We have developed and patented innovative technologies that transform biomass-based (e.g. wood or lignin) starting materials into sustainable fine chemicals, such as capsaicin and nonivamide. The method is environmentally friendly and provide the end-products of guaranteed high quality. Our capsaicin has the same properties as naturally extracted capsaicin with better predictable properties. It is free from impurities and heavy metals. Furthermore, our capsaicin maintains a uniform quality and purity which makes dosing easy.
