Quillaia extract (E 999) is a natural food additive and foaming agent derived from the inner bark of the soapbark tree (Quillaja saponaria). It is widely used to create and stabilize foam in beverages and act as an emulsifier in flavors.

What It Is？

Made from boiling the wood or inner bark of South American soapbark trees.Contains high levels of natural soap-like compounds called saponins, plus tannins and sugars.Available in Type 1 (lower saponin concentration) and Type 2 (ultrafiltered with higher purity).

Quillaja-Extrakt E999

Quillaia extract (E 999) is obtained by aqueous extraction of the milled inner bark or wood of Quillaja saponaria Molina, or other Quillaja species, trees of the family Rosaceae. It contains a number of triterpenoid saponins consisting of glycosides of quillaic acid. Sugars – including glucose, galactose, arabinose, xylose, and rhamnose – are also present, along with tannin, calcium oxalate and other minor components.

Quillaia extract (E 999) was evaluated by the Scientific Committee for Food (SCF) in 1978 who established an acceptable daily intake (ADI) of 0–5 mg spray‐dried extract/kg body weight (bw) per day based on two long‐term studies in rats and mice.

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) established in its latest evaluation a group ADI of 0–1 mg/kg bw per day, expressed as quillaia saponins, for Quillaia extract for Type 1 and Type 2.

The Panel noted that existing EU specifications for E 999 do not describe any range for saponins content in the food additive. The JECFA specifications, however, differentiate two types of Quillaia extracts, Type 1 and Type 2, containing a different percentage of saponins and other parameters. The Panel considered that similar differentiation of the extracts of Quillaia should be presented in the EU specifications, including the percentage range for saponins, polyphenols (including tannins), protein, polysaccharides including fibre, reducing sugars, a maximum limit for calcium oxalate as well as microbiological specifications.

The Panel assumed that the test materials used in toxicological studies described as Quillaia extract approximated to Quillaia extract Type 1 as described in JECFA.
