Abstract

A good aromatherapy experience of an incense stick with filter material depended heavily on the barrier effect of the filter material particles and the comfort temperature of the aroma. The lack of accurate methods to determine the aroma temperature greatly hindered the quality control and product development of aromatherapy. In this study, a novel method was proposed to measure the temperature of the filter material and aroma with an negative temperature coefficient thermistor and a needle thermocouple. The experimental results showed that the measurement accuracy of this method was up to ±0.01°C, and the surface temperature distribution of the filter media and the extracted aroma temperature can be obtained quickly and accurately. It was found that under the two different heating methods, the aroma temperature produced by heating non-combustion was significantly higher than that produced by the non-flaming combustion. Different aroma delivery intervals also had significant effects on the aroma. This paper showed that this novel method could contribute to quality evaluation of filter sticks for aromatherapy products.
