Problems solved by technology

The temperature control and humidity control method has high requirements on the warehouse, requires a large number of temperature and humidity control equipment, and consumes a lot of electric energy. In actual production, it is difficult to achieve the desired effect; the amount of spraying antifungal agent is large, and it is difficult to spray evenly and Comprehensive, so the effect is limited. In addition, cigarettes or tobacco leaves processed into cigarettes after adding antifungal agents will produce harmful gases due to high temperature cracking when burning and smoking, which will affect human health, and the residue of antifungal agents will also pollute the environment; Oxygen can effectivel

Example Embodiment

[0016] Example 1

[0017] Randomly take 300kg of first-cured tobacco leaves, pack each 30kg into a box, a total of 10 boxes, seal and pack them in corrugated boxes with plastic film lining, and then use electron beams at doses of 0kGy, 4kGy, 6kGy, 8kGy, and 10kGy for irradiation treatment , 2 boxes for each treatment, stored in a warehouse with a temperature of 25°C-30°C and a relative humidity of 75%-95% after irradiation, and regularly sampled for microbial testing. The test results are shown in Table 1. After each sampling, the packaging is still sealed Best stored under original conditions.

Example Embodiment

[0018] Example 2

[0019] Randomly take 400kg of re-cured tobacco leaves, pack each 40kg into a box, a total of 10 boxes, seal and pack them in corrugated boxes with plastic film lining, and then use electron beams of 0kGy, 4kGy, 6kGy, 8kGy, and 10kGy for irradiation treatment , 2 boxes for each treatment, stored in a warehouse with a temperature of 25°C-30°C and a relative humidity of 75%-95% after irradiation, and regularly sampled for microbial testing. The test results are shown in Table 1. After each sampling, the packaging is still sealed Best stored under original conditions.

Example Embodiment

[0020] Example 3

[0021] 10 boxes of cigarettes of the same brand that had just been purchased from the cigarette factory were irradiated with X-rays of 0kGy, 4kGy, 6kGy, 8kGy, and 10kGy respectively. ℃, relative humidity of 75%-95% of the warehouse, regular sampling for microbial testing, the test results are shown in Table 1, after each sampling, still sealed and packaged for storage under the original conditions.

[0023]

[0024] Determination method of mold in Table 1: according to GB / T4789.15 "Food Hygiene Microbiological Examination of Mold and Yeast Count".

[0025] As can be seen from Table 1, the radiation-proof mildew-proof method for tobacco leaves and products thereof of the present invention has a remarkable anti-mold effect by killing enzymes. Compared with unirradiated samples, 4kGy-10kGy dose irradiation treatment can reduce the number of molds by orders of magnitude, 8kGy-10kGy dose irradiati...

Abstract

The invention relates to a tobacco leaf and a green mould proof method of products thereof, which is characterized in that after raw tobacco leaves are packed by a corrugated case provided with a plastic inner liner, or packed and sealed cigarette finished product packing boxes are directly irradiated by ray with the dosage of 4kGy-10kGy, so that the aims of killing and preventing mould can be achieved. The invention has the advantages that electron accelerator irradiation technology is adopted and is easy to combine with the existing tobacco processing technique, and irradiation can be taken as a working procedure in the process flow of the tobacco processing technique; an electron accelerator is directly installed in a flow line of tobacco processing, so that automation is easy to realize; the ray generated by the electron accelerator has higher energy and can penetrate the cigarette boxes, so as to rapidly and thoroughly kill the mould in the tobacco leaves and the products thereof with high efficiency for once, reduce mildew loss, and lower the administrative expense on a tobacco barn; furthermore, the ray can kill pests in tobacco storage, accelerate the alcoholization of the tobacco leaves, and improve the suck quality of the tobacco leaves, so that the invention has practicability; in addition, the invention opens up a new path for preventing mould of the tobacco, thus having considerable market prospect.

Description

technical field [0001] The invention relates to a method for killing and preventing tobacco mold, in particular to a green anti-mold method for tobacco leaves and products thereof. Background technique [0002] Tobacco leaves must go through a warehousing process before being processed into cigarettes. The purpose has two aspects: one is to store enough raw materials for the tobacco factory; the other is to carry out natural aging of tobacco leaves. After the tobacco leaves are harvested and baked, due to the presence of a large amount of nitrogen-containing compounds, free bases, volatile acids, and gas phase or particle phase substances that are incompatible with the smoke, the tobacco leaves have a serious green smell and pungent taste, and the smoking quality is poor. Cigarette production can only be carried out after alcoholization. The process of natural alcoholization of tobacco leaves is slow and generally takes 1-3 years. [0003] The long-term storage period of t...
