Problems solved by technology

The results of research on tobacco leaf harvesting methods all show that the traditional harvesting method of picking one mature leaf leaves only 2-3 tobacco leaves on the tobacco plant at the last harvest, which cannot develop and mature normally, resulting in the maturity of the upper tobacco leaves. Not enough, lower quality, less usable

Embodiment 1

[0026] Tobacco leaves with high nicotine content are strong, and high starch content will affect the taste of cigarettes.

[0027] Take 100 freshly picked upper tobacco leaves, cut each tobacco leaf along the side of the main vein, the tobacco leaves without the main vein are used as the control, and the tobacco leaves with the main vein are used for the experimental treatment. The control sample was placed in an oven at 40°C to dry, and the nicotine content and starch content of the tobacco leaf samples were determined. Soak the main vein of the tobacco leaf sample used for the test in 0.5-10cm of water, and place it for 24 hours at 35°C and a relative humidity of 85%. After the test is completed, remove the main vein of the tobacco leaf sample, and then place the tobacco leaf sample at 40°C After drying in an oven, the nicotine content and starch content of the tobacco leaf samples were determined. The test results showed that the starch content of the control sample was 8....

Embodiment 2

[0029] Tobacco leaves with high nicotine content are strong, and high starch content will affect the taste of cigarettes.

[0030]Take 100 freshly picked upper tobacco leaves, cut each tobacco leaf along the side of the main vein, the tobacco leaves without the main vein are used as the control, and the tobacco leaves with the main vein are used for the experimental treatment. The control sample was placed in an oven at 40°C to dry, and the nicotine content and starch content of the tobacco leaf samples were determined. Soak the main veins of the tobacco leaf samples used for the test in 0.5-10cm of water, place them for 72 hours at 20°C and a relative humidity of 60%. ℃ in an oven to determine the nicotine content and starch content of the tobacco leaf samples. The test results showed that the starch content of the control sample was 8.23%, and the nicotine content was 3.82%; the starch content of the test sample was 2.36%, and the nicotine content was 2.88%. The starch and...

Embodiment 3

[0032] Amino acids can undergo continuous Maillard reaction with reducing sugars in the process of tobacco leaf preparation and alcoholization, and produce compounds with characteristic aromas such as sweetness, toasted aroma, popcorn aroma, nutty aroma, and cheese aroma, which have a greater impact on the quality of tobacco leaves. big impact.

[0033] Take 100 freshly picked upper tobacco leaves, cut each tobacco leaf along the side of the main vein, the tobacco leaves without the main vein are used as the control, and the tobacco leaves with the main vein are used for the experimental treatment. Observe and record the color of the tobacco leaves of the control sample, then place the control sample in an oven at 40°C to dry, and measure the lysine content of the tobacco leaf sample. Prepare 0.01% lysine aqueous solution, soak the main vein of the tobacco leaf sample used in the test in the lysine aqueous solution for 0.5-10cm, and place it for 72h at 20°C and 60% relative hu...

Abstract

The invention relates to a tobacco leaf concocting method for improving the quality of tobacco leaves through soaking veins, and belongs to the field of raw materials of tobacco leaves. The invention discloses a new tobacco leaf concocting technique for changing the chemical component composition of the tobacco leaves after the tobacco leaves are picked and before the tobacco leaves are baked and aired. According to defects existing in the respects of maturity, the chemical components and the sense quality of fresh picked tobacco leaves, an appropriate tobacco additive is selected and compounded into an aqueous solution for soaking the veins of the tobacco leaves; the fresh picked tobacco leaves are taken, the main veins at the basal parts of the tobacco leaves are soaked into water or the aqueous solution by 0.5-10 cm, then the soaking state is kept for 6-72 hours under the condition of the temperature of 20-35 DEG C and the environment humidity of 50-85%, exogenous substances are input into the main veins by a vein soaking method, and the substances of the tobacco leaves are promoted to transform and accumulate, so that the quality of the tobacco leaves is improved.

Description

technical field [0001] The invention relates to a method for preparing tobacco leaves, in particular to a method for preparing tobacco leaves by soaking leaf veins to improve the quality of tobacco leaves, and belongs to the field of tobacco processing. technical background [0002] Tobacco leaf raw materials are the foundation of the cigarette industry. The chemical composition and coordination of tobacco leaves determine the quality of tobacco leaves, and also determine the smoke characteristics of tobacco leaves and their products to a large extent. The chemical composition of tobacco leaves is very complex, and can be summarized into the following three categories: 1. Non-nitrogenous compounds, including monosaccharides, disaccharides, starch, organic acids, petroleum ether extracts, terpenes, polyphenols, fibers Factors such as pectin and pectin. Within a certain range, the higher the sugar content, the better the quality of the tobacco leaves. Starch affects the comb...
