What Is Xanthan Gum Made Out Of? Uses & 6 Benefits

Xanthan gum is a food additive made from sugar that is fermented by a bacteria called Xanthomonas campestris. It is often used as a thickening agent

Xanthan gum is a food additive made from sugar that is fermented by a bacteria called Xanthomonas campestris. Fermentation of sugar creates a broth-like substance, which is then solidified by adding alcohol. This solid substance is dried and turned into a powder.

The sugar used to make xanthan gum may be derived from:

• Sugarcane
• Lactose
• Corn
• Wheat

When added to water, xanthan gum powder quickly disperses and forms a stable, viscous solution. That is why xanthan gum is often added to foods as a:

• Stabilizer
• Thickening agent
• Suspending agent
• Emulsifier

Because xanthan gum is a soluble fiber, it is not digested and instead swells when mixed with water and forms a gel-like substance in the intestine. This gel-like substance stimulates the digestive tract to move and push out the stool. Because of this, xanthan gum may help relieve constipation. 

Soluble fiber can also trap sugars in foods, causing a gradual release of sugars into the bloodstream. This prevents blood sugar spikes, which are often seen in diabetics. In the long term, this helps with blood sugar control.

Xanthan gum can cause some side effects such as intestinal gas and bloating if it is taken more than 15 grams per day.

Examples of products that contain xanthan gum as a food additive include:

• Salad dressings
• Sauces
• Beverages
• Dairy products
• Syrups
• Toppings
• Baked goods
• Mixes
• Bread
• Butter and low-fat spreads
• Frozen foods

Xanthan gums are used as thickening agents in much personal care and beauty products, including:

• Toothpaste
• Creams
• Lotions
• Shampoos

Xanthan gum has some potential health benefits, although more research is needed to prove its efficacy in treating some of the following conditions:

1. Constipation: Xanthan gum swells in the intestine and forms a gel-like substance that stimulates the digestive tract to push out the stool.
2. Trouble swallowing: Xanthan gum helps with swallowing difficulty. The gum thickens the saliva, making it easier for the food to pass down the throat, thereby reducing the risk of choking.
3. Diabetes: According to one study, eating muffins with xanthan gum appeared to lower blood sugar levels in people with diabetes.
4. Sjogren’s syndrome: This is an autoimmune condition that damages glands that produce saliva and tears. Applying xanthan gum to a dry mouth can act as a substitute for saliva.
5. High cholesterol: Xanthan gum in high doses may lower blood cholesterol levels, although sufficient evidence is lacking to support this claim. A previous study found that men who took xanthan gum for about 3 weeks found a 10% reduction in cholesterol.
6. Dry eyes: Xanthan gum may be able to effectively treat dry eyes caused by inflammation. A study has shown that xanthan gum reduces burning sensation, tearing, foreign body sensation, and light sensitivity in people with dry eyes.

According to the FDA, xanthan gum is generally safe when consumed orally:

• Food products containing 0.05%-0.3% of xanthan gum
• Medications containing up to 15 grams of xanthan gum

There is no recommended amount specified for xanthan gum. Even 20 grams of xanthan gum has been proven to be safe. However, inhaling xanthan gum can be dangerous. Workers handling powdered xanthan gum should be cautious because it can cause flu-like symptoms as well as nose and throat irritation.

Who shouldn't take xanthan gum?

• People with severe allergies to wheat, corn, soy, or dairy: Xanthan gum can be derived from wheat, corn, and soy, so people with these allergies should avoid food products containing xanthan gum.
• People taking certain medications or undergoing a planned surgery: Since xanthan gum can lower blood sugar levels, people on diabetes medications should avoid large amounts of xanthan gum.
• People with fecal incontinence: People who have difficulty controlling their stools should not use xanthan gum because it may worsen the problem.
• Pregnant and breastfeeding women: Pregnant and breastfeeding women should avoid xanthan gum although there isn’t sufficient evidence to avoid its use.
• Premature infants: A study has shown that premature infants who are fed xanthan gum can develop severe gastrointestinal problems.
