All About Emulsifiers: What You Need to Know

What exactly are they, and how do they impact our health? Let’s dive into the world of emulsifiers.

What Are Emulsifiers?

At their core, emulsifiers are additives that blend ingredients that naturally don’t mix, such as oil and water. They’re everywhere in the food supply. A recent study found that 51.7% of food products in the UK contain emulsifiers. Considering their omnipresence, understanding their implications is more important than ever.

Where Can You Find Emulsifiers?

Emulsifiers are used in everything from salad dressings and ice cream to bread and plant-based dairy alternatives. Popular examples include lecithin, mono- and diglycerides, CMC, polysorbates, carrageenan, and more. Interestingly, there are over 60 types of emulsifiers in the UK food supply, and they’re not always explicitly listed as “emulsifiers” on labels. Instead, they might be referred to by names like “gums” or their specific chemical designations.

Here’s a snapshot of common emulsifiers and their functions:

Carboxymethyl cellulose : Found in milk, ice cream, and some baked goods; but also, in pharmaceutical products like ibuprofen liquid medicine for babies.

Carrageenan (from red seaweeds): Thickens plant-based milks and prevents crystal formation in ice cream.

Lecithin (from soy or egg yolks): Stabilises chocolate and confectionery.

Xanthan gum (produced via microbial fermentation): Used for elasticity in gluten-free baking.

Are There Any Benefits?

It depends how you view benefits. They do of course extend shelf life, and through taste and texture improvements they make lower fat or lower sugar food options more palatable. It’s easy to see how they’ve made their way into the food industry in such a big way. However, for consumers, the benefits might come at a cost, particularly regarding health.

Health Impacts of Emulsifiers:

Emerging studies suggest that emulsifiers may disrupt gut health, affecting the balance of gut bacteria and causing inflammation. This inflammation has been linked to conditions like metabolic syndrome and inflammatory bowel diseases (IBD) such as Crohn’s and ulcerative colitis. Some emulsifiers are also restricted on low FODMAP diets due to their high fermentable carbohydrate content.

Spotlight on Specific Emulsifiers:

Carboxymethyl Cellulose (CMC): Found in baked goods and ice cream, CMC has been shown to inflame the gut and alter microbiome composition in animal and human studies.

Polysorbate-80 (P80): Used in medications and food, prolonged consumption is associated with gut inflammation and metabolic issues.

DATEM: Common in bread production, this emulsifier has been linked to heart fibrosis and low-grade inflammation, though more research is needed.

Carrageenan: Some studies suggest that it may cause inflammation in the digestive system, potentially leading to issues like bloating, irritable bowel syndrome (IBS), and other gastrointestinal discomforts. There’s also concern about its potential to disrupt gut health by altering the microbiome

Gum Arabic: The star of the emulsifier world! Derived from the Acacia Senegal tree, it offers health benefits like promoting beneficial gut bacteria growth and reducing blood pressure.

What’s the Verdict?

While emulsifiers undoubtedly bring convenience and versatility to modern food production, their potential health impacts cannot be ignored. As research continues to shed light on their effects, it’s worth being mindful of the emulsifiers in your diet and opting for minimally processed foods whenever possible.
