Quality Control Of Commercial Quillaja (Quillaja Saponaria Molina) Extracts By Reverse Phase HPLC
Saponin-rich extracts of the Chilean indigenous tree Quillaja saponaria Molina are widely used as natural foaming agents in foods and beverages, food emulsifiers, photographic emulsions, vaccine adjuvants, etc. However, with the exception of the vaccine industry, saponin concentration is not adequately quantified. Normally, the quality and price of the extracts are determined using simple foam tests. This may not be adequate, since similar foam levels can be obtained by blending Quillaja extracts with other low-cost saponin sources (eg Yucca shidigera extracts).
