AbstractToexplore the theoretical basis for humiditycontrol limits in conditioned tobacco strips storage,mildew experiments and equilibrium moisture content tests were conducted on tobacco strips.A mold-critical moisture content of 17.0% was used as the standard.Adynamic control theoretical model of natural storage environment parameters for tobacco strips was constructed to study the corelation between the upper limit ofsuitable humidityand temperature in tobacco strips storage environment. The results showed that low-oxygen (oxygen concentration ⩽2% ) conditioned storage could ihibit mold growth in tobacco strips,maintaining stability for 3O days even at a moisture content of 20% . The equilibriummoisturecontent of tobaccostrips waspositivelycorrelated with environmental humidityand negatively corelated with temperature.The second-order polynomial trendline equation for ambient temperature and humidity corresponding to the maximum equilibrium moisture content of 17.0% in tobacco strips is y=0.1669x2+0.0731x+ 68.738, with R2=0.9992 0 y represents the relative humidity of the environment, x represents the point and degree of evolution of the environmental temperature on the x -axis),this equation reveals the correlation between the upper limit of suitable humidity and temperature in tobacco storage environment.When the environmental temperature increased from 10C to 30∘C ,the upper limit of suitable relative humidity for natural storage of tobacco strips rose from 69.0% to 71.7% .The research findings provide a reference for guiding the storage and conservation of tobacco strips by controlled atmosphere.
