Method to Control Post-Harvest Wood Color
Purdue University researchers have developed a chemical based method to control the post-harvest physiology of wood and lumber. Damage induced biochemical signals that lead to undesirable wood coloration changes can be induced or inhibited during processing that takes place after field harvesting. The technology can prevent the discoloration of white wood lumber, such as yellow poplar and hard maples, or can induce dark coloration in woods, such as black walnut.
Post-harvest process can be readily included in saw mill, lumber sorting, or veneer slicing operationsIn-line process provides shorter processing times with lower inventory levels while eliminating steam chamber equipment and off-line batch processingLow setup costs requiring relatively simple machinerySimple control systems lead to low operating costs
