Method and device of detecting mildewing performance of cigarette microorganisms

Abstract

The invention relates to a method and a device of detecting mildewing performance of cigarette microorganisms. The method of detecting the mildewing performance of the cigarette microorganisms comprises the steps of providing cut tobacco; adding to-be-detected microorganisms to the cut tobacco; putting the cut tobacco including the to-be-detected microorganisms in an accelerated mildewing environment; and after preset time, calculating the mildewing performance of the to-be-detected microorganisms based on the mildewing degree of the cut tobacco. The detecting method has simple steps, is convenient to operate, can detect the mildewing performance of the to-be-detected microorganisms rapidly, accurately and reliably, can provide basis for mildewing control, can reduce mildewing risks of cigarettes and can improve the cigarette quality.

Description

technical field [0001] The invention relates to the technical field of tobacco, in particular to a method and a detection device for detecting the mold-causing microorganisms of cigarettes. Background technique [0002] Mildew of cigarettes refers to the mildew and deterioration of cigarettes caused by mold infection. The moisture content of finished cigarettes is about 12%, and mildew is not easy to occur. However, when the cigarette package is damaged and the storage environment is poor, the cigarette will produce mildew. Cigarette mildew will not only have a huge impact on the quality of cigarettes such as fragrance and appearance, reduce the value of finished products, but also have a considerable impact on the economic benefits of enterprises. Moreover, cigarettes are the final product in the production of cigarettes that are in direct contact with consumers. Mildewed cigarettes will bring a greater sense of disgust to consumers. In the long run, mildewed cigarettes wi...

Problems solved by technology

[0004] At present, the existing methods for detecting the degree of mildew-causing microorganisms in cigarettes mainly include: ① sensory evaluation, when there are macular spots or black spots visible to the naked eye on the surface of the cigarette, and there is a relatively obvious musty smell when smoking, Judging that mildew has occurred in cigarettes, this method is greatly influenced by evaluators, and the results given by different evaluators may be different, and this method cannot quantitatively determine the degree of mildew in cigarettes; Different types of microorganisms and different cigarette samples lead to different mold-causing properties of moldy microorganisms, and there is no definite relationship between the number of moldy microorganisms and cigarette mildew; ③Chemical method, to determine the content of ergosterol in moldy tobacco The pre-treatment of the samples is more complicated, and there are higher requirements for the equipment conditions, and in some cigarettes with macular mildew, ergosterol was not detected, and the mildew test results were not accurate
