Embodiment 1

[0013] Take the single-material tobacco leaves Jiaxian Zhongyan 100B2F and Jiaxian Zhongyan 100C2F, and divide them into 10 sections from the tip to the base of the leaf, and number them from the tip to the base of the leaf as 1-10 to accurately measure the Jiaxian Zhongyan See Table 1 for the determination results of the petroleum ether extract content in ten regions of 100 B2F and C2F tobacco leaves.

[0014] Table 1 The content of petroleum ether extracts in different regions

[0015]

[0016] The average petroleum ether extract content of tobacco leaves of Jiaxian China Tobacco 100B2F tobacco leaves (3.38) was lower than that of Jiaxian China Tobacco 100C2F tobacco leaves (3.92), and the HN-1, HN -2, HN-3, HN-4, HN-5, the average petroleum ether extract content (4.09) was higher than that of Jiaxian Zhongyan 100C2F whole tobacco leaves. The No. 1~5 sections of Jiaxian China Tobacco 100B2F are divided into the first section, the No. 6-7 sections are divided into the s...

Embodiment 2

[0018] Take single-material tobacco leaves Lushiyun 87C3F and Kunmingyun 87C3F, divide them into 10 sections from the tip to the leaf base, and number them from tip to leaf base sequentially as 1-10, and accurately measure Lushiyun 87C3F and Kunmingyun respectively. The content of petroleum ether extract in ten areas of cut 87C3F tobacco leaves is shown in Table 2.

[0019] Table 2 The content of petroleum ether extracts in different regions

[0020]

[0021] The average petroleum ether extract content of the whole leaf of Lushiyun 87C3F tobacco leaves (4.11) was lower than that of Kunming Yun 87C3F whole tobacco leaves (4.52), and HN-1 and HN-2 of Lushiyun 87C3F after cutting , HN-3, HN-4, HN-5 five areas of petroleum ether extract content mean (5.01) was higher than the Kunming Yun 87C3F whole tobacco leaf petroleum ether extract mean. The No. 1~5 sections of Lushiyun 87C3F tobacco leaves were divided into the first section, the No. 6-7 sections were divided into the s...

Abstract

The invention belongs to the technical field of tobacco quality control, and in particular relates to a method for cutting Luzhou-flavor tobacco leaves with the content of petroleum ether extract as an evaluation index. According to the cutting method, the tobacco leaves are divided into three sections according to the content of petroleum ether extract in the tobacco leaves, among which the first section tobacco leaves, the second section tobacco leaves and the third section tobacco leaves are respectively from the tip to the leaf base, and the first section The length of the tobacco leaves accounts for 45-55% of the total length of the tobacco leaves, the length of the second section of the tobacco leaves accounts for 15-25% of the total length of the tobacco leaves, and the length of the third section of the tobacco leaves accounts for 25-35% of the total length of the tobacco leaves. On this basis, the present invention realizes rational utilization of the raw material of Luzhou-flavor tobacco leaf, highlights the quality characteristics of different locations of the leaf, and improves the overall utilization efficiency of the raw material of tobacco leaf.

Description

Technical field [0001] The present invention is the field of tobacco quality control technology. It involves a tobacco leaf division method, which specifically involves a separate method of fragrant tobacco leaves based on the content of petroleum ether extract. Background technique [0002] Petroleum ether extracts of tobacco leaves are based on petroleum ether as a solvent. Mixture obtained after extraction of tobacco leaf samples mainly include volatile oil, resin, oil, fatty acids, wax, lipids, alcohol, pigment, etc.The content of smoke leaf petroleum ether extract is related to the aroma of tobacco. During the maturity, modulation, and aging process of petroleum ether extracts, it has been decomposed and transformed to form fragrances.One of the important indicators of the quality and aroma of tobacco leaves.Different regions, climate conditions, cultivation conditions, varieties, and baking conditions have a certain effect on the content of petroleum ether extracts.However,...
