Abstract
A process for the extraction and concentration of saponins from agricultural feedstocks. An agricultural feedstock can undergo a first preparation step intended to increase surface area of the feedstock for increased efficiency in extracting saponin from the feedstock. A saponin extraction step can extract saponin from the prepared feedstock and diffuse the saponin into a solution. A pH adjusted crossflow filtration step can be used to concentrate the saponin into a concentrated saponin solution. One or more pH adjusted centrifugation steps can be used to spin out and concentrate suspended saponin solids. The saponin solids can undergo a drying step to remove any excess water and produce a purified saponin product that can be easily packaged and transported.
