Novel temperature test method for aroma and filter materials

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