Problems solved by technology

In addition, the smell caused by mildew will remain in the cigarette pack, causing the tobacco leaves that are not moldy to also have a musty smell, seriously affecting the quality of the entire batch of tobacco leaves
In addition, other raw materials of cigarettes, such as filter paper, adhesives, cigarette paper, etc., will also be eroded by microorganisms, resulting in a decrease in their elasticity and strength

Abstract

The invention discloses a natamycin complex formulation for controlling mildew of redried tobacco strips, and a control method by using the natamycin complex formulation. The formulation consists of the following components in percentage by weight: 10-20% of natamycin, 10-20% of lactose, 0.5-2.5% of Tween 20, 2-5% of glycerin, 0.5-2.5% of white carbon black, 0.05-0.3% of xanthan gum, 0.2-0.6% of methyl silicon oil and the balance of water. The control method of the invention comprises the following steps: during a process of redrying, diluting the natamycin complex formulation for controlling mildew of the redried tobacco strips with water after threshing tobacco leaves and drying and before packing, and uniformly spraying onto the tobacco leaves, wherein the amount of spraying is 0.3-0.5% of total weight of the tobacco leaves, so that the concentration of the active ingredient natamycin in the tobacco leaves is 5-15ppm. According to the control method of the invention, after 70816 piculs of tobacco leaves for the redried tobacco strips are treated by the natamycin complex formulation for controlling mildew of the redried tobacco strips of the invention, the treated tobacco leaves are not found to mildew during storage, and do not change in sensory quality.

Description

Technical field: [0001] The invention relates to an antifungal agent and a control method thereof, in particular to a natamycin compound formula for preventing and curing the mildew of rebaked sheets and the control method thereof. Background technique: [0002] Tobacco leaves are highly hygroscopic and prone to mildew during storage. Due to the growth of mold, the dissolved matter in tobacco leaves is decomposed, and the normal tissue structure is destroyed. The appearance is darkened, the original aroma disappears, an unpleasant musty odor is emitted, the irritation increases, the taste is bitter, and the toughness and elasticity of cut tobacco disappear. In addition, the smell produced by mildew will remain in the cigarette pack, causing mildewed tobacco leaves to also produce musty smell, seriously affecting the quality of the entire batch of tobacco leaves. In addition, other raw materials of cigarettes, such as filter paper, adhesives, cigarette paper, etc., will als...
