Quillaia Extract In Root Beer [Facts & Safety]

Quillaia Extract In Root Beer

Quillaja is a tree that is native to Chile.

It contains a component called quillaia saponin that is commonly used as a food additive.

It has been used in some root beer brands as a foaming agent and an additive for its supposed medicinal properties.

Traditionally the saponins are used in things like soap production, so is quillaia extract still used in rootbeer?

Quillaia extract in root beer gives it a more decadent foam head.

It has been used as a foaming agent in root beer since the late 1890s, and while different brands use different ingredients, quillaia is still popular today as a root beer additive.

There have been safety concerns around its use since 1994.

Although quillaia is still used in many rootbeer recipes today, there are a few other alternatives available.

When rootbeer was initially invented in 1875, sarsaparilla was used as a foaming agent.

However, that came to an end when the FDA ruled that the sassafras plant was unsafe for mass-produced products.

The quillaia extract was then used as a substitute foaming agent in most rootbeer formulas.

Let us look at the controversy that has followed rootbeer and, more specifically, quillaia extract.

What Is Quillaja Extract?

What Is Quillaja Extract

The extract that is derived from the Quillaja Saponaria tree is called Quillaia (qui-laih-ah).

Traditionally found In Chile and South America, it is extracted from the inner bark.

It was suggested to be used as a medicinal herb to treat various chest ailments and an expectorant, increasing the lungs’ mucus volume making it easy to expel.

In products like rootbeer, quillaia extract is used as a foaming agent.

A foaming agent is added to a beverage to give it more froth and the appearance of a beer foam head – think about a soda float.

In some instances, carbonation is used, but it does not have the same desired effect.

In the food industry, quillaia extract is given the code E999; this makes it easier for manufacturers to print in packaging.

Food safety experts can rapidly identify its properties on their database if needed.  

Is Quillaja Safe?

Is Quillaja Safe

Quillaia extract’s safety came under review again in recent years after a type of thrombosis ( blood clotting issue) was linked to its ingestion.

Both the FDA en the EFSA brought quillaia extract under scrutiny to see if it measures up to the strict laws under current legislation.

In 1978 when quillaia extract was reviewed, the review stated that an acceptable daily intake of the quillaia would be around 5mg of spray dried product per kilo of body weight per day.

However, upon closer review, in 2019, it was decided that 0-1 mg per kilo of body weight is considered safe.

That doesn’t seem like a significant drop in the margin; however, it is an important finding for the extract’s safety.

The absorption in the body of quillaia extract occurs in the gastrointestinal tract to a low extent and could potentially irritate the bowels in large quantities.

Quillaia extract is still considered safe to use in beverages like rootbeer.

How Is Quillaia Extracted?

The extraction method is called – aqueous extraction – This is an environmentally friendly method to use.

In simple terms, the dried leaves are placed in a blender with water.

This is then blended and ground for several minutes until a pulp has been made.

This pulp is then transferred into a centrifuge to spin out all solid material and extract the juice.

It is run through several filters to guarantee purity.

This also ensures that the extract is sterile. It is then stored at around 4 degrees Celcius until it is ready for use in whatever application it is needed.

Quillaia extract contains several interesting components like;

  • Triterpenoid saponins
  • Glucose
  • Arabinose
  • Xylose
  • Galactose and Rhamnose
  • Tannin
  • Calcium Oxalate

The quillaia extract is complex and rich in other micro minerals.

What Gives Root Beer Its Flavor

In the early days of rootbeer production, the bark of the Sassafras tree – Sassafras Albidium – was used as the beverage’s main flavoring.

Another plant or the vine called Smilax Ornate or sarsaparilla root was used in the concoction.

These plants gave the rootbeer its distinctive minty and licorice flavor.

Traditionally root beer is supposed to be alcohol-free as the creator was a teetotaller; it is also caffeine-free and sugary as they used molasses syrup.

Sassafras was used in traditional medicine for a very long time as a blood purifier.

The original rootbeer recipe would have been;

  • Sassafras bark  – This is the distinctive flavor in rootbeer. It produces a uniquely minty flavor. Traditional use – blood purifier.
  • Sarsaparilla root – This root has the flavors of licorice, vanilla, and wintergreen. Traditional use – Kidney tonic and skin purifier.
  • Ginger  – The warm, rich flavor of ginger is unmistakable. Traditional use – cardiovascular support, metabolic or intestinal health, anti-nausea.
  • Licorice – The anise-like flavor and sweetness.  Traditional use – Hormonal imbalance, adrenal support, blood pressure.
  • Dandelion Root – Gives a slightly bitter taste – Traditional use – Liver tonic.

It fermented over a few hours and was a super healthy, probiotic-rich drink.

Those who wanted it slightly more alcoholic than the 2% would let it ferment for longer.

It was commonly drunk by children and was considered healthy and safe.

There is a component in sassafras that has caused so much controversy that the FDA decided to ban it. This component is called safrole.

Recent studies refute the FDA’s claims that safety causes liver cancer in humans after they found evidence of it in rats.

It is more likely that the ban was instituted due to the alcohol content.

There are, however, many other spices we regularly use that also contains safrole or sarsaparilla, and they are;

  • Nutmeg
  • Black pepper
  • Anise seeds
  • Cinnamon

The fact that the study did not ban the use of other safrole-containing products shows that it was most probably done out of fear rather than actual scientific proof.

In a lot of Amish communities, the production of root beer is a booming business.

They usually sell it in their roadside stalls or markets.

Several companies produce rootbeer extracts.

The public can buy these extracts either in stores or online and make their root beer batches at home.
