Embodiment 1

[0014] Taking the flue-cured tobacco variety Yunyan 87 as the implementation object, the upper tobacco leaves with stems were harvested, woven into stems, and left to stand for 6 hours, and then a groove was dug at the top of the inverted tobacco stem, and potassium ion concentration of 1mol / L was injected into the groove. Potassium sulfate solution 2 times, inject 6ml each time, let stand for 2 hours after each injection, and finally hang it into the baking room for baking.

[0015] The purpose of standing for 6 hours is to fully wilt the leaves, that is, when the tobacco leaves are placed in dry air, the water in them will gradually lose into the air, which will make the osmotic pressure of the water in the leaves much higher than the osmotic pressure of the flue-cured tobacco stems , laying the foundation for the next transfer of potassium ions and water. Among them, the standard for harvesting the upper tobacco leaves with stems is that the main veins of the upper leaves a...

Embodiment 2

[0020] A method for increasing the potassium content of tobacco leaves. The upper part of flue-cured tobacco leaves with stems are harvested, woven into stems, left to stand for 8 hours, and then a groove is dug at the top of the inverted tobacco stem, and the concentration of potassium ions is injected into the groove at a concentration of 1.4mol / L of potassium carbonate solution 1 time, inject 6ml, let it stand for 4 hours after injection, and finally hang it into the baking room for baking.

Embodiment 3

[0022] A method for increasing the potassium content of flue-cured tobacco. The upper part of flue-cured tobacco leaves with stems are harvested, woven into stems, left to stand for 4 hours, and then a groove is dug at the top of the inverted tobacco stem, and the concentration of potassium ions is injected into the groove at a concentration of 0.8mol / L of potassium dihydrogen phosphate solution 4 times, inject 4ml each time, let it stand for 2 hours after each injection, and finally hang it into the baking room for baking.

[0023] Collect 2 kg of cured tobacco leaves of Examples 1-3 respectively as samples for laboratory analysis and sensory evaluation.

[0024] Quality evaluation of cured tobacco leaves: See Table 1-3 for the results.

Abstract

The invention discloses a method for improving content of potassium in tobacco leaves. The method comprises the following steps of: harvesting upper tobacco leaves with stems, knitting the upper tobacco leaves into rods, standing for 4-8 hours, digging a groove at the top end of inverted tobacco stems, injecting potassium salt solution with potassium ion concentration being 0.5-2mol / L into the groove at 1-4 times, injecting 4-6ml of the potassium salt solution at each time, standing for 2-4 hours after injection at each time, and finally hanging the tobacco leaves into a curing room for curing. The method for improving the content of the potassium in the tobacco leaves has the advantages that the content of the potassium in the tobacco leaves can be greatly improved, the commodity grade of the tobacco leaves which are treatment by adopting the method is obviously improved, the content of internal chemical components is more suitable and harmonious, the combustibility of the tobacco leaves is improved, the form of smoke is improved and the smoking quality is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation and preparation, and in particular relates to a method for increasing the potassium content of tobacco leaves. Background technique [0002] Potassium is an essential nutrient element for all plants, and it is one of the most important quality elements in tobacco. The abundance of potassium in tobacco leaves is an important basis for judging the quality of tobacco leaves. The level of potassium content in tobacco leaves directly affects the combustibility, taste, and safety of cigarette products. Tobacco leaves with high potassium content have a dark orange appearance, more oil, better elasticity, softer, more suitable and coordinated internal chemical components, stronger combustibility, aroma quality, aroma quality, taste, aftertaste, comfort, etc. Taste index performance is better; Tobacco leaves with low potassium content have lower combustibility, lower suitability of chemical co...
