Color changes of Pinus densiflora, oil heated at the temperature of 180ºC and 200ºC, and convection air heated at the temperature of 200ºC were investigated. Belgian flaxseed oil was used for oil heating treatment. Color indexes of CIE L*a*b* were measured by using HunterLab MiniScan XE Plus. It was revealed that heating temperature was more influencing factor than heating media, such as oil and convention air. Oil heating at the temperature of 200ºC resulted in more uniform and effective color change of Pinus densiflora specimens than the convection air heating treatment at the temperature of 200ºC and the oil heating treatment at the temperature of 180ºC.
