Problems solved by technology

[0009] From the above literature, it can be seen that many tobacco workers are trying to solve the problem of poor quality and low utilization rate of upper tobacco through various links such as baking and modulation, storage and aging, and shredding processing. Although these methods have certain effects, However, the aforementioned patent method only uses additional substances or high-temperature treatment to cover up or modify the quality defects of unsuitable tobacco leaves that have been put into storage, and does not intervene early in the tobacco leaf production process, resulting in limited effects or limited realization capabilities (equipment, substance use license); Cheng Yuyuan , Yan Keyu and other scholars took into account the characteristics of the chemical composition of the upper smoke and involved adding sugar or acid to the upper smoke to improve the balance of chemical components, but did not consider adding sugar and acid at the same time, and the selected sucrose was in the pyrolysis process. It is not suitable for direct addition to tobacco; the license of boric acid in current cigarette production is limited

Embodiment 1

[0035] Preparation of invert sugar: Weigh 15 grams of sucrose, add 18 grams of water, 0.4 grams of edible phosphoric acid, and stir continuously at 120°C until it turns brown.

[0036] Preparation of acidic aqueous solution containing invert sugar: Take the above-mentioned invert sugar hot solution, add 0.6 g of edible phosphoric acid, dilute to 200 g with water, stir well and filter for later use. At this time, the sugar concentration of the acidic aqueous solution is about 7.5%, and the pH value is about 1.9.

[0037] How to use it on the upper tobacco leaves: In the production area of ​​Zhangjiajie, Hunan, 40 mature upper tobacco leaves are harvested normally, and the above-mentioned prepared acidic aqueous solution containing invert sugar is evenly sprayed on the front and back of the above-mentioned just-harvested tobacco leaves with a small spray device Both sides are then installed in the same tobacco oven as the control, and are baked according to conventional technique...

Embodiment 2

[0045] Preparation of invert sugar: Weigh 300 grams of sucrose, add 360 grams of water, 8 grams of edible phosphoric acid, and stir continuously at 120°C until it turns brown.

[0046] Preparation of an acidic aqueous solution containing invert sugar: take the above invert sugar hot solution, add 12 grams of edible phosphoric acid, dilute to 4000 grams with water, stir well and filter for later use. At this time, the sugar concentration of the acidic aqueous solution is about 7.5%, and the pH value is about 1.9.

[0047] How to use it on the upper part of flue-cured tobacco: Spray the above-mentioned acidic aqueous solution containing invert sugar evenly with an agricultural sprayer on the upper part of 120 trees in the Zhangjiajie production area of ​​Hunan Province with only 6-7 upper leaves left two days before ripening. The front and back sides of the tobacco leaves are harvested two days later, and put into the same barn as the control at the same time, and are roasted an...

Embodiment 3

[0056] 1. Material preparation

[0057] Preparation of invert sugar: Weigh 90 grams of sucrose, add 108 grams of water, 2.4 grams of edible phosphoric acid, and stir continuously at 120°C until it turns brown.

[0058] Preparation of an acidic aqueous solution containing invert sugar: take the hot invert sugar solution, add 3.6 grams of edible phosphoric acid, dilute to 1200 g with water, stir well and filter for later use.

[0059] Other reagents: glacial acetic acid (acetic acid), glucose, fructose, and xylose were all purchased analytically pure.

[0060] 2. Method

[0061] Using the single factor test method, in the same flue-cured tobacco field in Zhangjiajie, Hunan Province (the total nitrogen application rate of the tobacco field is 8.5kg, the ratio of nitrogen, phosphorus and potassium is 1:1.2:2.6, and the row-to-plant spacing is 1.1m×0.5m), according to Table 3 For the treatment conditions, 40 mature flue-cured tobacco leaves with only the upper 6 leaves were selec...

Abstract

The invention discloses an annexing agent and method for improving upper flue-cured tobacco leaf quality in the tobacco leaf production link. The annexing agent is an acid aqueous solution containing monosaccharide; in the flue-cured tobacco growing stage, after tobacco leaves in the middle are harvested and before the tobacco leaves at the upper portion are harvested, the annexing agent is added on the surfaces of the tobacco leaves at the upper portion, and picking and baking are carried out according to a normal method. The method is simple in operation and low in cost; after the upper flue-cured tobacco leaves are processed in the method, the appearance quality of the upper flue-cured tobacco leaves is not obviously changed compared with that of non-processed upper flue-cured tobacco leaves, but the internal sensory quality is obviously improved; the annexing agent is mainly characterized in that coke is sweet, note is displayed, the rough frangrance is improved, scorched miscellaneous qi is reduced, smoke is more pure, mild and fine, the impact feeling of alkaloid to the laryngopharyngeal recess is reduced, the remaining taste is comfortable and clean, and the availability is obviously improved.

Description

technical field [0001] The invention relates to an additive and a method for improving the quality of upper tobacco leaves of flue-cured tobacco in the production process of tobacco leaves, belonging to the field of tobacco. Background technique [0002] Due to the fact that most of the upper tobacco leaves of flue-cured tobacco in my country have relatively thick leaves, tight tissue structure, high nicotine content, low reducing sugar and sugar-alkaline ratio, uncoordinated internal chemical components, rough smoke, excessive strength, strong physiological impact, Quality defects such as nitrogen-containing miscellaneous gases, prominent alkaline odor, and obvious dryness, the upper tobacco leaves of flue-cured tobacco have not been widely used in cigarette products in a timely manner. Over the years, cigarette industrial enterprises have accumulated a considerable amount of upper unsuitable tobacco leaf raw materials. [0003] The reality that the upper part of flue-cured ...
