- E999 Quillaia extract
Quillaia extract is a purified extract of the outer cambium layer of Quillaia Saponaria Molina, or Quillay Bark. The Quillaia tree is native to Peru and Chile, and cultivated in Northern Hindustan. Quillaia bark infusion has good foam capabilities due to the presence of saponin, a non-poisonous, white powder. Saponin is a glucoside which will yield quillaic acid and quillaia-sapotoxin upon decomposure. The latter products are both poisonous irritants, however it is the sapotoxin which foams upon shaking. Quillaic acid is also known as 3,16-dihydroxy-23-oxo-12-oleanen-28-oic acid
Typical products include beer and soda
