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.

Abstract: Process for enhancing production rates/production of yeast cell wall products and yeast extracts by adding saponin or a saponin containing ingredient to yeast cultures during fermentation or to yeast cream prior to autolysis. In the context of a sugar beet processing facility, saponin, which is contained within the sugar refining process streams during sucrose production, is readily available and can be introduced to the yeast cultures or yeast cream as either a saponin extract or as dried and shredded sugar beet leaves, without requiring any additional sourcing or acquisition costs. Activity between the saponin and yeast/yeast cream results in the formation of saponin fermentation products.
