System and method for detecting content of water-soluble total sugar in tobacco

The invention provides a system and method for detecting the content of water-soluble total sugar in tobacco, and the system for detecting the content of water-soluble total sugar in tobacco comprises an acidolysis reaction module, a neutralization and dilution module and a color development-detection module which are connected in sequence, the acidolysis reaction module comprises a first sample introduction unit, an acidolysis reaction unit, a separation unit and a pressurization unit which are connected in sequence. The pressurization unit is creatively arranged in the acidolysis reaction module, so that the saturated vapor pressure of the solution is increased, bubbles and even boiling of the solution at a high temperature are avoided, and sufficient reaction at the high temperature is ensured. The method for detecting the water-soluble total sugar in the tobacco, provided by the invention, is high in accuracy, good in reproducibility and stable in result, is not influenced by external climate, well solves
