FLAVORS FOR TOBACCO AND METHOD FOR ITS PRODUCTION Russian patent published in 2023 - IPC A24B3/12 A24B15/42 

FIELD: flavours for tobacco products.

SUBSTANCE: tobacco flavouring contains a solid acid and a Maillard reaction intermediate, wherein the weight ratio of the solid acid to the Maillard reaction intermediate is from 1:5 to 1:1000. The solid acid is an oxide-based solid acid or a metal salt-based solid acid. The oxide-based solid acid is selected from at least the group consisting of Al₂O₃-SiO₂ based mixed oxides, Al₂O₃ -B₂O₃ based mixed oxides and ZrO₂ -MoO₃ based mixed oxides. The metal salt solid acid is selected from at least the group consisting of metal sulphates and metal phosphates. An intermediate product of the Maillard reaction is obtained as a result of the Maillard reaction of an amino acid and a carbohydrate at a temperature of 50-200°C. The amino acid is selected from at least the group consisting of glycine, alanine, arginine, glutamic acid, leucine and isoleucine. The carbohydrate is selected from at least the group consisting of glucose, fructose, sucrose, lactose, mannose and galactose. The proposed flavour is used in low-temperature cigarettes.

EFFECT: proposed flavour is stable, does not volatilize and does not dissipate at room temperature, during long-term storage of low-temperature cigarettes, the flavour remains persistent and stable during smoking, in addition, the intermediate product of the Maillard reaction is capable of generating a certain type of flavour in a targeted manner under the catalytic action of a solid acid.
