Method for determining smelly substances in paper-making reconstituted tobacco white water

Abstract

The invention belongs to the technical field of tobacco production, and concretely relates to a method for determining smelly substances in paper-making reconstituted tobacco white water. The method comprises the following steps: collecting a white water sample by using a specific white water smelly substance collection device, and analyzing and detecting adsorbed substances through thermal desorption-gas chromatography-mass spectrometry; and judging that the white water is deteriorated and replacing or treating the white water when it is detected that the content of any one of dimethyl disulfide, N,N-dimethylformamide and dimethyl trisulfide in the white water exceeds a limit value. The method for determining smelly substances in the white water is sensitive and reliable, and the detection result is objective and is not affected by people's subjective feelings, so the judgment result of the quality of the white water is objective, and a good basic guarantee is provided for guiding theproduction of reconstructed tobacco leaves and ensuring the tobacco quality, thereby the method has good promotion and application meaning in the cigarette production field.

Description

technical field [0001] The invention belongs to the technical field of tobacco production, and in particular relates to a method for measuring odorous substances in white water of reconstituted tobacco leaves by a papermaking method. Background technique [0002] Due to its many advantages, papermaking reconstituted tobacco leaves are increasingly favored by tobacco companies. However, the current domestic papermaking reconstituted tobacco technology level, technical equipment support and product quality level are still obviously insufficient, and the water consumption and energy consumption are obviously high, which affects the application ratio and application grade of products in Chinese cigarettes to a certain extent. The improvement of production technology is an imminent demand. [0003] In the production process of reconstituted tobacco leaves by the papermaking method, the pulp concentration before the pulp on the water screen is about 1%, and after the headbox to t...

Problems solved by technology

[0004] At present, the quality control of white water mainly depends on the artificial sense of smell to judge whether it is recycled or not. Due to the different olfactory sensitivity and state of each person, the judgment standard for the odor of white water will also deviate. In order to ensure the quality, the white water that has been circulated for one or two days must be advanced in advance emissions, which in turn creates unnecessary waste
