Abstract

1) We investigated color changes on the outer surfaces of Phyllostachys bambusoides bam-boo by heat treatment under three different temperatures (180°C, 200°C, and 220°C) for three different durations (60 min, 90 min, and 120 min). A method of predicting the bam-boo surface color change after heat treatment was developed to provide valuable information and increase the added value of domestic bamboo products. The three average color parameters L*, a*, and b* decreased, and the overall color changes increased as the severity factor increased. The values of L* × a* × b* were highly related to the severity factor, and the optimal duration time for the desired bamboo surface color with a certain heat-treatment temperature could be estimated.

热空气热处理对毛竹表面颜色的影响

1）我们研究了在三种不同温度（180°C、200°C和220°C）下经过三种不同持续时间（60分钟、90分钟和120分钟）的热处理后竹外表面的颜色变化。为了提供有价值的信息，提高国产竹制品的附加值，开发了一种预测热处理后竹表面颜色变化的方法。随着严重程度因子的增加，三个平均颜色参数L*、a*和b*降低，总体颜色变化增加。L*×a*×b*的值与严重程度因子高度相关，可以估计出在一定热处理温度下所需竹子表面颜色的最佳持续时间。

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
