Effects of Altitude and Relative Humidity on Sensory Quality of Cigarette

In order to investigate the influence of altitude and relative humidity on the indexes of cigarette sensory quality,11 sensory indexes of a certain cigarette brand were sensory evaluated in 16 cities and analyzed by MBA(Multilevel B-spline Approximation).The results showed that the sensory indexes changed with altitude and relative humidity.At an altitude range of 0 to 1000 m and relative humidity of 30% to 50% or 60% to 80%,smoke showed better aromatic characteristics(flavor note,aromatic quantity and quality);At an altitude between 200 and 700 m and relative humidity of 60%-80%,it showed higher smoke characteristic(thickness);while at an altitude between 0 and 1000 m and relative humidity of 60%-80%,it offered better mouth feeling(irritation,smoke moistness,cleanness and aftertaste).The evaluation results showed that the sensory quality of cigarette was better in the whole when altitude was below 1000 m;if relative humidity was in the range of 30%-50% or 60%-80%,the best.
