A method for the determination of off-flavor substances in the white water of reconstituted tobacco leaves by papermaking

Abstract

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. The method uses a specific white water odor gas collection device to collect white water samples, and then uses thermal desorption-gas chromatography to analyze and detect the adsorbed substances; dimethyl disulfide, N,N-dimethyl When the content of any one of the three substances, methyl formamide or dimethyl trisulfide, exceeds the limit value, it can be considered that the white water has deteriorated and should be replaced or treated. The method for measuring odorous substances in white water proposed by the present invention is more sensitive and reliable, and the detection result is more objective, and is not affected by human subjective feelings, so the judgment result of white water quality is more objective, and provides guidance for the production of reconstituted tobacco leaves and ensuring the quality of tobacco It has a better basic guarantee, so it has a better promotion and application significance in the field of cigarette preparation.

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
