Embodiment 1

[0017] 50 grams of natamycin accounting for 0.005% by weight and 200 grams of potassium citrate accounting for 0.02% by weight were dissolved in 999.75 kg of water and stirred evenly to obtain the required antifungal agent. Use a sprayer to evenly spray the above solution to the fresh tobacco leaves that have been braided and ready to enter the barn. After the kang is installed, the conventional three-step baking process is used for initial baking, so that the tobacco leaves can obtain resistance to mildew microorganisms. sex.

Embodiment 2

[0019] 50 grams of natamycin accounting for 0.005% by weight and 200 grams of potassium citrate accounting for 0.02% by weight were dissolved in 999.75 kg of water and stirred evenly to obtain the required antifungal agent. Soak the fresh tobacco leaves that have been braided and ready to enter the barn in the antifungal agent for 10 minutes. After draining, put them on the kang for initial baking according to the conventional three-step baking process, so that the tobacco leaves can acquire resistance to mildew microorganisms.

Embodiment 3

[0021] Dissolve 250 grams of 0.025% by weight of natamycin and 400 grams of 0.04% by weight of potassium citrate in 999.35 kg of water, and stir evenly to obtain the desired antifungal agent. Use a sprayer to evenly spray the above solution to the fresh tobacco leaves that have been braided and ready to enter the barn. After the kang is installed, the conventional three-step baking process is used for initial baking, so that the tobacco leaves can obtain resistance to mildew microorganisms. sex.

Abstract

The invention discloses flue-cured tobacco mildew preventive. The flue-cured tobacco mildew preventive is prepared from 0.002%-0.2% of natamycin, 0.02%-0.08% of potassium citrate and the balance of water which are uniformly mixed. The flue-cured tobacco mildew preventive is uniformly added to fresh tobacco leaves in a preliminary baking stage by adopting a spraying or soaking method, and the fresh tobacco leaves are preliminarily baked according to a conventional three-step baking technology after being loaded, so that the tobacco leaves has resistance to mildew microorganisms. Experiments prove that the mildew preventive disclosed by the invention has no influence on the tobacco leaves and is non-toxic and non-irritant for human bodies. The mildew preventive the advantages of being simple in technology and low in operating cost, enabling the resistance to the mildew microorganisms of the tobacco leaves to run through the whole process from tobacco leaf braking to storage, preventing the tobacco leaves from mildewing in the processes of preliminary baking, classification, transportation and storage and having good popularization and application value and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to an antifungal agent for flue-cured tobacco that can continuously exert its effectiveness in the whole process of tobacco leaf curing, transportation and storage. Background technique [0002] Mildew is a devastating damage caused by mold, which widely occurs in many fields such as industry and agriculture. Tobacco leaves go through a series of processes such as initial roasting, grading, purchasing, and packaging, and a large number of microorganisms are attached to the surface and inside. Because tobacco leaves are highly hygroscopic and contain various nutrients required for microbial growth, once the conditions are suitable, tobacco leaves will be stored during storage. It is very easy to breed various microorganisms, decompose the organic substances in the tobacco leaves, and cause them to deteriorate and rot, thus causing symptoms such as discolorati...
