Abstract

The invention relates to a bacterial culture apparatus and a method for testing the antibacterial performance of snus. The apparatus comprises a plurality of independent box bodies, wherein a turntable is arranged in each box body, the turntable is provided with a plurality of fixed grooves for placing culture dishes, a temperature control unit and a gas exchanging unit are arranged in the box body, a rotator is arranged in the culture dish, and the bacterial culture apparatus is also provided with a controller which is connected with the temperature control unit and the gas exchanging unit inthe box body; and the to-be-tested snus and bacteria are cultured in the box body, so that the antibacterial performance of the snus can be determined. Compared with the prior art, the antibacterialperformance of the snus of the same batch can be tested by virtue of the apparatus of the invention, and the test efficiency is high; moreover, the temperature control unit and the gas exchanging unitare automatically controlled by virtue of the controller, so that the labor intensity is small; and meanwhile, the antibacterial performance of the snus can be quantitatively and qualitatively tested, and a test result is more complete.

Description

technical field [0001] The invention relates to the technical field of detection and authentication, in particular to a bacterial culture device and a method for testing the antibacterial performance of snus. Background technique [0002] Smokeless cigarettes refer to cigarette substitute products that do not have combustion smoke entering the mouth during smoking. Its main forms include chewing tobacco, snus, snuff, chewing gum, and battery-driven electronic cigarettes, or heat generated by combustion, heat conduction, and atomization. A category of mist steam such as tobacco products; smokeless cigarettes have the characteristics of no burning tobacco and related products, no smoke, and controllable chemical components. They are safer than ordinary cigarettes and easy to carry. The demand for cigarettes is also a way of cigarette consumption that shows individuality. [0003] Snus plays an important role in smokeless cigarettes and is a smokeless tobacco product originati...
