A regulator for enhancing the burnt-sweet flavor of tobacco leaves and its method for treating tobacco

Abstract

The invention discloses a regulating agent capable of enhancing the sweet aroma of tobacco leaves. The regulating agent is prepared from the following raw materials in parts by weight: 2.00-3.32 parts of L-aspartic acid, 2.32-3.88 parts of L-histidine, 0.46-0.69 part of L-proline, 0.52-0.77 part of L-isoleucine, 2.13-3.46 parts of potassium hydroxide, and 2.50-3.50 parts of sucrose ester. The invention further provides a method for processing the tobacco leaves by adopting the regulating agent capable of enhancing the sweet aroma of the tobacco leaves. The method comprises the steps of preparation of regulating agent stock solution, pretreatment on the tobacco leaves, baking of the tobacco leaves, and the like. According to the method provided by the invention, after L-aspartic acid, L-histidine, L-proline and L-isoleucine have cation exchange reaction with potassium hydroxide, amino acid potassium salt is formed, and the solubility of the amino acid potassium salt is relatively high, so that the problem that the solubility of amino acid is relatively low is effectively improved, further, the absorption by the tobacco leaves is facilitated, the occurrence of Maillard reaction is promoted, the number of the products of the Maillard reaction greatly increases, therefore, the sweet aroma of the tobacco leaves is effectively enhanced, and the fluctuation of product quality caused by environmental deviation is reduced.

Description

technical field [0001] The invention relates to a tobacco additive, in particular to a regulator for enhancing the coke sweet flavor of tobacco leaves. Background technique [0002] The coke sweet aroma of tobacco leaves is known as "the crown of the aroma", which is a common feature of the best quality tobacco leaves in the world. However, the most prominent category of suitable areas for the coke sweetness of tobacco leaves only accounts for about 20% of the total area of ​​tobacco fields, which cannot meet the urgent needs of cigarette industrial enterprises for high-quality coke sweet tobacco leaf raw materials. In addition, the unstable quality of scorched cigarette leaves due to climate differences between years is also a limiting factor restricting the production of scorched cigarette leaves. [0003] At present, in the production of cigarettes, the burnt sweetness is mainly improved by directly adding a flavouring agent with burnt sweetness to the cut tobacco. Altho...

However, the most prominent type of suitable area for the burnt-sweet aroma of tobacco leaves only accounts for about 20% of the total area of ​​the tobacco field, which cannot meet the urgent needs of cigarette industry enterprises for high-quality burnt-sweet cigarette leaf raw materials

In addition, the unstable quality of tobacco leaves due to climate differences between years is also a limiting factor restricting the production of burnt sweet tobacco leaves

[0003] At present, in the production of cigarettes, the flavor enhancer with burnt-sweet flavor is mainly added directly to shredded tobacco to improve the burnt-sweetness. Although this method can enhance the flavor, the flavor produced is far from the natural flavor of flue-cured tobacco. unsatisfactory
