco flavor compound, in particular to a method for synthesizing a fructosamine flavor compound and a tobacco application method, and belongs to the technical field of tobacco. technical background [0002] Fructosamine is a derivative of fructose. It usually appears as an intermediate product of Maillard reaction in the baking process of food. It is a latent aroma compound and is unstable. It is easy to undergo Amadori molecular rearrangement, Heinz molecular rearrangement and Strecker degradation reaction. Generate small molecular aroma compounds such as heterocyclic rings, so that the roasted food or tobacco products will present characteristic aromas such as roasting. [0003] Fructosamine compounds are not easy to synthesize, and are usually obtained by reacting fructose with amino acids, but the reaction is not easy to control, and there are many by-products, and the mi...
