Embodiment 1

[0019] The weight percent content of each component of the flue-cured tobacco leaf roasting aroma enhancing agent is: 3.5% hydrogen peroxide, 3.5% acetic acid, 0.10% beta-methylpentanoic acid, 0.03% ethyl maltol and 92.87% water. According to the weight percentage content of the above components, the flue-cured tobacco leaf roasting flavoring agent is prepared. After preparation, the front and back sides of the mature and harvested tobacco leaves are evenly sprayed, and the spraying amount is 250g per hundred tobacco leaves. The test results are shown in Table 1. After the above treatment, the catalase activity in the tobacco leaves was higher than that of the control in the temperature range exceeding 60°C, and the petroleum ether extract content of the cured tobacco leaves increased by 0.71 percentage points; the sensory quality evaluation of the cured tobacco leaves was The aroma quality is increased from "medium" to "middle upper", the aroma amount is increased from "existe...

Embodiment 2

[0021] The weight percent content of each component of the flue-cured tobacco leaf roasting aroma enhancing agent is: 2.0% of hydrogen peroxide, 2.5% of acetic acid, 0.1% of β-methylpentanoic acid, 0.03% of ethyl maltol and 95.37% of water. According to the weight percentage of the above components, it is formulated into a flue-cured tobacco leaf roasting aroma enhancing agent. After preparation, it is evenly sprayed on the front and back of mature harvested tobacco leaves, and the spraying amount is 200g per hundred tobacco leaves. The test results are shown in Table 1. After the above treatment, the catalase activity in the tobacco leaves was higher than that of the control in the temperature range exceeding 60°C, and the petroleum ether extract content of the cured tobacco leaves increased by 0.49 percentage points; the sensory quality evaluation of the cured tobacco leaves was The aroma quality is increased from "medium" to "middle upper", the aroma amount is increased from...

Embodiment 3

[0023] The weight percent content of each component of the flue-cured tobacco leaf roasting aroma enhancing agent is: 3.0% hydrogen peroxide, 3.0% acetic acid, 0.1% 3-methylpentanoic acid, 0.03% ethyl maltol and 93.87% water. According to the weight percentage of the above components, it is formulated into a flue-cured tobacco leaf roasting aroma enhancing agent. After preparation, it is evenly sprayed on the front and back of mature harvested tobacco leaves, and the spraying amount is 220g per hundred tobacco leaves. The test results are shown in Table 1. After the above treatment, the catalase activity in the tobacco leaves was higher than that of the control in the temperature range exceeding 60°C, and the petroleum ether extract content of the cured tobacco leaves increased by 0.52 percentage points; the sensory quality evaluation of the cured tobacco leaves was Aroma quality increased from "medium" to "middle upper", aroma quantity increased from "less" to "existent", arom...

Abstract

A baking flavoring agent of fire-cured tobacco leaves is characterized in that the flavoring agent is made from the following components by weight percentages: 1%-5% of hydrogen peroxide, 0.05%-0.25% of beta-methyl pentanoic acid, 0.01%-0.05% of ethyl maltol, 1%-4% of acetic acid, and 90.70%-97.94% of water. The way for using the flavoring agent is as follows: after the tobacco leaves ripen and are picked, the flavoring agent is evenly sprayed on the front face and rear face of the tobacco leaves by a sprayer until the surfaces of the tobacco leaves become wet but not drop water; 200g-250g of the flavoring agent is used for every 100 tobacco leaves; after being sequentially arranged on rods, the tobacco leaves are put in a cool place for airing, and then put in a baking room for normal baking. Test data prove that application of the flavoring agent of the invention to the pre-baking treatment of the fire-cured tobacco leaves can greatly improve the content of a petroleum ether extract in the tobacco leaves, effectively promote the aroma quality, and obviously improve the aroma content and aroma concentration.

Description

technical field [0001] The present invention relates to the treatment of flue-cured tobacco leaves before baking, in particular to a roasting aroma enhancing agent for flue-cured tobacco leaves and its application. Aroma. Background technique [0002] During the curing process of tobacco leaves, there is a certain degree of correlation between the formation of tobacco aroma substances and the activity of catalase in tobacco leaves. Most of the degradation products of cembranes and carotenoids are aroma substances of tobacco leaves. This process requires the participation of oxygen. Catalase can catalyze the decomposition of hydrogen peroxide into water and oxygen, creating a favorable environment for the production of aroma substances. Favorable conditions. Experiments have shown that when the tobacco leaves exceed 60°C during the roasting process, the catalase will undergo heat denaturation, the activity will decrease, and the reaction speed will slow down, which will aff...
