Embodiment 1

[0017] Polyphenol oxidase inhibitor solution: use tap water or distilled water as a solvent to prepare a solution containing 0.5% (mass ratio) of kojic acid and 2.0% (mass ratio) of ascorbate.

[0018] Tobacco leaf treatment method: put the solution in a rectangular water tank, immerse the harvested fresh tobacco leaves in the water tank for 5-8 minutes, take it out, drain the open water, let it dry for 2-3 hours, then transfer it to the barn for conventional baking and extraordinary Regular baking. The control was soaked in clean water, and the follow-up treatment was consistent with that of the treatment group. Conventional baking is carried out in the farmhouse, using a standardized 5-stage baking mode. The unconventional baking was carried out in the laboratory with the YHSJ-1 baking test machine produced by Kunming Jiaye Technology Co., Ltd. Compared with conventional baking conditions, the late yellowing period is extended for 24 hours, and other process conditions rem...

Embodiment 2

[0020] Polyphenol oxidase inhibitor solution: use tap water or distilled water as a solvent to prepare a solution containing 0.2% (mass ratio) of ferulic acid and 2.0% (mass ratio) of ascorbate.

[0021] Tobacco leaf processing method is the same as embodiment 1.

Embodiment 3

[0023] Polyphenol oxidase inhibitor solution: use tap water or distilled water as a solvent to prepare a solution containing kojic acid at a concentration of 0.05% (mass ratio) and ascorbate at a concentration of 2.0% (mass ratio).

[0024] Tobacco leaf processing method is the same as embodiment 1.

Abstract

The invention discloses a method for preventing a browning reaction caused by improper tobacco leaf curing, and belongs to the technical field of cigarette making. The method comprises the following steps: picking tobacco leaves, soaking and curing, wherein the soaking step comprises the following sub-steps: flatly laying the tobacco leaves in a rectangular water tank filled up with a polyphenol oxidase inhibitor solution, and soaking for 5-8 minutes, so that the activity of the polyphenol oxidase (PPO) can be inhibited, the browning reaction can be reduced, and a tobacco leaf curing effect can be improved. A polyphenol oxidase inhibitor is one or more of kojic acid, ferulic acid and ascorbate, and also can contain other organic acids. By applying kojic acid, ferulic acid, ascorbate and other organic acid combinations, the browning reaction of the tobacco leaves can be effectively inhibited and the proportion of bright yellow tobacco leaves can be increased to 6%-15%.

Description

technical field [0001] The invention relates to the technical field of cigarette manufacture, in particular to a method for preventing browning reaction caused by improper preparation of tobacco leaves. Background technique [0002] Phenolic substances play a decisive role in the color and luster of tobacco leaves, and are also an important source material basis for the flavor and aroma of flue-cured tobacco products. Enzymatic browning (browning reaction) with phenolic substances as substrates is the key factor leading to the deterioration of the color of tobacco leaves after conditioning. During the conditioning process, the cell wall of tobacco leaves is broken, resulting in the combination of phenolic substances and polyphenol oxidase, resulting in enzymatic browning, resulting in the color of tobacco leaves changing from yellow to orange or brown in varying degrees; in addition, the oxidation products of polyphenols It can also undergo enzymatic browning reaction with ...
