Title: David Paton: Innovator in Saponin and Lignan Extraction
Introduction
David Paton is a notable inventor based in Saskatoon, Canada. He has made significant contributions to the field of extraction processes, particularly focusing on saponins and lignans. With a total of 4 patents to his name, Paton has developed innovative methods that enhance the commercial viability of natural compounds.
Latest Patents
One of Paton's latest patents is a process for the recovery and purification of saponins and sapogenins from quinoa (Chenopodium quinoa). This process involves contacting a saponin-containing part of the quinoa plant with an aqueous alcohol solution, which leads to the formation of a saponin-containing solution. The method includes removing the alcohol to yield a saponin-containing aqueous solution and evaporating water to produce a saponin product. Additionally, the conversion to sapogenins is achieved by hydrolyzing the saponins with a strong acid, resulting in a precipitate that can be recovered and decolorized.
Another significant patent involves a complex containing lignan, phenolic, and aliphatic substances derived from flax. This complex is obtained through an aqueous aliphatic alcoholic extract from flax, which is subjected to ultrafiltration. This process allows for the separation of higher molecular weight species, resulting in a substantially pure chemically bound complex.
