Eric Hinsch, WSE Seminar

Extracted wood-staining fungal pigments have shown potential as textile dyes. However, up to this point the primary carrier for these dyes has been dichloromethane, a potentially hazardous solvent. A safer carrier is needed for general consumer use. Natural oils appear to be a good alternative carrier, although there has been a problem with color loss, possible due to oxidation of the oils. In the current study, hemp seed oil, flaxseed oil, MCT oil, and cold-pressed linseed oil are tested for their oxidative stability, both in their natural form and when treated with tocopherol, beta-carotene, and Stoddard solvent. Color loss was tracked by the means of a colorimeter and the CIE L*a*b* color space. Oxidation of the oils, and potentially changes in pigments, were tracked by FTIR. Finally, scanning electron microscopy will be used to determine if there is any change to the crystalline structure of draconin red, the fungal pigment used throughout this study. Preliminary color reading results indicate that hemp seed oil and flaxseed oil treated with beta-carotene may have potential as fungal pigment carriers.
